Do these include authentication or a database?

They include the screens, not the backend. Auth forms, billing pages and settings are wired to props and callbacks so you can drop in your own provider — a template that picked one for you would be wrong for most people.

How much of this is Next.js specific?

The routing and the layout files. The components are React with Tailwind, and the CLI can convert the markup to Vue, Svelte, Astro or plain HTML if the rest of your stack is not Next.

Are these saas website templates free to use?

4 of the 21 are free to copy and use commercially; 17 need a Pro licence, and each one says so on its own page before you spend any time on it.

How do I add one to my project?

Install it with the CLI: `npx hoverlab add saas-starter` writes the component and its dependencies into your project. Every artifact here also has a copy button for the raw source, and an "Open in sandbox" link if you would rather try it first.

What people say

From teams that ship on a deadline.

“We replaced a week of design polish with an afternoon. The parts that used to get cut for time are just there now.”

Priya RamanStaff Engineer, Northwind

“Dropped it in on a Friday and shipped Monday. No dependency argument with my team for once.”

Marco SilvaFounder, Ferrytale

“The thing I did not expect: it made our junior engineers faster, because the patterns are readable. They learn from what they paste.”

Alex ChenEngineering Manager, Contoso

“Our marketing site went from three weeks to four days. Same designer, same headcount.”

Dana WhitfieldHead of Design, Globex

“I stopped keeping a personal snippets file. That file had been following me between jobs for six years.”

Frequently asked questions

Everything people ask before getting started.

Can I use this in a commercial project?

Yes. Everything here is yours to ship in client work and paid products, with no attribution required.

Do I need a specific framework?

No. The markup is plain HTML and the styling is utility classes, so it drops into any stack that can render an element.

How do updates work?

Copied code is yours — nothing reaches back into your project. Pull a newer version whenever you want it.

Is there a free tier?

There is. A large part of the catalog is free forever; the paid plan unlocks the rest and removes usage limits.

Before you decide

The questions people ask right before they buy.

Can I change plan later?

Any time, in both directions. Upgrades take effect immediately and are prorated; downgrades apply at the end of the current period so you keep what you paid for.

What happens when I hit a limit?

Nothing breaks. We email you at 80% and again at 100%, and usage above the limit is billed at the listed overage rate rather than being cut off mid-request.

Do you offer refunds?

Within 30 days, in full, no questions asked. After that we will prorate the unused portion of an annual plan if you ask.

Is there a discount for annual billing?

Two months free — that is the 20% you see on the toggle. Annual plans are invoiced and can be paid by bank transfer.

Do you have startup or nonprofit pricing?

Yes to both. Email us with a sentence about what you are building and we will sort it out — we have never said no to a nonprofit.

Still not sure which plan?

Start on Free. You will know within a week whether you need more, and upgrading takes one click with no migration.

Q3 churn review

Started 14 minutes ago · 4 tools used · reading 3 sources

Why did churn spike in Q3?

Thought for 5.1 seconds5 steps

Dropping the largest single cancellation moves the under-20 figure from 6.1% to 5.4%. The pattern holds, so it is a cohort effect and not an outlier.

Churn concentrated in accounts under 20 seats, which lost 6.1% of ARR against 1.4% in the rest of the book 1 — see source 1. The common thread is activation rather than price: teams that never connected a second data source churned at roughly four times the rate of those that did 2 — see source 2. Only 11% of the cancellations cited cost in their exit survey, and most of those had already downgraded once 3 — see source 3.

Most of what reaches our inbox is answered on this page in about forty seconds. The four below are what people ask for most.

Popular

The six that come up most

Ordered by how often they arrive, not by how interesting they are.

I have lost my two-factor device.: Use one of the eight recovery codes issued when you turned 2FA on. If those are gone too, a workspace admin can reset your second factor from Settings → Team; we cannot do it for you, because a support agent who can disable 2FA is a way around 2FA.
Who receives our invoices?: The billing email on the account, which is separate from the owner’s login and can be a shared inbox. Change it under Billing → Details; the next invoice uses it, and past invoices are re-sendable to the new address from the same screen.
How do I get all of our data out?: Account → Export produces a ZIP of JSON and CSV, everything you have put in, with no plan gate and no notice period. Large workspaces are emailed a link when the file is ready, usually within the hour.
We have hit the seat limit mid-sprint.: Adding a seat is instant and prorated to the day — nobody is blocked while an invoice clears. If you would rather not add one, deactivating a dormant member frees their seat immediately and keeps everything they wrote.
Someone has left the company. What happens to their work?: Deactivate rather than delete. Their documents, comments and history stay where they are and reassign to whoever you name; deleting the account removes the person and keeps the work, but the audit trail then reads "deleted user", which is harder to answer questions about a year later.
Why is a page loading slowly for one person only?: Almost always a stale service worker. A hard reload fixes it. If it survives that, check the status page above — a regional degradation shows up as one office being slow while the rest of the company is fine.

Still stuck

One person reads every one of these. Include what you expected, what happened, and the workspace name — that is the difference between an answer and a first reply asking for details.

Waiting on a person

Sorted by age, not arrival. A queue sorted newest-first buries the item that has been stuck longest, which is always the one that turns into the complaint.

What runs without asking

Approval prompts are trusted in proportion to how predictable they are. Someone who cannot say in advance which actions will stop and ask learns to approve everything.

Cutting p95 checkout from 2.4s to 610ms by removing the cache

The cache was hiding a query plan that went quadratic above 400 line items. Invalidation cost more than the reads saved, so the fix was a delete and one index. Six weeks, no downtime, no rewrite.

An exchange that publishes the number you are actually paying

Spot trading on 214 assets, a real order book, and a fee schedule on the same page as the marketing. Withdraw to your own wallet whenever you like — there is no lock-up and never was.

30-day spot volume: $4.1bn
Taker fee, entry tier: 0.10%
Assets listed: 214
Reserves, attested monthly: 1:1

Custody

Where the money actually is

The four facts that decide whether an exchange is safe to use, each one checkable rather than asserted. If a venue will not answer these, that is the answer.

98% in cold storage: Offline
Client assets segregated: Ring-fenced
Proof of reserves: Monthly
Insurance on the hot wallet: $250m

Operations

Measured, published, and externally checked

Numbers from the last twelve months. The status page is third-party hosted, so it stays up when we do not.

Matching engine uptime: 99.99%
Median withdrawal: 4 min
Order latency, p99: 11 ms
Regulated in: 9 markets

Three things, done properly

We are not trying to be a bank, a card, a social network and a launchpad. Trading, custody and reporting — and the reporting is the one everybody else treats as an afterthought.

Trade

A real order book, not a swap widget

Limit, market, stop and trailing orders on every pair, with the full depth visible and no hidden spread priced into the quote you are shown.

Post-only and reduce-only flags on every order type
The spread is shown; we do not widen it and call it "zero fee"
REST and WebSocket APIs on the same rate limits we use ourselves

Hold

Withdraw to your own wallet, always, without asking

Self-custody is a right and not a feature. There is no minimum holding period, no withdrawal lock on a promotional balance, and no support ticket between you and your keys.

Whitelist addresses with a 24-hour cooling period you control
Hardware-key 2FA, and no SMS fallback that defeats it
A full CSV and API export of every movement, going back to day one

Report

The tax export your accountant will accept

Cost basis computed per jurisdiction, including the disposal rules that differ between the UK, Ireland and Germany, with the working shown rather than a single number.

FIFO, LIFO and average-cost, switchable per tax year
Direct export to three filing tools, or plain CSV
Free on every tier — a tax report behind a paywall is a hostage

The fee schedule, in full

Volume bands, not subscription plans — there is no monthly charge and nothing to cancel. Your band is recalculated every day on a rolling 30-day window.

The fee schedule, in full — features by plan

Risk warning

Read this part before the marketing

Crypto assets are unregulated in several of the markets we serve and are high risk everywhere. This section is required by law in most of them and we would print it anyway.

The value of crypto assets can go down as well as upYou may get back less than you put in, and you may get back nothing at all. Past performance tells you nothing about future returns.
Crypto assets are not covered by a deposit guarantee schemeUnlike a bank account, there is no FSCS or equivalent compensation if we fail. This is why segregation and proof of reserves are on this page.
You are responsible for your own tax positionWe produce the report; we do not file it and we are not your accountant. Disposals are usually taxable even when you never touch fiat.
Do not trade with money you needWe will not lend you money to trade, we do not offer leverage to retail clients, and we would rather lose the account than the customer.

The questions worth asking any exchange

Including the ones we would rather you did not ask. If a competitor cannot answer these in writing, that tells you something.

Still deciding?

Our compliance team answers questions about custody and segregation directly, in writing, before you deposit anything.

Ask compliance a question

How do I know my money is not being lent out behind my back?

Because client assets sit in a separate, bankruptcy-remote entity and the monthly attestation is a Merkle tree you can check your own balance against — the leaf hash is in your account settings. We do not run a yield product, which is the mechanism by which this usually goes wrong.

What happens to my assets if you go out of business?

Client assets are segregated, so they are not part of the estate. The administrator returns them; they do not distribute them to our creditors. That is a legal structure rather than a promise, and it is the one question worth checking on any exchange.

Is "zero fee" trading elsewhere actually cheaper?

Usually not. Zero-fee venues make the money back on the spread, which is invisible at the moment you trade. Our spread is the order book’s and our fee is on this page, so the total cost is something you can calculate before you press the button.

Why do you need my identity documents?

Anti-money-laundering rules in all nine markets we are authorised in. We ask for the minimum the rule requires, delete the raw images after verification, and never sell or share the data. An exchange that skips this step is one regulatory action from freezing your withdrawals.

Can I use this through an API for a trading bot?

Yes, on every tier, with the same rate limits our own front end uses. Keys are scoped — a read-only key cannot place an order and a trading key cannot withdraw, which is the separation that saves people when a key leaks.

Sponsorship pays for the community tickets, the captions and the recordings. It does not buy a talk — every session on the programme went through the same review, and three sponsors submitted and were turned down this year.

Three tickets

One price, paid once, and the same two days in all three. The differences are lunch, the workshops and the dinner — there is no version of this event where you see fewer talks.

Before you book

The logistics that decide whether a ticket is usable, answered properly rather than in a line each.

Something not covered?

Two of us read this inbox and we answer before you pay, not after. Access requirements especially — ask first.

Email the organisers

What is the community ticket and who is it for?

It is the same two days at €180, for students, people between jobs, and anyone whose employer is not paying. Nobody is asked to prove any of that — you tick a box. We hold 80 of them and they are funded by the sponsor tiers, not by the other ticket types.

Are the talks recorded, and are they free afterwards?

All of them, published to the public within two weeks, no login and no paywall. Workshops are not recorded because the value is in the room and a camera changes how people ask questions.

Can I get a refund if I cannot come?

Full refund until 1 April, no reason needed. After that the ticket is transferable to anyone else right up to the morning of the event — change the name in your order and that is the whole process.

What does "no keynote clashes" mean?

Three tracks run in parallel, but the two keynotes and the closing panel run alone with nothing scheduled against them. Nobody should have to choose between the talk everybody will discuss and one they specifically came for.

How accessible is the venue?

Step-free throughout, including the stage. Live captions on every talk in the Great Hall and Room A, a quiet room open both days, and hearing loops in all three rooms. Email us before you book if you need something not listed here and we will answer before you pay.

Is there a code of conduct and is it enforced?

Yes, and yes — it is linked in the footer, it names the three people on the response team, and they are at the event both days with a phone number printed on every badge. It has been used twice in four years and both reports resulted in action.

420 tickets, and 190 have gone

The early-bird price holds until the end of February. After that it steps up once, and it does not step back down.

How it works

Four things worth knowing before you book

None of them are unusual in a good restaurant and most restaurant websites leave all four out, which is why people arrive expecting something else.

One menu, changed when the produce changesNot seasonally and not on a schedule — when the box that arrives on Tuesday is different, the menu is different on Wednesday. It is why there is no printed menu and why the website is the menu.
Everything from within about ninety milesExcept the salt, the pepper and the olive oil, and we are not going to pretend otherwise. The lamb is from one farm on the Mendips and the fish comes up from Brixham on the same van every morning.
Six people, and that is the whole businessTwo in the kitchen, two on the floor, and the two of us who own it working both. Service charge goes to them and is split evenly including the kitchen, which is not the industry norm.
One sitting per tableYour table is yours for the evening. We would rather do 38 covers properly than turn 70 and ask you to leave before pudding.

What people say

Four of the 312. The four-star one is here on purpose — the room really is loud when it is full, and we would rather you knew that before you booked an anniversary.

“The hogget for two is the best thing I have eaten in this city. Carved at the table, gone in twenty minutes, and they were not precious about us ordering three puddings between two.”

Ffion R.Booked for an anniversary

“Small room, so book. We turned up on a Saturday without one and were sent away kindly, which is fair enough. Came back Wednesday and it was worth the wait.”

Daniel O.Local, now a regular

“Told them about a nut allergy when booking and they had already crossed two things off by the time we sat down. Nobody made it a performance. That is rarer than it should be.”

Sameera K.Dinner for four

“Excellent food, and honestly quite loud when it is full. If you want a quiet conversation take the early sitting at six rather than eight.”

Profiling, end to end

Where the time actually goes

48,219 views · Episode 3 of 7 · Published 4 March

We take a page that feels slow and find out what is actually slow about it — with a profiler open the whole time, and no guessing. The fix at the end is two lines; finding it is the other eleven minutes.

The four things people ask before subscribing

Downloads, ads, subtitles and sharing — in that order, because that is the order they come up. None of them is an upsell.

Download anything, keep it 30 days
Every episode, at full quality, on up to four devices. Nothing expires after 48 hours the way it does elsewhere, and a download you started stays valid if your subscription lapses mid-series.
No ads, ever, on any plan
There is one plan and it has never had an ad tier, a "with ads" discount, or a mid-roll. This is a product decision rather than a current promotion.
Subtitles and transcripts on everything
Human-written, not auto-generated, in six languages. Every episode also has a searchable transcript, which is how most people actually find the bit they wanted to re-watch.
Five profiles, and no household check
Watch on three screens at once from anywhere. We do not check IP addresses, ask for a verification code, or have an opinion about who is in your household.

One plan, and it is the best one

No ad tier, no 4K surcharge, no annual lock-in. The thing you can buy is the whole thing.

Longform

£9a month

Subscribe for £9 a month

About 40 hours are free to watch with no account at all, including the whole first series. Try that before you pay for anything.

What is included

240 hours, everything in the catalogue
4K HDR wherever the source allows
Downloads that keep for 30 days, on four devices
Three simultaneous streams, five profiles
Human-written subtitles and transcripts, six languages
No ads, and there has never been an ad tier
Cancel in two clicks, effective at the end of the period

Before you subscribe

Cancellation, downloads, sharing and price rises — the four places streaming services usually disappoint people.

Something else?

Support is email and it is answered by people who work here, usually within a day and always within three.

Email support

Can I cancel whenever I want?

Yes, from the account page in two clicks, and it takes effect at the end of the period you have already paid for rather than immediately. No retention flow, no phone call, and no offer of two months free on the way out.

What happens to my downloads if I cancel?

Anything already downloaded stays playable for 30 days from when you downloaded it, including after the subscription ends. Most services revoke on cancellation; we think that is mean, given you paid for the month.

Is there a free trial?

No trial, and the first month is the same price as every other month — but roughly 40 hours of the catalogue is free to watch without an account at all, including the whole first series of Profiling. Watch that and decide.

How many people can watch at once?

Three streams, five profiles, and we do not check where they are. No household verification, no travel restrictions, and no "you seem to be away from home" email.

What quality does it stream at?

4K HDR where the source allows, adaptive down to about 1.5Mbps. There is no quality tier and no surcharge for 4K — the plan you can buy is the best one there is.

Will the price go up?

It has once in five years, from £7 to £9, announced two months ahead. If it changes again, existing subscribers keep their price for twelve months and are told before it happens rather than in the receipt.

Sign in Get API key

Authentication

Every request to the Acme API is authenticated with a bearer token. This page covers creating a key, storing it safely, and rotating it without downtime.

Acme issues two kinds of keys. Secret keys (prefixed sk_live_) can read and write everything in your project and must only ever live on a server. Publishable keys (prefixed pk_live_) are safe to ship in a browser bundle and can only create client sessions.

Keys are scoped to a project, not to your account. Deleting a project revokes its keys immediately; removing a teammate does not, so treat offboarding as a reason to rotate.

Creating an API key

Create a key from the dashboard under Settings → API keys, then pass it as a bearer token on every request:

curl https://api.acme.dev/v1/projects \
  -H "Authorization: Bearer $ACME_API_KEY"

Note: the full secret is shown once, at creation. Acme stores only a hash, so a lost key cannot be recovered — it can only be rotated.

Rotating keys

Rotation is overlap, not replacement: create the new key, deploy it everywhere, and only then revoke the old one. Both keys stay valid during the window, so a slow rollout never turns into an outage.

Principal engineer — platform, performance and the unglamorous parts

Print or save as PDF

Ten years building systems that other engineers depend on, mostly by removing things. I am at my best on a team that has outgrown its first architecture and has to keep shipping while it changes. Looking for a principal or staff role where the hard problem is technical rather than political.

Experience

Principal Engineer, Platform · Northwind
Mar 2023 — Present · Remote
Series B logistics platform, 40 engineers, one Rails monolith and four Go services.
- Cut p95 checkout latency from 2.4s to 610ms by deleting a caching layer rather than adding one — the invalidation cost more than the reads saved.
- Led the migration off a managed search product onto Postgres full-text, against a hard contract-expiry date. Saved $310k a year with no change to result quality anyone could measure.
- Wrote the on-call handbook and cut pages per engineer per week from 11 to 2, mostly by deleting alerts nobody had ever acted on.
Senior Software Engineer · Contoso Health
Jun 2019 — Feb 2023 · Dublin
Patient records for 60 clinics. Regulated, audited, and slow to change by design.
- Rebuilt the appointment booking flow to meet WCAG 2.1 AA before the deadline the procurement contract set. It passed audit first time, which nothing else that year did.
- Introduced contract tests between the scheduling service and three consumers, ending a class of release that broke a downstream team every quarter.
Software Engineer · Umbra Labs
Sep 2016 — May 2019 · Dublin
- Second engineer. Built the billing integration that the company ran on unchanged for six years.

Our numbers

What we actually achieve, published

From our own completed sales over the last twelve months, not from a national index. Any agent can quote the market; these are the four figures that separate one agent from another, and most will not print them.

Average time to sell: 41 days
Achieved against asking: 98.4%
Sales that fell through: 11%
Fee, sole agency: 1.2% + VAT

Thinking of selling?

A valuation takes about forty minutes and comes with the three comparable sales it is based on, so you can check the reasoning rather than trust the number. There is no obligation and we will not ring you afterwards unless you ask.

Book a valuation Get an instant estimate

1.2% + VAT, sole agency, no withdrawal fee
Eight-week term, then two weeks’ notice
Every viewing conducted by one of the four of us

Questions sellers should ask every agent

Including the two that are awkward. If an agency cannot answer these in writing before you sign, that is the answer.

Ask us something else

One of the four partners answers this inbox, usually the same day. No call-back form and no lead-qualification script.

Email the partners

What does the 1.2% actually cover?

Photography, floor plan, EPC, the listing on the two portals that matter, every viewing accompanied by one of us, and the negotiation. There is no separate marketing package and no charge if we do not sell it. The only thing you pay for separately is a conveyancer, and they are not us.

How long am I tied in for?

Eight weeks of sole agency, then it rolls month to month and you can leave with two weeks’ notice. Twelve- and sixteen-week tie-ins are common in this city and they exist to protect the agent, not you.

Will you tell me my house is worth more than it is?

No, and this is the main thing that loses us instructions. Over-valuing wins the listing and then costs the seller three months and a reduction. Our valuation comes with the three comparable sales it is based on, and you can check every one of them on the Land Registry yourself.

Who conducts the viewings?

One of the four of us, always, including evenings and Saturdays. We do not send a viewings assistant who has never been in the house and cannot answer a question about the boiler.

Do you charge for professional photography?

No. It is in the fee, it is done by a photographer rather than a phone, and it includes a floor plan with measurements. A listing without a floor plan gets materially fewer enquiries and we are not going to sell you one as an upgrade.

What happens if I take it off the market?

Nothing. No withdrawal fee and no invoice for work done. Circumstances change, and an agency that charges you for changing your mind has made your decision about them for you.

Recruiter spam

Your profile is not sold

Four rules, applied to every listing

They are why postings get rejected and why the board is smaller than the big ones. That is the trade, and it is deliberate.

A salary range, or it does not go up
Not "competitive", not "DOE", and not a range so wide it is meaningless. We reject about one posting in six on this rule alone, and we tell the employer why.
No agencies, ever
Every listing is posted by the company doing the hiring. You will never apply through a middleman who cannot answer a question about the team.
Remote means remote, with the countries named
"Remote" that turns out to mean one time zone and a visa you do not have wastes a fortnight. Employers list the countries they can actually employ in.
The process is published before you apply
Number of stages, whether there is a take-home, how long it is, and whether it is paid. On the listing, not in an email after the first call.

Hiring? £199 for thirty days

One price, one listing, shown the same way as everybody else’s. No subscription and nothing to cancel — and we will tell you before it goes live if the range needs work.

Post a job Buy ten for £1,490

Reviewed by a person within one working day
Expires after 30 days unless you confirm it is still open
Refunded in full if we reject it

How this board works

For both sides, since the rules are the product and they only work if everyone knows them.

Something wrong with a listing?

Every posting has a report link and it reaches a person, not a queue. Salary bands that look wrong are the report we act on fastest.

Report a listing

Is it really free for candidates?

Yes, and there is no account required to browse or to apply — applications go straight to the employer’s own system. We make money from employers posting, which is the only model where our incentives and yours point the same way.

Why do some listings have a wide salary band?

Usually because the role spans two levels. We allow a band up to about 35% wide and reject anything broader, because past that the number stops being information. If a band looks wrong to you, the report link on every listing reaches a person.

Will my details be sold to recruiters?

No. There is no candidate database to sell — we do not have one. Applications are passed to the employer and nothing is retained beyond a count. This is the main reason the board exists.

How do I know a listing is still open?

Every posting expires after 30 days unless the employer confirms it is live, and the date it was last confirmed is on each listing. Roughly a fifth of postings lapse this way each month, which is the point.

Can I get new roles by email?

One email a week, filtered to the crafts and countries you pick, and unsubscribing is one click from any of them. No "we miss you" emails, and the list is never rented.

I am an employer. What does it cost?

£199 for a 30-day posting, or £1,490 for ten to use over a year. No subscription, no annual contract, and no upsell to a "featured" slot — every listing is shown the same way.

The whole API is one object and two files

A config, and migrations that are plain SQL. If you already know how to write an ALTER TABLE you know how to use this.

Migrations are SQL files — nothing to learn, nothing to unlearn
The guard is the only unusual concept, and it is four lines
Irreversible migrations are declared, not inferred

1import { Ratchet } from 'ratchet'2 3// A migration is a file, not a class. The up is required; the down is4// optional and, if you leave it out, the migration is declared5// irreversible and the tool will say so rather than guess.6export const ratchet = new Ratchet({7  dir: './migrations',8  url: process.env.DATABASE_URL,9 10  // The whole point of the library. Before applying anything that drops11  // or narrows a column, parse the queries in these paths and refuse if12  // one of them still reads it.13  guard: {14    scan: ['api/**/*.go', 'reports/**/*.sql'],15    onConflict: 'block',16  },17})18 19await ratchet.up()

Why this rather than the one you already have

Five differences. The first one is the reason the project exists; the others are consequences of keeping it small.

It reads your code before it drops a column

The guard parses the queries in the paths you name and blocks a destructive migration while anything still reads the column. Most outages caused by a migration are this exact shape.

Plain SQL, no DSL

Your database’s own documentation is the reference. Nothing to learn and nothing that stops working when Postgres adds a feature.

Irreversible is a thing you declare

A migration with no down is fine — lying about it is not. Say so in a comment and the plan output says so too.

No lock held while it thinks

Planning happens before the transaction opens, so a slow guard scan never holds a lock on a production table.

One binary, no runtime

6MB, static, no Node or Python needed in the image that runs it. The library and the CLI are the same code.

Funding, since you are about to depend on it

Two maintainers are paid part-time; the rest is volunteered

Northwind funds one day a week and Contoso funds two, both on rolling twelve-month agreements, and neither gets any say over the roadmap — that is written into both. If both stopped tomorrow the project would keep going more slowly rather than stopping, because no single contributor holds more than 19% of commits. This paragraph is here because it is the question a team should ask before taking a dependency, and most projects do not answer it.
