Free for your first 10,000 visitors a month, with all three statistics engines included. Paid plans start at $149 a month, add the AI copilot, and scale with your traffic. Unlimited seats and projects on every plan. Every price is on this page. You subscribe and cancel yourself, with no sales call and no contract anywhere below Enterprise.
The free plan is a real plan, not a trial. AI is the one thing Free leaves out, and custom roles are the one thing only Enterprise adds. Free and Pro are self-serve: subscribe, change or cancel yourself, and download your own invoices. Only Enterprise needs a conversation.
Everything you need to run your first experiments.
10,000 visitors / month
For teams shipping experiments to real traffic every week.
50,000 to 1,000,000 visitors / month
For agencies and high-traffic teams with custom needs.
1,000,000+ visitors / month
Drag the slider to the traffic you actually get. The rung you land on is the price you pay, and paying yearly is 2 months free. The whole ladder is printed underneath, so you can see what the next step up costs before you commit to anything.
| Monthly visitors | Per month | Per 1,000 visitors | Per year | AI actions | Data history |
|---|---|---|---|---|---|
| 50k | $149 | $2.98 | $1,490 | 100 | 1 year |
| 100k | $249 | $2.49 | $2,490 | 150 | 1 year |
| 200k | $459 | $2.30 | $4,590 | 250 | 2 years |
| 300k | $659 | $2.20 | $6,590 | 350 | 2 years |
| 500k | $1,049 | $2.10 | $10,490 | 500 | 2 years |
| 750k | $1,529 | $2.04 | $15,290 | 700 | 2 years |
| 1M | $1,999 | $2.00 | $19,990 | 900 | 2 years |
Yearly prices are ten months for twelve, so every one of them is 2 months free. Above the top rung, Enterprise takes over and the volume is agreed with you.
You can check the rules rather than take the numbers on trust. Both hold at every volume on the ladder above, and the second one is why there is no quote to request.
Every step up the ladder costs less per visitor than the step below it, from $2.98 per thousand visitors at 50k down to $2.00 at 1M. Growing never puts you on a worse rate than you had before.
We check each rung against what a full-featured testing tool lists at the same traffic, and every rung of ours sits below it. That is a rule we price by, not a launch offer with an end date.
Early customers keep their price. If our prices go up, yours never does.
Traffic is the only thing that changes the price. Seats, projects, experiments and feature flags are unlimited on every plan, including Free. AI is the paid line, custom roles are the Enterprise line, and everything else is identical on all three.

What counts as a visitor, why Free has no AI, what going over costs you (nothing), how refunds work, and what yearly billing does.
Any unique visitor put into an experiment or checked against a feature flag in a calendar month, added up across every project in your organisation. Anonymous visitors count. The same visitor coming back later in the month does not count twice. It is the traffic number you already know from your analytics.
Every AI request costs us real money, so the AI copilot and the AI assistant are the one thing the free plan leaves out. Paid plans include 100 to 900 AI actions a month, scaling with your traffic and shared across your whole organisation rather than counted per seat. A straightforward request uses one action, a large one uses a few and the screen says so, and you can top your actions up from the billing screen whenever you want more.
Nothing stops and nothing is charged automatically. Every plan carries 10% over its visitor allowance as breathing room, and we email you the first time you cross it. If you finish a second month in a row above the buffer, we ask you to move up a plan before you start any new experiments. Experiments already running keep running, tracking never stops, and every result you have stays available.
Yes. Ask within 7 days of your first payment, monthly or annual, and we refund it in full, from the billing page or by email, no reason needed. After that you can cancel whenever you like and keep your plan until the end of the period you have already paid for. Renewal payments are cancellable rather than refundable.
Yes. An upgrade takes effect straight away and you get the higher allowances immediately. A downgrade takes effect at the end of the period you have already paid for, so nothing you paid for disappears early. You do it yourself from the billing screen.
Yes, and it is not a trial. Free stays free for up to 10,000 visitors a month, with experiments, feature flags, all three statistics engines, commerce metrics, 90 days of data history, and unlimited projects and team members. The AI copilot and assistant are the one thing it leaves out. No card to start, and no expiry date to watch.
No. Free and Pro are entirely self-serve: you sign up, subscribe, change your plan and cancel it yourself, and your invoices are there to download. There is no contract to sign and no minimum term. Enterprise is the only plan that involves a conversation, because its volume and terms are agreed with you.
Pay yearly and you pay for ten months instead of twelve, so it is 2 months free. On the first rung that is $1,490 for the year instead of $1,788. You are charged once for the year, and the visitor allowance is still counted month by month, exactly as it is on monthly billing.
Every plan includes every core feature. Your traffic sets the price, and nothing here is a trial.
