A fixed plan, never an overage charge.

Creating a workspace is free: it starts on the Free plan. Paid plans cost €590 to €1,990 per month depending on the number of tested visitors, or €5,900 to €19,900 per year, which is 2 months free. Your invoice never exceeds the plan price.

    To install Probant, check your tracking with an A/A test, and try the editor.

    Not enough yet to conclude a revenue test: one needs 180,876 visitors to detect +10%.

  • Essential

    250,000tested visitors / month

    €590 per monthor €5,900 per year (2 months free)

    For a store that tests continuously, down to revenue per visitor.

    1 revenue test per month that can detect +10%.

  • Growth

    2,000,000tested visitors / month

    €1,990 per monthor €19,900 per year (2 months free)

    To test on all the traffic of an established store, several areas at once, and detect smaller effects.

    11 revenue tests per month that can detect +10%, or 2 that can detect +5%.

  • Agency

    1,000,000tested visitors / month, shared across 3 or more workspaces

    €1,490 per monthor €14,900 per year (2 months free)

    For an agency: a pool of tested visitors shared across its clients’ workspaces, on a single invoice.

    5 revenue tests per month that can detect +10%, or 1 that can detect +5%.

For reference, the demo store makes €2.83 in revenue per visitor. A revenue test there needs 180,876 visitors to detect +10%, or 723,496 for +5%, checkpoints included. Less regular order values need more; concurrent tests share their visitors, who count only once.

Creating a workspace is free: it starts on the Free plan. An agency shares the Agency plan across its clients’ workspaces. Beyond 2,000,000 tested visitors per month, or for several sites: Custom plan, quoted on request, on an annual contract. Contact us

One setting

The number of tested visitors. Every feature is in every plan, and the number of tests you launch in a month doesn’t change the price.

Your invoice never exceeds the plan price.

Volume sets the price.

The price is set in advance. The number of tests you launch in a month doesn’t change it.

Price
A fixed amount based on the volume you choose, paid monthly, or yearly with 2 months free.
Volume
A number of tested visitors per month: each distinct visitor who sees at least one test, personalization, or rollout in progress between the 1st and the end of the month. At 100%, a rollout no longer counts.
Tests
As many tests as you want within that volume, with every product feature.
Trial
A workspace’s first Essential subscription starts with 30 free days, and you can cancel without paying anything.
Overage
There is none: your invoice never exceeds the plan price. Once the volume is reached, your running tests and rollouts continue. A new test starts the following month, or right away with a larger plan.

Billing questions.

How much does Probant cost?

The Free plan (10,000 tested visitors per month) costs nothing. Essential, 250,000 tested visitors per month: €590 per month or €5,900 per year; Growth, 2,000,000 tested visitors per month: €1,990 per month or €19,900 per year. Beyond that, or for several sites: Custom plan, quoted on request, on an annual contract.

What does “no overage” mean?

Your invoice never exceeds the plan price. Once the month’s volume is reached, your running tests and rollouts continue, and your site is not affected. A new test starts the following month, or right away with a larger plan.

What is a tested visitor?

It is the plan’s unit: a distinct visitor who sees, between the 1st and the end of the month, at least one test, a personalization (which always keeps a measured holdout), or a rollout in progress. A rollout that has reached 100% no longer counts.

Is the number of tests limited?

No. Tests are unlimited within the plan’s visitor volume, and a visitor seen by several tests counts only once.

Which features are included?

All of them, in every plan: visual editor, test plan and duration, ideas, metrics and margin, reports, session recordings and click maps, guardrails, rollouts, personalization, feature flags, learnings library, installation and integrations, and team and governance. Database and compute in Amsterdam, with Scaleway, in the European Union.

Can I try it before paying?

Yes. The demo is open without an account, with the data of a fictional store. Creating a workspace is free: it starts on the Free plan. A workspace’s first Essential subscription starts with a 30-day trial; you can cancel during the trial without paying anything.

How does billing work?

You pay for the plan monthly, or yearly with 2 months free. Payment goes through Stripe; invoices and payment method are managed from your workspace’s Billing page.

Can I change plans or cancel?

Yes, from your workspace’s Billing page. A new plan applies as soon as payment is confirmed, with no double billing.

Can I have several workspaces?

Yes, one workspace per site: each keeps its own visitors, tests, and plan. Creating a workspace is free: it starts on the Free plan. One person can own 3 workspaces on the Free plan at most; workspaces on a paid plan, those in an agency pool, and those where you are only a member do not count.

Is there a plan for agencies?

Yes, the Agency plan, for agencies that pay for the tool and include it in their services: 1,000,000 tested visitors per month, shared across the client workspaces the agency owns, from 3 workspaces with no maximum, for €1,490 per month or €14,900 per year. A single invoice, an adjustable cap per workspace so one client can’t use up the pool, and client reports branded with the agency’s name. You subscribe to it from the Billing page of one of your workspaces.

What if my agency doesn’t own my workspace?

You keep your own plan. If your agency gave you a code, enter it on your workspace’s Billing page.

Is the assistant included?

Yes, in every plan, with a daily cap per workspace: 400 requests on a paid plan, 40 on the Free plan.
