Probant vs. Amplitude

Both tools compared point by point, based on Amplitude’s public documentation, accessed November 11, 2026. Every statement about Amplitude links to its source.

57 sources from 27 official pages, accessed November 11, 2026.

What Amplitude offers.

Amplitude connects analytics, feedback, experimentation, and code in one suite.1 The company is listed on Nasdaq; Web Experiment is aimed mainly at marketers.23 Sequential testing is its default method; a t-test and a Bayesian reading are available.45

Probant is for sites that want A/B test verdicts that hold up, with a plan set before launch and guardrails monitored through rollout. It measures what each conversion is worth: the margin on an order, a qualified or signed lead, a paid subscription.

The differences, point by point.

On the left, what Amplitude’s public documentation says, each sentence with its source. On the right, what Probant does. “Not mentioned” means nothing was found in that documentation, which does not prove a feature is missing.

Probant and Amplitude, point by point. Note numbers link to the sources at the bottom of the page.
CriterionAmplitudeProbant
Statistical methodThree methods to choose from: sequential test (default), fixed-horizon t-test, and Bayesian; Thompson Sampling for bandits.45Frequentist, with a sequential plan set before launch: target effect, duration, and checkpoints. The verdict fits in one sentence, with a 95% range. Where to check
PeekingThe default sequential test is an mSPRT (mixture sequential probability ratio test): you can check results and stop early without inflating false positives. Available on all plans.67Decisions are only made at planned checkpoints, with O’Brien-Fleming boundaries: very strict at first, close to the usual threshold at the end. During a rollout, ranges are always valid (mSPRT), so you can check them at any time. Where to check
Traffic split (SRM)SRM is detected by a sequential chi-square test (alpha = 0.01) and notified by email or Slack; the documentation suggests treating the results as suspect but does not describe blocking.8910The traffic split is checked with a chi-square test every time the report is read. If the split is off, the test moves to “blocked” status and no winner is declared. Where to check
GuardrailsYou can declare “guardrail” metrics that must not degrade, but no automatic stop or rollback is documented.1112Guardrail metrics are tracked with their range; a guardrail is only breached if the whole range crosses the limit. A breached guardrail blocks the test’s verdict, stops a running test on its own, and during a rollout moves visitors back to the original automatically. Where to check
Gradual rolloutsRollout by percentage and by segment, with manual rollback; no automatic steps or automatic rollback on metric degradation are documented.1314Steps of 25% → 50% → 100% by default, 10% → 25% → 50% → 100% in cautious mode. Automatic rollback when a guardrail is breached; an exposed visitor stays exposed in the following steps. Where to check
Multi-armed banditMulti-armed bandits with Thompson Sampling and hourly, daily, or weekly reallocation; a paid option on the Growth and Enterprise plans.151617Optimization test: Thompson sampling, reallocated at most once a day, with a minimum share per variant. It maximizes a conversion rate, or an amount per visitor such as revenue: purchase probability and average order value drawn from their distributions, with values capped at a percentile as in an A/B test. Optionally, shares per device (mobile, tablet, desktop): one draw per device, each with its own learning and floor. A visitor always keeps their variant: a new split only applies to visitors who arrive after it. The screen says so: it maximizes conversions (or the amount per visitor) during the test, without proving that a variant is better. The difference is read period by period (and device by device), with no declared winner; the CSV export gives the same reading. Where to check
Revenue and margin per visitorRevenue metrics (average order value, revenue per user) through “sum” or “property average,” with a confidence interval on the lift.181920 Margin per visitor is not mentioned in their public documentation (as of November 11, 2026).Revenue and margin per visitor, each with its range; the gain is stated in euros. Margin is calculated on the server from reconciled orders, the cost of each product (Shopify or CSV), and store fees; no margin verdict below 90% of revenue covered by known costs. Where to check
Winner’s curseA quality check flags suspicious lifts (“suspiciously high uplift detection”).21 A winner’s curse correction is not mentioned in their public documentation (as of November 11, 2026).The reported gain is corrected for the winner’s curse by Bayesian shrinkage toward the effects of the store’s past tests. Where to check
Bayesian modeBayesian mode with a Beta(1,1) or non-informative normal prior, custom priors per metric, probability to beat control and to be best, and expected loss control.222324Optional, off by default: a Bayesian reading next to the verdict, with the probability that the variant does better, the credible interval, and the expected loss of each choice. The prior is centered on zero and as wide as the effects measured by the store’s completed tests; while there are too few of them to estimate it, the Bayesian reading is not shown. The decision always follows the sealed plan; when the two readings disagree, the report explains why. Where to check
Multiple comparisonsBonferroni correction on by default, applied to the number of variants and of primary/secondary metrics; it is off in Bayesian mode.252627Segment comparisons are corrected with the Holm method. With several variants, the error risk is split across comparisons (Bonferroni). Where to check
Multivariate testingThe product page mentions multivariate tests; the documentation describes A/B/n tests, and a factorial design or interaction report is not mentioned.28Full factorial design generated by Probant: two to four sections, each with two to four levels, up to sixteen combinations, each served as a variant. Main effects of each section across all traffic and interactions between two sections, corrected with the Holm method on the comparisons stated in the plan. Based on the workspace’s measured traffic, the plan says whether the test can reach a conclusion and suggests removing a level or a section; no best combination is declared without a check. Where to check
Variance reduction (CUPED)CUPED is available on all plans; it is not supported in Bayesian mode or, by default, for retention.29303132CUPED applied to live test reports, using each visitor’s history before their first exposure; without history, the difference stays unadjusted and the report says so. Where to check
Visual editorVisual editor on all plans, which loads the site with an overlay (the script must be installed; blocked by ad blockers). The custom code editor is limited to the Growth and Enterprise plans.333435Two ways to edit, producing the same changes: a page preview loaded by Probant, without its scripts, or the live page on the site, scripts included. On the site, the editor is loaded by the script already installed, through a short-lived signed link for one draft and one variant, with no browser extension. It only sends the chosen changes to Probant. Where to check
WidgetsLibrary of ready-made widgets (call-to-action button, banner, banner with button, modal pop-up) that can be customized in the editor and reused. No countdown or social proof is documented.3637Banner, countdown, pop-up, badge, reassurance, action bar, delivery date, social proof, promo code, free shipping, and survey, set up without code in the editor and saved in the workspace library for other tests. A widget is just a set of ordinary changes: escaped text, links over https or to the site, and styles applied without a style attribute, so a strict CSP does not need loosening. The countdown follows the site’s time zone and disappears at the deadline; the pop-in opens on arrival, on exit intent, or after scrolling, closes with the keyboard, and does not reappear during the visit if consent allows. Their small modules only load for visitors in the variant. The delivery date is calculated in the visitor’s browser (cutoff time, business days, public holidays); social proof shows the exact number of purchases received over a rolling week, and only above a threshold. The survey asks up to 8 questions (closed answers, recommendation scale, open question) with conditional logic, on the page or through a link outside the site (email, QR code), based on 70 templates (recommendation, satisfaction, effort, checkout blockers, cancellation, concept test, multi-question surveys…); open answers are redacted before sending (email addresses, phone numbers, cards, IBANs), kept for 180 days, and grouped by theme; each question is read by variant, with its range and response rate, and comparisons across all questions are corrected together; a response through a link is attached to the variant the visitor saw, recalculated by Probant, or stays outside the test. Where to check
Script and flickerSynchronous script placed at the top of the <head> (recommended) or asynchronous with a snippet that hides the page until the changes apply or a timeout expires. Published base size: 79 KB uncompressed, 20 KB compressed.383940Script under 7 KB compressed, loaded asynchronously, that does not hide the page while it loads. Server-side assignment available, for a display with no flicker at all. Where to check
Granular permissionsRoles and permissions per product on Growth; creating and customizing roles (extended RBAC) is limited to the Enterprise plan.41Four fixed roles, plus custom roles the owner builds from a catalog of named permissions: prepare, launch and stop, roll out, approve a launch, write variant JavaScript, manage flags, metrics, margin, members, and keys. No privilege escalation: billing, roles, transfer, and deletion of the workspace stay with the owner; no one can grant more than their own permissions, and an API key cannot exceed its author’s. Where to check
Data hostingChoice between US and EU data centers; the isolated EU data center is hosted by AWS in Frankfurt, and the Web Experiment script has a dedicated EU URL.4243Database and compute in Amsterdam, with Scaleway, in the European Union. Scaleway, which hosts the database and compute, is a French company. Published subprocessor list: Scaleway (Amsterdam, Netherlands (nl-ams region), in the European Union), Brevo (European Union: servers in France and Germany, encrypted backups in Belgium (Google Cloud), according to Brevo), Mistral AI (European Union by default (European API endpoint), according to Mistral), ClickHouse (option not used), Stripe (Contract with Stripe Payments Europe, Ltd. (Ireland); data transferred to Stripe, LLC (United States), according to Stripe), Sentry (European Union: Frankfurt (Germany), including backups, according to Sentry). Depending on the feature used, Mistral may temporarily transfer data outside the European Union to the subprocessors it publishes; its data processing agreement limits these transfers to countries the EU recognizes as adequate, or covers them with standard contractual clauses. Stripe transfers payment data to Stripe, LLC, in the United States, under the Data Privacy Framework and, failing that, standard contractual clauses. Whatever region is chosen, Sentry may keep the data of Probant’s Sentry account (members, settings, audit log, project descriptions) in the United States; reported errors stay in Frankfurt. Where to check
Consent by defaultThe Web Experiment script offers a consent mode (storage and impressions kept in memory until acceptance), but it is off by default. It does not cover analytics, which is handled separately.444546Consent required by default: no cookie, no assignment, and nothing sent before the visitor agrees. Consent given mid-page: the page does not change in front of the visitor; their variant starts on the next page. First-party cookie, lasting 390 days at most, never extended. Where to check
Pricing modelPriced by event volume, unlimited seats: Free, Plus (from $0, no stated overage penalty), Growth, and Enterprise on quote; paid add-ons are a percentage of the plan. One or two active experiments depending on the plan, more with an add-on.4748495051Creating a Probant workspace is free; paid plans cost €590 to €1,990 per month depending on the number of tested visitors (2 months free with annual billing), with no overage charges. Agency plan: 1,000,000 tested visitors per month, shared across client workspaces, from 3 workspaces, for €1,490 per month or €14,900 per year. Where to check
