12 Best Tools for Visual A/B Testing in 2026 (Free and Paid, Compared)

VWO is the veteran of this list: it has spent a decade refining the visual editor other tools imitate, and it shows in details like the heatmap and session-recording suite that ships in the same subscription. The Growth plan covers unlimited experiments, variations and metrics, with multi-armed bandit tests, rollout campaigns and a QA assistant that catches broken variants before they reach live traffic. Wingz AI Core, the AI analysis layer, is included on Growth rather than held for the top tier.

The catch is the price — or the lack of one. Since VWO merged with AB Tasty under Wingify in January 2026, every tier is a custom proposal priced by monthly active users, so budgeting means a sales conversation. A free trial account lets you explore a data-rich sandbox before you talk numbers.

Convert Experiences is the dedicated testing platform for teams that want every feature in one subscription and every price on the pricing page. The Growth plan includes the visual and code editors, A/B and split URL tests, heatmaps, session recordings and more than 90 integrations, with SmartInsert anti-flicker so visitors never see a page half-changed. It is also one of only two dedicated testers here that still publishes its full price ladder.

At $399 a month billed monthly — $299 on annual billing — for 100,000 tested users, it is the dearest transparently priced tester in this list, and multivariate testing waits for Pro. But the price buys clarity: no modules, no surprise add-ons, and support that reviewers rate more highly than any other dedicated tester here.

Optimizely is the enterprise standard for experimentation, and it behaves like one: web and full-stack testing, feature flags and server-side experiments live in a single platform with a program-management layer for teams that run dozens of tests at once. The visual editor covers A/B and multivariate tests, split URL tests and multi-armed bandits, while the companion feature-flag product lets product teams ship controlled rollouts through the same system.

Every plan is individually packaged and sold on an annual contract, and third-party reports put Web Experimentation from about $36,000 a year — so this is a budget line, not a checkout. Smaller teams should start with Convert or GrowthBook and graduate to Optimizely when experimentation becomes a company program rather than a marketing project.

AB Tasty built its reputation on a visual editor marketers can use without a developer: a drag-and-drop canvas, a widget library for fast variants, and a statistics engine that runs Bayesian, frequentist and sequential methods side by side. The platform adds personalization, recommendations and feature flags, and EmotionsAI segments visitors by psychological profile rather than just device or source.

Since the January 2026 merger with VWO under Wingify, every plan is a custom proposal priced by traffic, modules and domains, with reported entry prices around €15,000 a year. That puts AB Tasty firmly in enterprise territory — a strong fit for marketing-led teams with real traffic, a poor fit for a first test.

Kameleoon's headline feature is Prompt-Based Experimentation: describe the variant in plain language and the AI builds it, which makes it the fastest route from idea to running test in this list. The Starter plan covers 10 experiments and 50,000 tracked visitors a month, with sequential testing, sample-ratio-mismatch detection and multiple-testing correction built in, plus a Figma integration that turns winners into reusable design files.

At $495 a month it is the dearest published entry price here, and AI experimentation is metered on credits — 30 to 200 a month depending on tier — so heavy AI use costs extra. But for mid-market teams that want a published price and a genuinely different editor, Kameleoon is the most interesting option in the list.

Adobe Target is the testing layer of Adobe Experience Cloud, and its value shows most inside that stack: Analytics metrics become Target reporting metrics, and Experience Manager content drops straight into tests. Standard covers A/B and multivariate tests with Auto-Allocate and rules-based and geographic targeting; Premium adds Auto-Target, Automated Personalization and Recommendations that adapt each visitor's experience in real time.

There is no published price — licensing runs on annual page-view traffic or server calls, quoted inside a wider Adobe agreement — and the learning curve is steep. Buy Adobe Target when your stack is already Adobe; buying it standalone, without Analytics and Experience Manager, wastes most of what the price covers.

Unbounce pairs a drag-and-drop landing-page builder with unlimited A/B testing, which makes it the right pick when the test is the page itself rather than a site-wide change. The Experiment plan adds unlimited pages, popups and sticky bars, dynamic text replacement that matches headlines to ad keywords, and conversion reporting — while AI copywriting, included from Build, writes the variants faster.

The trap is the tier: A/B testing starts on Experiment at $149 a month, and the $99 Build plan cannot test at all, so the headline price misleads. Every plan also caps visitors and bills $80 per extra 10,000 visits. For paid-traffic teams testing campaign pages, though, the builder-plus-tester combination is hard to beat.

Instapage is built for paid-media teams: its server-side A/B testing avoids the flicker client-side tests can show, and AI Experiments route traffic to the winning variant automatically. AdMap maps ad accounts to matching landing pages, and dynamic text replacement swaps headlines to match the search-ad keyword that brought the visitor — small features that add up to a genuinely better post-click experience.

Testing starts on Optimize at $199 a month ($159 on annual billing); the $99 Create plan is a builder only, and heatmaps wait for the custom-priced Convert plan. The 14-day trial also requires a card. If your traffic comes from ads and your pages are the funnel, the Optimize plan earns its price quickly.

Webflow Optimize is the only tool here that runs inside the site builder itself: you design variants in the Webflow Designer, publish, and read results without a separate tool or an extra tag. The entry tier covers 5 concurrent optimizations, and AI Optimize tests combinations of several changed elements at once, while personalization and audience targeting sit in the same add-on.

The price is the catch twice over: $379 a month billed monthly ($299 on annual billing) is an add-on on top of a paid Site plan, and the entry tier covers only 25,000 page views a month. It only makes sense if your site already lives on Webflow — for everyone else, the same money buys a standalone tester with far more traffic.

Zoho PageSense is the cheapest honest visual testing plan in this list, and it hides a full analytics suite behind the price: heatmaps, session recordings, funnels and form analytics all ship with the Optimize plan, alongside A/B and split URL testing and personalization. Native Zoho CRM and Zoho Analytics integrations mean no middleware, and there are no domain restrictions — test across all your sites and subdomains.

The editor is basic next to VWO or Kameleoon, and complex pages can still need a developer. Testing also starts on Optimize at $30 a month — the $16 Analyze and Engage plans cannot test — and pricing scales with visitor volume, so the $30 entry covers 10,000 visitors a month. For small teams in the Zoho ecosystem, though, nothing else comes close on value.

Crazy Egg is the simplest tool here: heatmaps, session recordings, surveys and A/B testing in one dashboard that a non-technical owner can learn in an afternoon. The Plus plan runs unlimited A/B tests with CTAs and error tracking, and hitting a plan limit pauses tracking instead of triggering an overage bill — a small mercy that keeps the budget predictable.

Two things to know before buying: A/B testing starts on Plus at $99 a month, so the $29 Starter plan cannot test, and every plan bills annually only, with no month-to-month option. Testing is also basic — no multivariate or server-side tests — but for small teams that want one easy tool, the combination is hard to beat.

GrowthBook is the only open-source tool in this list, and that changes the economics: self-host it free, or use the free hosted Starter for up to 3 users with unlimited experiments, feature flags and traffic. Pro adds the AI Visual Editor, split URL tests, multi-armed bandits, sequential testing and CUPED variance reduction, with Bayesian and frequentist statistics in the same dashboard.

The visual editor needs Pro at $40 a seat a month — the free Starter tests through code and flags — and full analysis wants a data warehouse, or the managed warehouse add-on. For product and engineering teams that already live in a warehouse, though, GrowthBook is the most capable testing platform that costs nothing to start.
