Best CRO Tools for 2026: 10 Picks Ranked by What You Need

VWO is the most complete conversion platform in this list because it covers the whole workflow: run A/B, split URL and multivariate tests in the visual editor, watch heatmaps and session recordings to find what to test, then personalize the winning experience for different audiences. The Growth plan includes unlimited experiments, variations and metrics, plus multi-arm bandit campaigns that shift traffic toward the winning variant automatically.

The catch is the price — or rather, the absence of one. VWO publishes no numbers, so every plan is a custom quote based on monthly active users, which means a sales conversation before you can budget. If you want one platform for the full experimentation program and your traffic justifies it, start here; if you want a published price, Convert does the same job with the numbers on the page.

Convert is the pick for teams that want A/B testing without a sales call first. The Growth plan covers A/B, split URL and multivariate tests, plus heatmaps and session recordings, for 100,000 tested users a month — and every price is published on the page, including a slider for higher traffic. The stats engine offers both frequentist and Bayesian analysis, with checks that catch broken tests early.

The trade-off is the entry price: $399 a month on monthly billing is steep for a low-traffic site, and the annual rate of $299 a month still puts it above most tools here. But the pricing is honest — no feature is held back as a paid add-on, and the trial runs 15 days with no credit card. Choose Convert when you want published prices and a full testing toolkit from day one.

Hotjar is the behavior tool most teams start with, and the reason is simple: heatmaps, session replays, funnels and surveys in one login, with a free plan that covers 200,000 monthly sessions. The Growth plan adds AI features that summarize recordings and answer questions about your data, so you spend less time watching sessions and more time fixing what they show.

What Hotjar does not do is run tests. It shows you where visitors struggle, but turning that insight into a winning variant needs an A/B testing tool alongside it — Convert or Plerdy pair well here. Session limits also scale with the plan, so a high-traffic site outgrows Growth faster than the price suggests. Buy Hotjar to find the problem; buy a tester to prove the fix.

Optimizely is the experimentation platform large teams standardize on. Web Experimentation covers A/B, multi-page, feature and server-side tests, with a proprietary Stats Engine that teams trust for the final call, plus real-time personalization and warehouse-native analytics that tie results to the data stack the business already runs.

Everything about the price is a conversation: there are no published numbers, no self-serve checkout and no free trial, only a demo on request. Implementation commonly takes under a month, per G2 reviewers, but complex stacks take longer. Optimizely fits teams running experimentation as a program, not a project; smaller teams get the same A/B testing from VWO or Convert with less process around it.

Unbounce is the landing page builder in this list, and its A/B testing is built in rather than bolted on: build unlimited pages, publish variants and let the tool route traffic until a winner emerges. The Build plan includes 30,000 AI credits for generating copy and page variants, free hosting, and publishing to your own domain or WordPress.

The limits matter. Build caps traffic at 20,000 visitors a month and includes one user and one root domain, so teams and agencies move up the ladder quickly, and overage fees apply when pages exceed the cap. Unbounce is the right pick when paid traffic lands on campaign pages you control; it is the wrong pick when the pages you need to test live inside your main site.

Crazy Egg is the cheapest way into heatmaps and recordings that still feels like a real tool: $29 a month on the Starter plan, with unlimited websites and team members, no overage charges, and AI analysis for heatmaps and recordings included. The free plan covers web analytics, heatmaps and surveys, so a small site can start without paying anything.

Read the plan table before you buy. A/B testing only starts on Plus at $99 a month — Starter covers heatmaps and recordings only — and every plan is billed annually, so there is no month-to-month option. For a small business that wants to see where visitors click and watch a few recordings, Starter is enough; for testing, Plerdy costs less and includes it on the free plan.

Lucky Orange suits ecommerce stores because it bundles the whole behavior toolkit — dynamic heatmaps, session recordings, conversion funnels, surveys and live chat — in one subscription, and every feature is available on every plan. Only the session limits change as you move up, so there is no feature ladder to climb, and unlimited team members are included throughout.

The entry plan is small: Build covers 3,500 monthly sessions, so a growing store moves to Grow or Expand quickly, and the Discovery AI assistant is a paid add-on rather than included. The 7-day free trial opens every feature on every plan, which is the honest way to test it. Pick Lucky Orange when you want one behavior tool for a store; pick Hotjar when you want deeper AI summaries.

Plerdy is the value pick in this list because it bundles more tools than any other low-cost option: heatmaps, video sessions, pop-ups, ecommerce tracking, conversions, an SEO audit and unlimited A/B testing, from $21 a month billed annually. The A/B testing has no limits on the free plan either — no cap on page views, sessions or test count — which no other tool here offers.

The trade-off is polish. Reviewers say the dashboard can feel overwhelming at first, with many tools and reports to learn, and the Startup plan caps heatmaps at 500 a day and video sessions at 5,000. For a small site that wants one cheap subscription instead of three, Plerdy is hard to beat; for a team that wants a calmer interface, Hotjar or Crazy Egg cost a little more.

Microsoft Clarity is free forever, with no traffic limits and no paid version to upgrade to — unlimited heatmaps, session recordings, websites and team members. Rage click and dead click insights flag frustration automatically, Copilot summaries turn long session lists into readable takeaways, and the Google Analytics integration connects behavior to the traffic numbers teams already watch.

Free has limits. Clarity does not run A/B tests, has no funnels and no ecommerce tracking, so it watches behavior without ever proving a fix — pair it with Plerdy's free A/B testing for a complete zero-cost stack. Reporting is also less customizable than the paid tools, and Microsoft uses the data to improve its own AI products. For any site on any budget, Clarity is the first tool to install.

Fullstory is the deep-analytics tool in this list: session replay with search so powerful you can find sessions by almost any event, funnels and heatmaps, mobile app analytics, and StoryAI summaries that turn large sets of sessions into readable takeaways. It is built for product and UX teams that need to understand behavior at scale, not just watch a few recordings.

The price is the problem for smaller teams: Fullstory publishes no numbers, quotes are built per account, and reviewers note costs can climb as usage grows. The free plan covers 30,000 sessions a month, which is enough to evaluate it properly. Choose Fullstory when session search and AI summaries matter more than price; choose Hotjar or Clarity when they do not.
