8 best AB Tasty alternatives in 2026

Kirro, VWO, and Convert are the strongest AB Tasty alternatives for most teams. But the best pick depends on your budget, your team size, and how much setup you’re willing to do.

One thing you should know before reading any other “AB Tasty alternatives” article: AB Tasty and VWO merged in January 2026. That changes everything. Most competitor lists were written before the deal and haven’t been updated. Ours has.

We compared eight tools below with real pricing, honest drawbacks, and a decision framework to match you to the right one. For the full picture, check our A/B testing tools guide or our VWO vs Optimizely comparison.

Why teams are leaving AB Tasty

AB Tasty doesn’t publish its pricing. You have to book a sales call just to get a number. When you do, the floor is around $40,000 to $60,000 per year. The average contract? $45,134, according to Vendr. We wrote a full AB Tasty pricing breakdown if you want the detailed numbers.

That’s a lot of money for a tool you can’t even try before buying. There’s no free trial.

The product itself is solid for enterprise teams. It has a 4.4/5 rating on G2 with 400+ reviews. People like the visual editor and the support team. But the complaints paint a different picture for smaller teams. Slow loading times. No native Salesforce integration. Reporting that requires workarounds. And a learning curve that gets steep fast.

Then there’s the merger. In January 2026, private equity firm Everstone Capital combined VWO and AB Tasty. The combined entity makes over $100 million a year. VWO’s co-founder Sparsh Gupta became CEO. AB Tasty’s co-founder moved to a sales role.

VWO already killed its free plan after its PE acquisition. Pricing goes up, product direction changes, support gets restructured. If you’re evaluating AB Tasty today, you’re evaluating a company mid-transformation.

Our take: The merger is the biggest reason to shop around right now. Nobody knows what the combined product will look like in 12 months. If you’re signing a new annual contract, that’s a real risk.

Here’s each one in detail.

The 8 best AB Tasty alternatives for A/B testing

1. Kirro: best for small teams that want CRO guidance built in

Most A/B testing tools hand you a blank canvas and say “go test something.” That’s fine if you already know what to test. Most people don’t.

Kirro takes a different approach. It analyzes your site, suggests what to test and why, and learns from every result so the next suggestion is smarter. Think of it as having a CRO consultant built into the tool.

Pricing: EUR 149/month, flat. Unlimited tests, unlimited visitors. No per-visitor pricing that punishes you for growing. No sales call required.

What’s good:

• AI-powered test suggestions based on proven CRO frameworks
• Visual editor for non-technical teams
• 9KB script (one of the lightest in the market)
• Works with GA4 and GTM out of the box
• Math that works with less traffic (Bayesian statistics), so smaller sites can still get useful results

What’s not:

• New to the market, so fewer integrations than established tools
• Not built for enterprise feature flagging or server-side testing

Best for: Solo founders, small marketing teams, and anyone spending under $200/month who wants AI-guided A/B testing that tells them what to test. You can set up your first test in about three minutes.

2. VWO: best all-in-one CRO suite (now merging with AB Tasty)

Recommending VWO as an AB Tasty alternative is weird now. The two companies are the same company.

After the January 2026 merger, they operate under one roof. 4,000+ customers, ~$120 million in combined revenue. If you’re looking for VWO alternatives too, that’s worth knowing.

That said, VWO’s product is genuinely strong right now. It bundles heatmaps, session recordings, surveys, and A/B testing into one platform. You don’t need four separate tools.

Pricing: From $299/month for the testing module. Heatmaps and recordings are separate add-ons. Full suite gets expensive quickly.

What’s good:

• Everything in one place: testing, heatmaps, session recordings, surveys
• Good visual editor with decent template library
• Solid documentation and onboarding

What’s not:

• You’re buying into a company mid-merger. Product roadmap is uncertain.
• VWO already killed its free plan after PE involvement. Prices may rise.
• Module-based pricing adds up fast

Best for: Mid-market teams ($500+/month budget) who want CRO tools bundled together and are comfortable with some uncertainty about the platform’s direction.

3. Optimizely: best for enterprise teams with engineering support

Optimizely is the biggest name in enterprise testing. Over $400 million a year in revenue. Most of that comes from customers buying the whole suite: CMS, commerce, and marketing automation on top of testing.

For our full breakdown, see our Optimizely alternatives guide and Optimizely pricing analysis.

Pricing: Custom, starting around $36,000/year. Some verified G2 reviewers report renewals jumping to $66K+ with bundled products.

What’s good:

• Feature flags that let you turn features on for some visitors and off for others
• Built-in collision prevention so multiple tests don’t interfere with each other (called mutex groups)
• Forrester ranked it #1 for experience optimization in Q4 2024
• Best-suited for running hundreds of concurrent tests

What’s not:

• Requires developers for most setup and configuration
• Pricing is aggressive and unpredictable at renewal. Budget surprises are common.
• The platform has expanded into CMS and commerce, so A/B testing sometimes feels like a side dish rather than the main course

Best for: Enterprise teams (100+ employees) with dedicated engineering resources and budgets above $30K/year.

4. Kameleoon: best for personalization-heavy programs

Nobody talks about Kameleoon, and that’s kind of the point. It’s French-origin like AB Tasty, but it leans harder into personalization and server-side testing (testing that happens behind the scenes, not in the browser). Quiet tool, loyal user base.

Pricing: Custom. Community reports range from $495/month to $90,000+/year. Same “book a demo” wall as AB Tasty.

What’s good:

• Strong server-side SDK for developer teams
• AI Copilot that suggests audience segments for personalization
• Built in the EU with GDPR compliance baked in
• 9.5/10 support rating on G2 (one of the highest in the category)

What’s not:

• Same pricing opacity problem as AB Tasty
• Smaller market share means fewer community resources and third-party integrations
• Complex setup for anything beyond basic testing

Best for: Mid-market to enterprise teams that care deeply about personalization and privacy, especially in Europe.

5. Convert: best for privacy-first teams

Convert has been around since 2008. It’s bootstrapped (no investors, no PE money), profitable, and focused. That independence matters more now than ever.

We covered the full platform in our Convert A/B testing review.

Pricing: From $299/month. Transparent pricing on their website. No sales call required for the base plan.

What’s good:

• No third-party data sharing. Period. Your test data stays yours.
• Bootstrapped and profitable. No acquisition risk.
• Flicker-free testing with strong anti-flicker technology
• Good A/B testing software for teams that care about GDPR compliance

What’s not:

• No built-in heatmaps or session recordings. You’ll need a separate tool.
• Visual editor is functional but not as polished as VWO’s
• Limited AI features compared to newer tools

Best for: Teams where privacy is non-negotiable (healthcare, finance, EU-based companies) and budget is $300+/month.

Our take: Convert is the safest long-term bet in this list. Bootstrapped, profitable, independent. While everyone else is merging and getting acquired, Convert just keeps doing its thing. That stability is worth something.

6. GrowthBook: best free option for developer teams

GrowthBook is open-source and free. It connects directly to your data warehouse (the big database where your company stores all its analytics). That means no data leaves your infrastructure.

If your team has developers who are comfortable with code, GrowthBook gives you serious testing infrastructure for zero dollars.

Pricing: Free (self-hosted) or from $75/month (cloud-hosted). Enterprise plans available.

What’s good:

• Free and open-source
• Connects directly to your data warehouse (Snowflake, BigQuery, Redshift, etc.) so test results use your own data, not a copy
• Feature flags built in. Turn features on for some visitors and off for others.
• Active open-source community

What’s not:

• No visual editor. Every test requires code.
• Requires engineering ownership. Marketing teams can’t run this independently.
• Self-hosted means you manage the infrastructure

Best for: Developer-led startups who want full control over their testing infrastructure. If you’re looking for AB Tasty alternatives for startups and have engineers available, GrowthBook is the free option. Check our A/B testing tools roundup for more.

7. Statsig (now Amplitude): best for data-heavy product teams

Statsig’s story is wild. OpenAI acquired it for $1.1 billion in September 2025. Then in May 2026, the Statsig platform was transferred to Amplitude. So the tool exists, but it lives under new ownership now.

The product is built for teams running lots of tests with large data volumes. It has math that filters out noise in your data (called CUPED variance reduction). You get reliable results faster, with less traffic. It also analyzes results as data comes in (sequential testing) instead of making you wait until a fixed deadline.

Pricing: Free tier (up to 1 million events/month). Paid plans start around $150/month.

What’s good:

• Free tier is genuinely useful for small teams
• Advanced statistics that bigger tools charge tens of thousands for
• Built for teams running dozens of tests per month
• Strong feature flagging

What’s not:

• No visual editor. Developers only.
• Two acquisitions in one year. Platform stability is a question mark.
• Documentation assumes you know statistics

Best for: Product and engineering teams at growth-stage companies who run dozens of tests per month and want advanced stats without the enterprise price tag.

8. Mida: best lightweight alternative for speed-obsessed teams

Mida is built around one idea: your testing tool shouldn’t slow down your website. Its script is just 15KB. For comparison, some tools load 100KB+ of JavaScript before your page even starts rendering.

That matters more than most people realize. An independent benchmark found that testing tools can add 474ms to over 2,000ms of delay. Your testing tool is supposed to help conversions, not tank them.

Pricing: From $299/month ($399 if paying monthly). 14-day free trial.

What’s good:

• 15KB script, fastest in the category
• AI-powered test suggestions
• Good visual editor for marketing teams
• Fast setup, no developer needed

What’s not:

• Newer tool, smaller customer base
• Limited integrations compared to established platforms
• No server-side testing or feature flags

Best for: Marketing teams who care deeply about page speed and want a simple, fast tool without the complexity of enterprise platforms.

The experimentation consolidation wave

If you’re evaluating AB Tasty alternatives for experimentation right now, you need to understand what’s happening in the market. The big players are merging. Prices usually go up when that happens.

Here’s what went down in the last year:

• OpenAI acquired Statsig for $1.1 billion (September 2025), then transferred the platform to Amplitude (May 2026)
• Datadog acquired Eppo for $220 million (May 2025) and launched Datadog Experiments
• Everstone Capital merged VWO and AB Tasty into a $100M+ revenue entity (January 2026)
• Braze acquired OfferFit (personalization/testing)
• Monetate merged with SiteSpect (enterprise testing)

A/B testing is now a $1.5 billion market growing at ~11% per year. That kind of money attracts buyers. Convert wrote a good breakdown of what happens when tools get absorbed into bigger platforms: the original product focus gets diluted. Features you liked become “legacy.” Prices go up.

So if you want a tool that’ll still be the same tool in two years, look at who owns it. Kirro, Convert, and GrowthBook are independently owned. No investor pressure to pivot. No merger roadmap to worry about.

The market went from ~230 to 271 tools in the optimization category between 2023 and 2024. More choice, but also more noise. If you’re coming from Google Optimize and still haven’t settled on a replacement, the market looks nothing like it did two years ago.

How to choose the right AB Tasty alternative for your team

Forget feature matrices. Here’s how to actually pick, based on your situation:

Solo founder or tiny startup (under $200/month): Your best AB Tasty alternatives for startups are Kirro (EUR 149/month, AI tells you what to test) or GrowthBook (free, but you need a developer). If you have under 10,000 monthly visitors, you want a tool with math that works with small traffic. Kirro uses Bayesian statistics for exactly this reason.

Small marketing team ($200 to $500/month): Kirro, Convert, or Mida. All three have visual editors, transparent pricing, and don’t require developer help. Convert wins on privacy. Mida wins on speed. Kirro wins on CRO guidance and recommendations. If you also need heatmaps alongside testing, our Crazy Egg alternatives for heatmaps guide covers tools that bundle both.

Mid-market team with developers ($500 to $3,000/month): VWO or Kameleoon. Both have strong feature sets for teams that can invest time in setup. VWO gives you the all-in-one suite. Kameleoon is better for personalization. Just know that VWO’s future is tied to the AB Tasty merger.

Enterprise ($3,000+/month): Optimizely or Kameleoon. At this level, you need approval workflows, test-collision prevention, and compliance features. Both deliver. Optimizely has the bigger ecosystem. Kameleoon has stronger EU privacy credentials. Adobe Target is another enterprise contender if you’re already in Adobe’s world. Our guide on how Adobe Target compares covers the real costs and trade-offs.

Small and medium businesses are adopting A/B testing faster than enterprise (15.8% growth vs the industry average). But most tools still price and build for big companies first. That mismatch is exactly why tools like Kirro exist.

What to watch out for when switching from AB Tasty

Check your contract first. AB Tasty uses annual contracts with traffic caps. Check your renewal date. Some teams have been surprised by auto-renewals with price increases.

Your old tests don’t transfer. No A/B testing tool offers a way to move tests from one platform to another. You’ll recreate them manually. The upside: it’s a good excuse to clean up and only rebuild the tests that actually matter.

Watch script performance. Testing tools add weight to your pages. Anti-flicker snippets (code that hides the page briefly while the test loads) can increase your page load time by 122%. DebugBear measured a jump from 2.7 seconds to 6 seconds. That’s not subtle.

One thing most “alternatives” articles skip: if your testing tool runs in the browser (client-side testing), ad blockers can mess with it. Some practitioners report a 22% gap between test data and reality. AB Tasty’s own docs acknowledge this mismatch with Google Analytics. Worth knowing before you pick a tool.

Give your team time to adjust. Everything will feel different. The visual editor, the reporting, how results are displayed. Budget a week for your team to get comfortable. Don’t switch tools the day before a major launch.
