9 Best Optimizely Alternatives for SaaS Teams

The quick answer

Quick answer: Optimizely sells on a custom quote, so the main reason to look elsewhere is a published price or a free start. For web testing with a visual editor, Convert publishes prices from $299 a month and Kameleoon from $495 a month, while Wingify (VWO and AB Tasty, now merged) is the closest like-for-like option at enterprise level. For product experiments, GrowthBook, PostHog and Statsig have free plans, and LaunchDarkly and Amplitude suit teams already using them. Datadog Experiments, formerly Eppo, fits warehouse-first teams on Datadog. Prices are as of November 2026, checked on each vendor's own site.

Why teams look for an Optimizely alternative

Optimizely Experimentation is a capable platform. It covers visual web tests and server-side feature tests, with multivariate tests, bandits and AI agents that help plan tests and read results. Teams usually look elsewhere for one of these reasons:

• No public price: the plans page is a form asking for a custom quote, so you can't budget or start without talking to sales.
• Scope: Optimizely also sells a CMS and other marketing products, which is more platform than a SaaS team that only wants experiments may need.
• Team shape: a small product team may prefer flags, tests and analytics in one tool that engineers can adopt on a free plan.
• Data location: some teams want results calculated in their own warehouse, on the metrics finance already trusts.

Optimizely alternatives compared

1. Wingify (VWO and AB Tasty)

Who it is for: marketing and CRO teams that want the closest match to Optimizely's web testing.

Pricing: Wingify lists Growth, Pro and Enterprise plans for web experimentation, each with a demo and no public price. Free trials are offered.

Strengths: visual and code editor, unlimited experiments and metrics, bandits, rollouts and single-page app support on Growth. Pro adds multivariate and cross-domain testing and guardrail metrics.

Limits: like Optimizely, it needs a sales conversation. VWO and AB Tasty merged in January 2026, so ask how the two products will come together.

2. Convert

Who it is for: mid-market teams that want a serious web testing tool at a price they can see.

Pricing: Convert Experiences starts at $299 a month paid annually or $399 monthly, for 100K tested users a month. Pro is $420 paid annually or $599 monthly at that volume. There is a 15-day free trial.

Strengths: visual editor, default anti-flicker, and a choice of frequentist or Bayesian statistics.

Limits: priced by tested users, so high-traffic sites should run the slider first. It is web-first rather than a feature flag platform.

3. Kameleoon

Who it is for: teams that want to build web tests from a prompt, with room to add product tests later.

Pricing: Kameleoon's plans page offers a 30-day free trial with no card and up to 3 experiments. Starter is from $495 a month for up to 10 experiments and 50,000 visitors a month. Enterprise is custom.

Strengths: sequential testing, holdouts and sample ratio mismatch detection on Starter. Feature experimentation, mobile app testing and bandits are add-ons.

Limits: Starter's experiment cap is low for a busy program, and the agent uses a browser extension.

4. GrowthBook

Who it is for: teams that want open source, self-hosting or warehouse-native analysis.

Pricing: GrowthBook's free Starter covers up to 3 users with unlimited flags, experiments and traffic. The self-hosted plan is free with unlimited users. Pro is $40 per seat a month for up to 30 users.

Strengths: it reads metrics from your warehouse, or a managed warehouse if you have none. Pro adds an AI visual editor and bandits.

Limits: you get the most from it with someone who can define metrics in SQL. SSO and SCIM are on Enterprise.

5. PostHog

Who it is for: product and engineering teams that want one tool for events, replay, flags and tests.

Pricing: experiments are billed with feature flags. The first 1M requests each month are free, then from $0.0001 per request.

Strengths: A/B, A/B/n, holdout, fake door and redirect tests, Bayesian or frequentist analysis, and a visual editor.

Limits: a marketer who only tests landing pages may find it heavy. We cover the wider options in PostHog alternatives.

6. Statsig

Who it is for: product teams running many experiments that want flags and analysis together.

Pricing: Statsig has a free Developer plan with 2M events a month. Pro is $150 a month with 5M events, then $0.05 per 1K events. Warehouse-native deployment and SSO are on Enterprise.

Strengths: Bayesian and frequentist methods, a visual web editor and session replay on one platform.

Limits: Statsig says Amplitude acquired it on May 5, 2026, and the original team stayed at OpenAI. See Statsig alternatives.

7. LaunchDarkly

Who it is for: engineering teams that already release behind LaunchDarkly flags.

Pricing: the Developer plan is $0 with 100K experimentation MAU a month and unlimited seats. Foundation is usage-based, shown as $10 per service connection and $8.33 per 1K client-side MAU. Enterprise is custom.

Strengths: tests run on the same flags you ship with, so there is no second SDK.

Limits: no page editor for marketers. Compare it with others in LaunchDarkly alternatives.

8. Amplitude

Who it is for: teams that already measure their product in Amplitude.

Pricing: the free plan has 2M events a month and limited experiments. Plus starts at $0, and Growth is custom.

Strengths: Amplitude Experiment reuses your existing events and cohorts, with unlimited seats on every plan.

Limits: less compelling if you don't use its analytics. See Amplitude alternatives.

9. Datadog Experiments

Who it is for: teams on Datadog that want results calculated on warehouse metrics.

Pricing: Eppo is now Datadog Experiments. Datadog Feature Flags are free below 1M monthly configuration requests, then $55 per 1M billed annually at the first tier. We could not find a public price for Experiments itself, so ask sales. Datadog offers a 14-day trial.

Strengths: variance reduction, sequential testing and warehouse metrics, next to your monitoring data.

Limits: the fit is strongest if you already run Datadog.

How to choose

• Replacing web tests run by marketers: Convert if you want a published price, Wingify if you need enterprise support, Kameleoon if you like building tests from prompts.
• Replacing feature tests run by engineers: GrowthBook if the warehouse is your source of truth, PostHog if you want analytics in the same tool, Statsig if you run many tests. Our feature flag tools guide helps if flags are the larger need.
• Check migration effort: client-side snippets are quick to swap, but server-side SDK calls have to be changed in code. Run one test on both tools before you cancel a contract, and compare the numbers.

We make PLG OS, an in-app onboarding and engagement product. It is not an A/B testing suite, so it isn't on this list.
