6 free alternatives to GrowthBook

DevCycle's free plan includes unlimited seats, unlimited feature flags, all integrations, debugging tools, A/B testing, an MCP server, flag schemas, and custom property schemas. The main free quota is 1,000 client-side MAUs, so it gives teams more room to collaborate than GrowthBook's 3-user cap while still covering core flagging and testing workflows. It is a better fit if your immediate problem is team size rather than warehouse-native analytics. It falls short on project-style breadth because the free plan is centered on feature management rather than the combined experimentation and product analytics setup GrowthBook supports. Switch if you need more collaborators on a flagging-first tool.

• Beats GrowthBook: Unlimited seats instead of 3 users.
• Falls short: No warehouse-native product analytics layer like GrowthBook's.
• Who should switch: Switch to DevCycle if the blocker is GrowthBook's 3-user cap and you mainly need feature flags and A/B tests.

Abby's free Starter plan includes 1,000 events per month, 1 A/B test, up to 3 feature flags or remote configs, and up to 5 environments. For very small flagging setups, that gives you a clear, simple cap structure with environment support and type-safe remote config workflows. It beats GrowthBook on environments, since GrowthBook's free tier does not state an environment count and Abby explicitly includes 5. It falls short on scale because its free tier is tightly capped on events, flags, and tests, while GrowthBook keeps flags, experiments, and traffic unlimited. Choose Abby if you want a small, environment-rich starter plan rather than broader free volume.

• Beats GrowthBook: Up to 5 environments on the free plan.
• Falls short: Only 1,000 events, 3 flags or configs, and 1 A/B test.
• Who should switch: Switch to Abby if you need a tiny but structured flag and remote config setup with multiple environments.

LaunchDarkly's free tier includes unlimited seats, unlimited feature flags, 30 idiomatic SDKs, A/B tests and experiments, 5 service connections, 1,000 client-side MAU, 100,000 experimentation MAU, 30-day account history, API access, integrations, SSO, 2FA, and audit logs. The free bundle is broader than GrowthBook's in collaboration and governance, especially for teams that want more users and stronger release controls. It loses on warehouse-native analytics because GrowthBook is built around a company data warehouse and includes product analytics in the same product. Move here if release management and governance matter more than warehouse-connected analysis.

• Beats GrowthBook: Unlimited seats plus more governance and release controls.
• Falls short: No warehouse-native product analytics focus like GrowthBook.
• Who should switch: Switch to LaunchDarkly if you need feature flag governance for a larger team and can live without warehouse-native analytics.

PostHog's free plan includes 1 project, 1-year data retention, unlimited team members, community support, 1 million product analytics events per month, 5,000 session replay recordings per month, 1 million feature flag requests per month, 1,500 survey responses per month, 1 million managed warehouse rows per month, free historical warehouse syncs, error tracking, logs, workflows, and AI credits. It beats GrowthBook on the breadth of free product analytics features, especially if you want analytics, replay, flags, and warehouse sync in one place. It falls short on project count because it stays at 1 project, the same as GrowthBook, so it is not the answer if your main issue is workspace scale. Use it when you want a wide free analytics suite.

• Beats GrowthBook: Much broader free product analytics and adjacent tooling.
• Falls short: Still limited to 1 project on the free plan.
• Who should switch: Switch to PostHog if you want the widest free bundle around analytics, replay, flags, and warehouse sync.

Hypertune's free plan includes 1m CDN requests per month, 1m analytics events per month, up to 3 team members, unlimited CDN bandwidth and service connections, unlimited MAUs and MTUs, unlimited environments and projects, unlimited feature flags and experiments, Git-based version control, a flag debugger, integrations with Vercel tools, and Google SSO. It beats GrowthBook on free project count because it allows unlimited projects and environments, which is useful for teams splitting work across many apps or releases. It falls short on card friction because its free tier requires a card, while GrowthBook does not. Pick it if you need more workspace flexibility and do not mind the payment step.

• Beats GrowthBook: Unlimited projects and environments on the free plan.
• Falls short: A card is required for the free tier.
• Who should switch: Switch to Hypertune if project and environment limits are your main pain point and you are okay with card-required signup.

Amplitude's free tier includes 10K monthly tracked users up to 2M events, out-of-the-box analytics and templates, Session Replay, unlimited feature flags, Web Experimentation, AI Feedback, unlimited sources and destinations, and access to community and academy. It is stronger than GrowthBook on analytics breadth for teams that want a polished product analytics suite with experimentation features already bundled in. It falls short on explicit collaboration limits because the provided free-tier details do not state unlimited seats or a higher project count. If your priority is free analytics scale and a broad suite, this is a strong option; if you need clear multi-user workspace expansion, GrowthBook is more explicit.

• Beats GrowthBook: 2M events per month with a broader analytics suite.
• Falls short: GrowthBook is more explicit about users and projects on the free tier.
• Who should switch: Switch to Amplitude if your main need is free product analytics at a larger event volume.
