Open-source feature flag tool with remote config & A/B testing, deployable via Docker in under a minute.
Core Features
- Feature flags: safely release and rollback features
- Remote config: toggle features without redeploying
- A/B testing: run multivariate tests using segments
- Segments: target specific users or environments
- 15+ SDKs: support for TypeScript, .NET, Java, etc.
What It Can't Do
- •For production, use external PostgreSQL and Redis; default SQLite is not recommended. Free version lacks enterprise governance features; self-hosted upgrades require manual migration—backup regularly.
Use Cases
- Gradual rollouts of new features
- Remote control for marketing campaigns
- A/B testing to optimize conversion
- Beta access for preview features
Detailed Introduction
Flagsmith is an open-source feature flagging and remote configuration tool that helps teams safely roll out features, run A/B tests, and manage releases without deploying new code. It supports 15+ SDKs (TypeScript, .NET, Java, etc.), offers segmentation, organization management, and can be self-hosted or used as SaaS. With a Docker Compose setup, you can start in under a minute. Its BSD-3-Clause license makes it a strong alternative to proprietary solutions like LaunchDarkly.
