Open source feature flagging and remote config

If you want to control features in your app without deploying new code — turn features on for 10% of users, A/B test a new checkout flow, kill a broken feature instantly — Flagsmith is an open source feature flag platform. Think of it as a remote control panel for your application's behavior.

Open source feature flags and experimentation

If you want to run A/B tests or toggle features on and off without redeploying your app, GrowthBook handles both. Feature flags let you ship code that's off by default and turn it on for specific users.

Open-source feature management platform

If you need to control which users see which features in your app — rolling out to 10% of users first, enabling a feature only for paying customers, killing a broken feature instantly without redeploying — Unleash is a feature flag platform that handles all of that. Think of feature flags as on/off switches for your code that you can flip without shipping new code.
