About FeatBit

FeatBit is an open-source feature flag management platform that developers can host themselves. It helps teams ship code safely by testing in production, releasing to a small share of users first, expanding gradually, and recovering instantly from errors without redeploying. It is written in C# and .NET and released under the MIT license.

Teams control who sees each feature and when, release to specific target users, and run A/B tests and experiments to measure outcomes. Topics list remote configuration, entitlement, release as code, and progressive delivery. SDKs are available for languages including .NET, Python, and TypeScript, and the project provides documentation, a Discord community, and an online demo.

FeatBit suits engineering teams adopting continuous delivery who want an enterprise-style flag system under their own control, as an alternative to commercial platforms such as LaunchDarkly.
