FeatBit

FeatBit is an open-source feature flag management service designed for developers who want greater control over feature releases. Built with .NET, it offers a robust platform for implementing feature flags in your applications, enabling you to:

1. Ship code safely: Mitigate risks by gradually rolling out new features to a small percentage of users before full deployment. This allows for production testing and instant error recovery without redeployment.

2. Innovate faster: Decouple feature deployment from release, minimizing merge conflicts and allowing for immediate feature activation upon request.

3. Create targeted experiences: Release features to specific user segments and continuously measure their impact on business value.

4. Empower developers: Utilize simple if/else statements to control feature releases, eliminating complex DevOps tasks and allowing developers to directly drive business value.
