Featbit

The platform provides a self‑hosted service for managing feature flags, allowing developers to enable or disable functionality at runtime without redeploying code. It supports progressive rollouts, canary releases, and A/B testing, giving teams the ability to expose new features to a small subset of users and expand gradually while monitoring impact. Flags can be targeted to specific users or groups, and the system offers instant rollback in case of errors.

It is built on .NET 8, Python ≥ 3.9, and Angular 19, and ships with Docker‑compose scripts for quick local deployment. Official SDKs are available for multiple languages, enabling simple function calls in application code to evaluate flag states. The service can be run on any infrastructure chosen by the organization, supporting compliance and data‑protection requirements.

The project is released under the MIT license, is listed as open‑source and libre, and includes documentation, community channels, and an online demo. It is positioned for developers who need a reliable, enterprise‑grade feature‑toggle solution that can be hosted and.
