FeatBit is an open-source, self-hosted feature flag platform that empowers developers to manage safe, targeted, and efficient feature releases across traditional and AI-native workflows.

---

🚀 Overview

FeatBit is an enterprise-grade, open-source feature flag management platform designed for self-hosting. It enables teams to ship code safely with progressive rollouts, deliver personalized user experiences through targeting rules, and decouple feature releases from deployments for faster iteration.

Built to rival expensive SaaS solutions like LaunchDarkly, FeatBit drastically reduces infrastructure costs—up to 20× cheaper—while giving full control over data and compliance via self-hosting.

It supports modern development stacks with SDKs for multiple languages and integrates AI tools for enhanced workflows.

• What problem does this project solve? High costs, vendor lock-in, and limited control of proprietary feature flag services; enables safe releases, A/B testing, and experimentation without ongoing SaaS fees.
• Who is it built for? Developers, engineering teams, and organizations needing robust, self-hosted feature management for web, mobile, and AI applications.
• Why did you build it? Founder Beau Hu and the open-source community created it to democratize enterprise-grade feature flagging, making it accessible, cost-effective, and extensible for everyone.
