FeatBit

FeatBit is an open-source feature flag management and experimentation platform designed to help teams release features safely and run controlled rollouts. It provides a web portal, SDKs for multiple languages, and deployment options for both small and production-scale environments.

Key Features

• Feature flag creation and management with environments and projects
• Targeting rules and user segmentation for controlled exposure
• Progressive rollouts (percentage-based) and fast rollback without redeploying
• Experimentation and A/B testing to measure impact of changes
• Insights and flag usage visibility during rollouts
• IAM features for managing access by project/environment/team
• Audit logs for tracking changes to flags and segments
• Web APIs and webhooks for automation and integrations
• Optional relay proxy/agent to reduce latency or run flags in customer environments

Use Cases

• Gradual release of risky features with quick rollback and minimal operational overhead
• Running A/B tests for product changes and measuring outcomes across user cohorts
• Centralized feature control for multi-environment delivery workflows (dev, staging, prod)

Limitations and Considerations

• Open-core licensing: some enterprise capabilities (for example SSO and certain workflow features) require a commercial license key

FeatBit is a strong fit for teams that want developer-friendly feature toggles plus experimentation in a deployable platform. It supports both quick Docker-based setups and production-oriented deployments with Kubernetes tooling.
