Replane is an open-source, self-hosted platform for feature flags and dynamic configuration. It lets teams change feature toggles, rate limits, and app settings in real-time without redeploying code—updates propagate to connected services in under a second via Server-Sent Events.
Key capabilities include version history with instant rollback, override rules for targeting users by plan/region/percentage, JSON Schema validation, and optional approval workflows. Deploy with a single Docker image using PostgreSQL or built-in SQLite.
Official SDKs available for JavaScript, React, Next.js, Svelte, Python, and .NET. MIT licensed. Also available as a managed cloud service.
