Show HN: Replane – dynamic config for apps and services with real-time sync MIT

Replane is a self-hosted config manager for feature flags and app settings.

It's a self-hosted config manager with real-time updates via SSE, version history, and instant rollback. Changes propagate in under a second. Override rules let you target by custom properties - evaluated client-side so nothing sensitive leaves your app.

Single Docker image, MIT licensed, works with or without Postgres. SDKs for JS, Python, .NET. https://github.com/replane-dev/replane Would love feedback on the SDK API design and what's missing for your use case.
