Welcome to Replane

Replane is a self-hosted application for managing JSON configuration with version history, instant rollback, realtime updates, and full audit trails.

What is Replane?​

Replane helps you manage application configuration that changes frequently without requiring code deployments. It's perfect for:

  • Feature flags - Toggle features on/off without deploying
  • Operational tuning - Adjust cache TTLs, batch sizes, rate limits in realtime
  • Gradual rollouts - Control percentages or cohorts for new features
  • Incident mitigation - Quickly revert to a known-good configuration
  • Cross-service settings - Share configuration across multiple applications

Key Features​

  • Override Rules - Return different values based on context (user, tier, country, etc.)
  • Version History - Every change creates an append-only snapshot with full audit trail
  • Instant Rollback - Revert to any previous version with one click
  • Realtime Updates - Changes propagate via Server-Sent Events (SSE) with zero polling
  • JSON Schema Validation - Prevent invalid configurations before they're saved
  • Role-Based Access - Maintainer, editor, and viewer roles with API key support
  • Self-Hosted - Run on your infrastructure with full data ownership

Status​

Replane is early but usable. Expect changes to schemas and endpoints before v1.0.
