Configarr
Configuration sync tool for Sonarr, Radarr, and other Arr apps

Configarr is an open-source configuration management and synchronization tool for the Arr ecosystem, focused on keeping Sonarr and Radarr settings consistent across instances. It syncs TRaSH Guides content and your own YAML-defined configuration to automate setup and ongoing updates.
Key Features
- Single YAML-based configuration to manage multiple Arr applications
- Sync TRaSH Guides-defined Custom Formats and related configuration
- Supports Recyclarr-compatible templates for easier migration and reuse
- Merge strategy for configuration sources: TRaSH Guides, local files, then inline config
- Supports additional, community-provided Custom Formats beyond TRaSH Guides
- Secret and dynamic value injection via custom YAML tags (secret/env/file)
- Container-friendly deployment (Docker) and Kubernetes-ready workflows
- Official support scope: Sonarr v4 and Radarr v5 (others are experimental)
Use Cases
- Standardize Custom Formats and Quality Profiles across multiple Sonarr/Radarr instances
- Keep an existing media automation stack aligned with TRaSH Guides updates
- Manage a multi-app Arr setup (including experimental apps) from a single config
Limitations and Considerations
- Officially supported versions are Sonarr v4 and Radarr v5; other Arr integrations are experimental and may change
Configarr is well-suited for homelab and server setups where repeatability and consistency of Arr configuration matters. It reduces manual configuration work while keeping media automation settings up to date and reproducible.
