Configarr

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.
