Posterizarr is an automated poster-making tool for media server libraries, focused on generating clean, textless artwork and consistent branding across collections. It can fetch artwork from common metadata providers and apply custom overlays and text through a browser-managed workflow.
Key Features
- Web UI to configure settings, monitor activity, and trigger runs
- Supports Plex, Jellyfin, and Emby libraries
- Fetches artwork from multiple sources (including TMDB, TVDB, Fanart.tv, and more)
- Focus on selecting and producing textless images for cleaner libraries
- Custom overlays and optional text to standardize posters across collections
- Kometa-compatible folder structure for asset organization
- Automation integrations to trigger runs from tools like Sonarr, Radarr, and Tautulli
Use Cases
- Standardize poster styles for movies and TV shows across a media server
- Automatically generate collection/series branding with overlays
- Maintain an assets folder for Kometa-managed library customization
Limitations and Considerations
- Best results depend on external metadata/artwork availability and quality
- Requires additional dependencies for image processing in typical setups
Posterizarr is a practical choice for homelab and media-library users who want consistent visuals without manual poster hunting. Its web UI and automation hooks make it suitable for continuous, set-and-forget library curation.
