Posteria

Posteria is a web-based media poster management system for organizing and storing custom posters for movies, TV shows, seasons, and collections. It provides an interface to upload, import, manage, and sync artwork with a Plex Media Server while offering a responsive PWA frontend.

Key Features

• Centralized poster library organized by Movies, TV Shows, Seasons, and Collections
• Import posters from a Plex Media Server and fetch artwork from TMDB, TVDB, Fanart.tv, and Mediux
• Sync updated posters back to Plex and optionally lock updated posters in Plex to prevent overwrites
• Upload posters via local files or direct URLs; supports JPG, JPEG, PNG, and WebP formats
• Installable Progressive Web App (PWA) with mobile-responsive UI and a Poster Wall view
• Scheduled auto-imports and orphaned poster detection to identify unused artwork
• Simple built-in authentication and Docker-friendly deployment with configurable environment variables and volume mounts

Use Cases

• Curate and apply custom posters for a Plex media library across movies, shows, and collections
• Maintain a browsable poster catalog and quickly swap artwork from local files or external metadata providers
• Automate periodic imports from Plex to keep the poster library in sync and detect orphaned posters for cleanup

Limitations and Considerations

• Posteria treats Plex as the source of truth; it is not a backup solution and Plex-origin changes can override Posteria selections
• Authentication is basic (single username/password) and there is no built-in multi-user role management or advanced access controls
• Designed for local/trusted networks; exposing the app publicly without additional VPN/reverse-proxy protections is not recommended

Posteria is a focused tool for media enthusiasts and administrators who want an organized, searchable poster repository integrated with Plex. It emphasizes simple deployment, curated poster management, and automated sync workflows.
