AutoBangumi is a fully automated anime download and organization tool. It subscribes to RSS feeds (Mikanani, etc.), downloads torrents via qBittorrent or Aria2, parses release titles to extract episode/metadata, renames and organizes files for media libraries (Plex, Jellyfin), and provides a web UI for management. The backend is a FastAPI application with async SQLite storage, background schedulers, and a multi-provider notification system. The frontend is a Vue 3 + TypeScript single-page app with a custom component library. The architecture employs clean abstraction layers for downloaders, notification providers, and LLM-based title parsing, with a state machine for durable rename operations and a secure online update mechanism. It is a well-engineered application with extensive test coverage (unit, integration, E2E with Playwright) and active development reflected in frequent releases and a robust CI pipeline.
