Comet is a production-grade Stremio add-on (and Kodi plugin) that functions as a high-performance torrent and debrid streaming proxy. It aggregates torrent metadata from 15+ indexers (Torrentio, Jackett, Prowlarr, Nyaa, DMM, etc.), caches results intelligently, and optionally shares discovered metadata across a custom P2P network (CometNet). The architecture is a FastAPI web server with multiple background workers for proactive scraping, metadata enrichment (TMDB, Kitsu, Cinemeta), debrid account syncing, and automated DMM hashlist ingestion. It provides a built-in streaming proxy with per-IP bandwidth controls, an admin dashboard for monitoring and control, and integrates with Prowlarr/Radarr/Sonarr via Torznab. The codebase is well-structured with comprehensive test coverage, Pydantic validation throughout, async-first patterns, and a clean scraper abstraction layer. It is actively maintained with frequent commits and a mature feature set, though the CometNet P2P component remains experimental and some external scrapers may be fragile due to Cloudflare protections.
