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.
NuvioTV is a full-featured Android TV media player application that aggregates content from Stremio-style addons, debrid services (Real-Debrid, Torbox, Premiumize), and torrent streaming via TorrServer. It provides a rich browsing experience with personalized continue-watching, library management, and cross-device watch progress sync through a Supabase backend. The application deeply integrates with tracking services (Trakt and Simkl) for scrobbling and history, and includes an extensive settings system for theme customization, playback controls, and addon management. Architecturally, it is a single-module Android app built with Kotlin, Jetpack Compose for TV (androidx.tv.material3), Hilt dependency injection, and a custom fork of AndroidX Media3 (ExoPlayer) with native components for Dolby Vision processing, subtitle sanitization, and frame-rate detection. The codebase follows MVVM with ViewModels emitting sealed UI states via StateFlow, and uses DataStore for per-profile preferences. It includes two build flavors (full with plugin runtime and updater, playstore with stripped features) and an extensive test suite covering sync logic, playback policies, and data migrations. The system's complexity lies in its multiple external integrations (addon protocol, debrid APIs, tracking providers, Supabase RPC) and the custom player pipeline that handles codec failover, subtitle merging, and adaptive bitrate control. While the code is generally well-structured with clean abstractions and reusable UI components, it suffers from moderate technical drift due to vendored AndroidX modifications, flavor divergence, and reliance on rapidly evolving third-party APIs.
