Tuliprox is a production-grade IPTV streaming proxy and DVR system written in Rust, with a WebAssembly frontend in Yew. It aggregates IPTV sources from M3U, Xtream, Stalker, HDHomeRun, and media servers (Plex/Emby/Jellyfin) and presents them as a unified streaming backend via multiple protocols (HLS, Xtream, M3U, HDHomeRun). The system provides advanced features: HLS caching and segment repair, recording with conflict resolution and retention policies, RBAC with per-user connection limits and GeoIP filtering, EPG with smart matching, playlist transformation with a DSL-based mapping engine, and comprehensive notification channels (Discord, Telegram, Slack, etc.). The architecture is modular with many loosely-coupled crates (auth, session, hls, dvr, parser, repository, messaging) sharing a common model crate (`shared`), which enforces type safety and prevents configuration drift between frontend and backend. The frontend is a rich single-page application with real-time dashboards, source/playlist editors, user management, and a setup wizard. The codebase demonstrates high craftsmanship in its custom B+Tree storage engine, HLS state machine, notification channel trait, and frontend form management macros. It is actively maintained with CI/CD, Docker deployment, and clear separation of concerns, though some dependency version pinning and large enum variants indicate areas for cleanup.
