Fluxa Desktop

A native desktop media client built on a platform-agnostic Rust core.
Connects to the Stremio addon ecosystem. Runs on Windows, macOS, and Linux.

---

Fluxa Desktop is the desktop counterpart to Fluxa for Android. It browses catalogs, tracks watch history across Trakt / MAL / Simkl, and plays anything the Stremio addon ecosystem exposes — including torrents.

The shell is Tauri 2 + React. All decisions — addon resolution, stream planning, library state, playback policy — live in fluxa-core, a headless Rust library that compiles identically for Android and desktop. The platform layer fulfills effects; Rust never calls the network directly.

Features

• Catalogs & discovery — browse, search, and filter across every installed Stremio addon, with a home feed, genre/category grids, and a calendar of upcoming episodes for what you're watching
• Library — watchlist, continue watching with resume position, and custom collections, with import support for existing lists
• Watch tracking — two-way sync with Trakt, MyAnimeList, and Simkl, with OAuth handled locally via a deep-link redirect (fluxa://oauth/...) — no browser round-trip through a hosted server
• Playback — native libmpv rendering with a custom OS-level surface per platform (Linux/X11, macOS, Windows), subtitle track selection, and direct torrent/magnet playback
• Profiles — multiple local profiles on one install, each with its own library, addons, and sync accounts
• Addons — install and manage Stremio-compatible addons directly, no separate addon server required
• Auto-update — in-app update checks and installation via Tauri's updater plugin

Effect loop

Rust emits typed effects; the platform fulfills them. This keeps fluxa-core portable — no platform-specific code inside Rust.

Frontend  →  invoke('engine_dispatch', action)
          ←  { state, effects: [{ id, type, payload }] }
Frontend  →  runs each effect (HTTP / storage / auth / ...)
          →  invoke('engine_complete', { effectId, result })
          ←  { state, effects: [...] }
