Tiramisu

Tiramisu is a self-hosted media streaming system built around a custom FUSE virtual filesystem and an embedded BitTorrent engine. Every .mkv it exposes looks like a real file on disk, but every byte is served live from a BitTorrent swarm on demand, with no downloading and no temp files.

The BitTorrent engine runs inside the same OS process as the FUSE layer, connected by an in-memory pipe. When Plex or Jellyfin reads a byte range there is no HTTP round-trip or proxy overhead, just bytes flowing directly from peers through RAM to the media server.

Built in Go as a single binary, it runs on a Raspberry Pi 4 and streams 4K HDR Dolby Vision content, fully seekable, starting in under a second. It persists a permanent inode map to SQLite so Plex and Jellyfin recognize files across restarts, keeping watch history and metadata intact.

A control panel and health monitor dashboard are included, plus a native sync engine and Prowlarr integration for automated torrent discovery.
