When you click a movie in Stremio, the app queries all installed streaming addons in parallel. Each addon returns a list of streams (e.g., torrent files, magnet links, or direct HTTP URLs). Stremio then displays them, and you pick one. If it’s a torrent, Stremio can stream it directly using its built-in torrent engine (powered by the torrent-stream library) — no waiting for a full download.
