Browser torrent streaming sounds simple: choose a release and press play. Underneath, a torrent engine must discover peers and transfer pieces while the browser must decode the container, video and audio formats. Relay separates those jobs so each part has a clear responsibility.

What happens when you choose a release

RELAY Web presents the catalogue and available releases. RELAY Companion, installed on the same Windows computer, performs the torrent connection and prepares the selected media locally. The torrent payload does not pass through PARALLAX servers.

Why some torrents do not play in a browser

A healthy torrent is not automatically a browser-compatible video. MP4 and WebM releases using supported codecs are generally the safest choices. MKV containers, HEVC video and advanced audio formats can fail even when peers and file data are available.

What Companion changes

Companion gives Relay access to a focused local engine without turning the browser into a full torrent client. It improves source verification and keeps networking local, but the final media still has to be understood by the browser. Relay for Windows offers an integrated native path.

A practical setup

Install Companion from the official Relay documentation, start it before opening Relay Web, accept the browser’s local-device request, and choose sources marked as compatible where possible. Visit Support when detection, pairing or playback fails.
