Stream and download permitted torrents in a clean browser interface. The engine runs on your computer, the address stays predictable, and no cloud torrent backend is required.
$ npx hash-harbor
One command. One local route.
Hash Harbor is not a hosted downloader. The page is served by a native process on your machine, so ordinary BitTorrent peers work without sending the torrent through somebody else’s server.
npx hash-harbor
localhost:3210
Made for the actual file
Metadata, peers, progress, playback, and every file live in one compact interface.
Video and audio get full playback controls. MKV and AVI files can be converted for browser playback when FFmpeg is installed.
The default address is always localhost:3210. Change the port in settings
when you need to—Hash Harbor never silently moves somewhere else.
The macOS background service makes your localhost bookmark available again after a restart, with status and stop commands when you want control.
See peers, transfer speed, received bytes, file count, and useful metadata errors instead of staring at an unexplained zero.
Your machine, your address
Open it in any modern browser, bookmark it, and keep the browser UI separate from the engine doing the transfer. Closing a tab does not move your settings to a remote server.
Quick start
You need Node.js 20 or newer. The launcher selects the right native binary, verifies its checksum, starts Hash Harbor, and opens your browser.
$ npx hash-harbor
$ npx hash-harbor install-service
$ npx hash-harbor status
$ npx hash-harbor config --port 3210
Local does not mean anonymous
Hash Harbor does not include anonymity or a VPN. Use it only for files you have permission to access and share, and apply the same network precautions you would use with any torrent client.
The practical questions
No. The web interface talks to the native engine on your own machine. Torrent traffic still travels between you and peers on the BitTorrent network.
Browser-only clients are limited to WebRTC peers and compatible web seeds. The native engine can use ordinary BitTorrent TCP, UDP, trackers, and DHT, which makes normal magnets much more likely to work.
Hash Harbor validates and saves the new port, restarts its local listener, and redirects your browser. It does not fall back to a random port.
Only for converting formats such as MKV and AVI for browser playback. Torrent metadata, downloads, and browser-native media formats work without it.
Harbor ready
