carl — privacy-first BitTorrent

clearnet<br>Direct & fast

Connect straight to peers when privacy isn’t the priority. Trackers and DHT fully enabled.

proxied<br>Through a SOCKS5 tunnel

Route every connection over a proxy. DNS resolves remotely with socks5h:// — no leaks.

tor<br>Anonymous by default

Download over Tor and seed as a .onion hidden service. Your IP never appears.

Discover over Nostr<br>Find torrents on a network nobody can seize.

carl searches a decentralized relay network for torrent events (NIP-35) — no central indexer to censor, take down, or log your queries. Publish your own with a keystroke.

Every event is Schnorr-signed — trust what you download.

See exactly which relays each result came from.

Add your own relays over wss:// — one per line.

Anonymous by design<br>Seed without ever revealing where you are.

Turn on Tor and carl seeds as a hidden service: peers reach you over a .onion address while your IP stays invisible. The moment a proxy or Tor is set, DHT and UDP trackers switch off — by design, not as an afterthought.

A live leak-check confirms nothing is escaping the tunnel.

Announce your onion over Nostr — no tracker required.

Routing state is on every row — never buried in a menu.
