About Cwtch

Cwtch runs each conversation over Tor onion services so there is no account, no phone number and no central server that learns who talks to whom. Groups use servers that participants can run themselves and that cannot read the messages they relay.

Strengths

  • Designed specifically to resist metadata collection, not just message reading
  • No account, phone number or email required

Limitations

  • Tor routing makes delivery slow and requires both parties online
  • Small project with a limited feature set
