Looking for a secure instant messaging app? Speek.Chat is a free open-source messenger based on Tor hidden network services.

No server, no metadata, no ID or phone number! With it, users are only identified via public keys. By sharing the key to others, they can send request to add you into contact list and then start chatting.

Speek.Chat messenger features:

  • Serverless, no metadata, anonymous.
  • Peer to peer encrypted using TLS/SSLv3, routed via Tor network.
