Welcome to Cwtch!
Cwtch is a decentralized, open-source messaging platform built for privacy, anonymity, and metadata resistance. Unlike traditional messengers, Cwtch doesn't require phone numbers, email addresses, or central servers. All communications are routed through the Tor network and encrypted end-to-end, ensuring that no one—not even the network—can monitor your activity. Cwtch empowers users to create private, secure communication spaces that can't be surveilled or controlled by third parties. Download Cwtch now!
