Cwtch review
Free, open-source Tor messaging for private peer-to-peer conversations.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Cwtch is a free, open-source messaging app and protocol for privacy-preserving communication. It is designed for people who want peer-to-peer conversations using Tor v3 onion services rather than a conventional centralized messaging service. Official builds are available for Windows, macOS, Linux, and Android. Core capabilities include end-to-end encrypted messaging, local profiles, conversation search, appear-offline mode, and configurable message-history retention.
Its strongest differentiator is the combination of Tor-based routing and peer-to-peer communication. Profiles can be password-encrypted, and encrypted profile exports can be imported on another device. Cwtch also supports direct peer-to-peer file sharing. Optional group messaging uses untrusted servers, while offline delivery supports group messages when recipients are not currently connected. These features make the product more suitable for privacy-focused conversations where control over profile storage, message retention, and communication paths matters.
Cwtch is a focused choice rather than a broad communications suite. Group chat, file sharing, and other capabilities are documented as optional experiments, so users looking for a fully mature collaboration platform may prefer a product centered on established group workflows. The platform range covers Windows, macOS, Linux, and Android, but not iOS. Calls are also outside the verified feature set. Choose Cwtch for free, open-source Tor messaging with encrypted profiles and peer-to-peer features; choose an alternative if iPhone access or voice and video communication is essential.
