Threema Web is the official browser-based web client for Threema, a privacy-focused end-to-end encrypted mobile messenger. It mirrors the mobile app to the desktop over WebRTC or encrypted WebSockets using SaltyRTC signaling, keeping all data end-to-end encrypted.

Use cases

  • use threema messenger from a desktop browser
  • mirror my phone's encrypted chats to my computer
  • self-host a web client for threema
  • send and receive threema messages without my phone in hand
  • run a privacy-focused web messenger client in docker

When to choose

  • you use Threema and want to chat from a desktop browser
  • you want end-to-end encryption preserved on the web client
  • you prefer self-hosting the web client via the official Docker image

When to avoid

  • you need a native desktop app with new features - development is in maintenance mode pending Threema for Desktop 2.0
  • you don't use Threema - this client only works with a paired Threema mobile app
  • you want a general-purpose chat framework to build on
