Your own WhatsApp bridge — now with WhatsApp calls

The local bridges that ran inside the tjena!chat app are retired. They only worked on one device and the app had to keep running. The Signal bridge inside the app is gone too.

The new tjena Bridge app runs the WhatsApp bridge on a spare Android phone that stays at home.

Announcement

tjena!chat goes live

We are excited to announce the official launch of tjena!chat — our messaging service built on the open Matrix protocol.

What is tjena!chat?

tjena!chat is a privacy-first messenger built on the Matrix protocol. That means your messages are end-to-end encrypted, your account belongs to you — and you can connect with users on any other Matrix server worldwide.
