Open beta

This is an open beta

  • Anyone can sign up. It runs on a single server, so expect the occasional outage.
  • Your apps keep working as before. chateverything is one more linked device, and it catches up when it is back.
  • Things will change, and some will break along the way.

Under the hood

How it works

For the curious: the path a message takes, from your phone to this inbox. Open-source parts, each doing one job.

  1. Your networks

    WhatsApp, Signal and LinkedIn. Your accounts stay yours; chateverything signs in next to your phone.

  2. Bridges

    One bridge per network signs in for you, as a linked device on WhatsApp and Signal, and turns every message into a Matrix event.

  3. A Matrix homeserver

    Synapse keeps every message as an event in a room, behind one API for every network. Federation is on, so it talks to other Matrix servers too.

  4. The people index

    chateverything’s own service follows that stream and works out who is who: one person, every network they use. Two contacts are only linked when you confirm it.

  5. The app

    A web app in your browser. Conversations stay separate per network, listed under the person. You log in with a passkey; there are no passwords.

Who can read what

The short version: outsiders can’t, whoever runs the server can.

Encrypted

  • The connection between your devices and the server (HTTPS)
  • The server’s disk, unlocked by hand after every reboot
  • The server’s backups

Not hidden from the server

Messages inside the running server. A bridge has to decrypt a message to translate it, and Matrix end-to-end encryption is not switched on yet. So whoever runs the server can read your chats, as with any service that sorts and searches them for you.

The server is in Amsterdam, at Scaleway.
