SimpleX Chat
Team chatPrivate messaging with no phone numbers or user IDs of any kind.
SimpleX Chat is for people who want private conversations without handing over a phone number or username. It gives users no identifier at all, which makes it hard for servers or outsiders to see who talks to whom. You can use the preset servers or run your own, and still talk to people on other servers.
- Connects people through one-time links or QR codes, not phone numbers.
- Keeps contacts, groups and message history only on your devices.
- Lets you run your own SMP and XFTP relay servers next to the preset ones.
What people use it for
Talk privately without sharing a phone number
Create a chat profile in the app, which stays on your device. Tap the new chat button, create a one-time invitation link and share it, or let your contact scan the QR code. After connecting, compare the connection security code to verify the contact.
Run a small private group
Tap the new chat button, choose Create secret group and invite contacts from your list. Group preferences control disappearing messages, direct messages, deleting for everyone and voice messages. Each message is sent separately to every member, so secret groups suit smaller groups.
Route your team's messages through your own server
Install an SMP server on a Linux server with the installation script or the simplexchat/smp-server Docker image, using your own domain. Copy the full server address, including its password, into the app's server settings, and keep or disable the preset servers. Share the server's QR code so colleagues can receive messages through it too.
