Iris Messenger

Iris Messenger is like the messaging apps we're used to, but better.

  • No phone number or signup required. Just start using it!
  • Secure: It's open source. Users can validate that big brother doesn't read your messages.
  • Available: It works offline-first and is not dependent on any single centrally managed server. Users can even connect directly to each other.

Use

Browser application: iris.to

Desktop version: (download, source code):

  • Communicate and synchronize with local network peers without Internet access
    • When local peers eventually connect to the Internet, your messages are relayed globally
    • Bluetooth support upcoming
  • Opens to background on login: stay online and get message notifications!
  • More secure and available: no need to open the browser application from a server.

Develop

git clone git@github.com:irislib/iris-messenger.git
cd iris-messenger
yarn
yarn start

The stack is just iris-lib, gun, jquery and some helpers.

Privacy

Messages are end-to-end encrypted, but message timestamps and the number of chats aren't. In a decentralized network this information is potentially available to anyone.

By looking at timestamps in chats, it is possible to guess who are chatting with each other. It is also possible, if not trivial, to find out who are communicating with each other by monitoring data subscriptions on the decentralized database.

In that regard, Iris prioritizes decentralization and availability over perfect privacy.

Profile names, photos and online status are currently public. That can be changed when advanced group permissions are developed.

The application is an unaudited proof-of-concept implementation, so don't use it for security critical purposes.

You can’t perform that action at this time.
