Briar
What it is
Briar is free messaging software for people who need communication without relying on a central server. Messages synchronize directly between users’ devices. Without Internet access, Briar can sync through Bluetooth, Wi-Fi, or memory cards; with Internet access, it can use the Tor network. The app includes private messaging, public forums, and blogs. Communications between devices are end-to-end encrypted, contact lists are encrypted on each device, and messages are stored locally rather than in the cloud. Briar Mailbox can deliver messages when users are online at different times. Android, Linux, macOS, and Windows versions are available, with Android distributed through Google Play, F-Droid, or direct APK download. Briar Desktop lacks several Android features. The maker says the project is in maintenance mode, with security updates and bug fixes planned.
