Briar vs SimpleX Chat
Side-by-side comparison of features, pricing, ratings, and alternatives.
Briar is a free, open-source messaging and forums app designed for situations where regular internet access is unreliable or censored. It connects directly with nearby contacts over Bluetooth or Wi-Fi, or routes messages through the Tor network when online, storing all data locally on the device rather than in the cloud. Briar started as an Android-focused app and now also has a Briar Desktop beta for Windows, macOS, and Linux. In mid-2026 the project announced it has entered maintenance mode, meaning it will continue receiving bug and security fixes but is not planned to get major new features, due to funding constraints and long-standing technical challenges like Android battery drain.
SimpleX Chat is an open-source, end-to-end encrypted messenger built around a network design with no persistent user identifiers of any kind, not even random ones. Messages are relayed through servers that see only noise, so there is no phone number, username, or account ID for anyone, including SimpleX, to tie back to a person. The app supports one-to-one and group chats, audio and video calls, file transfer, and multiple chat profiles, and it can run on self-hosted servers for organizations that want full control over their infrastructure. Its protocol and clients are fully open source and have been independently security-audited by Trail of Bits.
