Briar vs Session
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.
Session is a private messaging app built and operated by a global community of privacy experts. It uses Account IDs instead of phone numbers or email addresses for signup, encrypts every message with the Session Protocol (built on libsodium), and routes conversations through onion-routed paths across thousands of community-run nodes so no single server can see both the sender and recipient of a message.
