True freedom in communication
MOSA operates without central servers. Your messages are relayed through a peer-to-peer mesh network, ensuring no single point of failure or control.
The MOSA project is a commercial product of Talivio Technology OÜ. Basic messaging features (like WhatsApp and Telegram) are completely free. However, plugin features (WhatsApp/Telegram bridges, web links, manga view, etc.) are available via a monthly subscription model on App Store and Google Play.
Trust & Security
Automatic protection against suspicious activity
Every contact has a reputation score based on their behavior. Low-trust contacts are automatically flagged.
Contacts with suspicious behavior are automatically blocked. No spam, no attacks.
All security events are logged. Track any suspicious activity in your network.
Even gateway operators cannot read your messages. True privacy by design.
