Subrosa is an open source, end to end encrypted messaging app. It runs in the browser, and supports voice, video and group chats.

Subrosa's security has been independently audited by Cure53, and it has received 6/7 on EFF's Secure Messaging Scoreboard.

More importantly, Subrosa has been designed to be easy to use. There's no point building secure messaging services if you have no one willing to learn and use it with you. Subrosa is designed to be incredibly accessible so you can use it for everyday conversations with anyone.
