Popular messaging apps only allow you to talk to users using the same app. However, Prav allows you to talk to all the users on the same network even if they use other apps like Quicksy, Monocles Chat, Dino, Gajim, Monal, and many more. In other words, Prav has no vendor lock-in. Lastly, Prav is a cooperative (in the process of registration) which allows anyone to become a member and vote on decisions, such as the privacy policy or what features should be added.
