Keybase is an open-source messaging application with an intuitive interface that can be used on desktop, mobile, and the web. Its purpose is to create secure chat rooms that are a great alternative to other online chat apps, such as Twitter, Facebook, and even Discord. You can create an account with your Twitter, Facebook, or GitHub account.

It features end-to-end encryption, which means that all of the messages you send will be completely private, even if the person you are messaging is compromised by a hacker. It is also open source, so you can find out more information about it in its source code and in the privacy policy.

If you are interested in creating your own chat room or secure messaging app, you can find the source code on GitHub. You can also find some of the features that it offers, including end-to-end encryption, on their website.

Keybase is the first time end-to-end encryption is integrated into a web browser and browser-based communication app.
