Keybase is a free messaging and file-sharing product for Android, iOS, Linux, macOS, web and Windows. It uses public-key cryptography for private chats and says messages and files are end-to-end encrypted so only users and intended recipients can read them. Private keys stay on users’ devices rather than Keybase’s servers. Users can set timers on sensitive messages in one-to-one chats and team, group and community channels. Teams bring together private chats with multiple channels, file sharing and collaboration on Git. Team chats, files and Git are end-to-end encrypted, and team keys change when someone is removed or revokes a device. Teams and subteams can store up to 100 GB of documents, photos and videos; personal Git repositories have a combined 100 GB limit, and each team gets 100 GB for Git. Keybase also supports public communities and identity proofs involving integrated social networks. The download page describes it as open source, and business admin controls are available. For client bugs, Keybase directs users to run `keybase log send` in a terminal and follow the instructions.
