The record

Product: Keybase describes itself as secure messaging and file-sharing.
Messaging: Keybase says it uses public-key cryptography so messages stay private and even Keybase cannot read chats.
Groups: Teams are groups that can chat, use files, and collaborate on Git.
File sharing: Keybase says users can store and share group photos, videos, and documents with end-to-end encryption.
Expiring messages: Users can set a timer on sensitive messages; the feature works in one-to-one chats and team, group, and community channels.
Integrations: Keybase says users can connect with public communities from Twitter, Reddit, and elsewhere.
Team security: Keybase’s Teams documentation says team chats, files, and Git are end-to-end encrypted, and that team keys are changed when someone is removed or revokes a device.
Team file limit: Teams and subteams can store up to 100 GB of documents, photos, and videos.
Git limit: Keybase’s encrypted Git announcement says personal repositories have a combined 100 GB limit and each team gets 100 GB.
Free use: Keybase’s Teams launch announcement says existing free offerings would not switch to a paid model and that current use was grandfathered in.
Open source: Keybase’s download page describes the product as open source and links to its source code.
Support: For client bugs, Keybase instructs users to run `keybase log send` in a terminal and follow the instructions.
Encryption: Keybase says messages and files are end-to-end encrypted so only the user and intended recipients can read them.
Teams: Keybase teams support private chats with multiple channels and team file sharing.
