Keybase is a public key directory that allows bi-directionally linking public keys to social media accounts. This is done with proofs to verify the account actually belongs to a given user. Further features include chat, a file system with public and private contents, and private Git repository hosting. While the client is open-source, the server is not. Keybase was launched 2014-02-14 and had 407,163 users as of 2019-08-22.
There's a signed merkle tree that serves as a public audit log to prevent tampering. This tree could potentially be traversed to replicate the database. Relevant API endpoints are:

A retrieval of the current merkle tree as of March 2023 along with all users referenced therein can be found at keybase.io_user_discovery_202303. The item also contains a recursive crawl of followers and following users starting from • • • . Extracted user lists are available at • • • and • • • , respectively.
Until 2023, Keybase allowed for hosting static websites under
keybase.pub subdomains or custom domains through the Keybase Sites feature. This service was a simple proxy for accessing the
/public/USERNAME directory on the Keybase File System with a Markdown renderer (specifically, the Node.js
marked package in
gfm mode). It was shut down on 2023-03-01.
- On 2020-05-07 Keybase announced they've been acquired by Zoom. Commit activity on the client has significantly dried down since, signalling that the project has gone into maintenance mode.
