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[1]. Keybase was launched 2014-02-14 and had 407,163 users as of 2019-08-22[2].


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:

Documentation is located here:

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 chris[IAWcite.todayMemWeb]. Extracted user lists are available at[IAWcite.todayMemWeb] and[IAWcite.todayMemWeb], respectively.

Keybase Sites

Until 2023, Keybase allowed for hosting static websites under 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[3]). It was shut down on 2023-03-01.

Vital Signs

  • On 2020-05-07 Keybase announced they've been acquired by Zoom[1]. Commit activity on the client has significantly dried down since[4], signalling that the project has gone into maintenance mode.
