Keystroke
Also known as: Buster, buster.so, keystroke.ai
Buster was an open source AI data analyst and data engineering agent that answered analytics questions, built dashboards and maintained dbt models through pull requests. Its founders have pivoted to Keystroke, a platform for building internal agents, and buster.so now redirects to keystroke.ai.
Buster, a Y Combinator W24 company, built an open source AI native data platform: an agent that answered analytics questions and built dashboards, and a data engineering agent that worked on dbt models, schemas and pipelines and opened pull requests with its changes.
In July 2026 its founders launched Keystroke, which their launch post describes as "a recent pivot from Buster, our original YC W24 idea". As of 28 September 2026 buster.so answers with a redirect to keystroke.ai, and the vendor's own Buster repository on GitHub returns 404. Keystroke presents itself as a platform for building internal agents and workflows in TypeScript, with integrations, schedules, webhooks and event triggers, human review steps and a CLI. The Buster data analyst is no longer published by the vendor.
