Broccoli: Open-Source AI Coding Agent for Linear to GitHub PRs

Hacker News •

Broccoli is an open-source coding harness that transforms Linear tickets into reviewable pull requests using Claude and Codex, running entirely on your own Google Cloud infrastructure. The tool was developed by a small team at beSimple, a voice data company, to solve the problem of managing multiple coding tasks across local agent sessions. By executing each task in isolated cloud sandboxes, Broccoli eliminates context switching and laptop dependency while maintaining full data control.

Since deployment, Broccoli has handled 100% of PRs from non-developers and approximately 60% from developers, with more complex features still requiring manual intervention. The system uses webhooks for deployment, supports GCP or Blaxel for sandboxes, and integrates with Linear for project management and GitHub for code hosting. The team open-sourced Broccoli as an alternative to cloud coding agents, believing companies should invest in their own coding infrastructure when development is core to their business.

The project is available on GitHub with comprehensive deployment documentation, including a 30-minute setup process using a single bootstrap script. Broccoli's architecture consists of two Cloud Run workloads over shared Postgres, handling webhook processing and automation execution while storing state in Secret Manager. This approach provides production-grade reliability without third-party control planes.
