The problem
Each GitHub issue you fix by hand takes time you would rather spend building.
What it does
Colonizer runs a coding agent on a GitHub issue you choose and hands back a pull request to review.
How it works
- Each agent works in its own isolated VM, away from your machine and your keys
- Runs locally, on your own computer
- Returns ready-to-review pull requests
Free and open source (MIT). Runs on your own machine; nothing is hosted.
Save yourself hours of coding work on every backlog.
TodayWorks today on Linux and macOS (DMG), and on Windows through WSL2 (v0.2.22), with Claude Code as the agent.
The film
Aims
- Autonomous operation
- The backlog is the thing that should clear itself. A person picks the issue and reviews the pull request; everything between (the sandbox, the worktree, the agent, the mesh, the commit and the push) is the automation target.
- Intelligence
- Isolation and judgement rather than a bigger model: one settler per colony, questions returned as multiple-choice cards instead of prose, a watchdog that notices a colony has stopped making progress, and a router that puts the right model on each slot.
- Growth
- Repository-led. Growth is repositories with colonies running and pull requests merged from them, counted from the first install that is not the author’s.
The technical detail
A local-first app that turns GitHub issues into pull requests. Each task gets a coding agent, Claude Code today, inside its own disposable KVM microVM with a fresh git worktree, linked to the host over a private mesh that never touches your own tailnet. The web UI shows the chat, a terminal in the VM and the agent’s questions as multiple-choice cards. The host, not the VM, commits, pushes and opens the pull request, so the GitHub and Claude tokens never enter it. The Rust host, the in-VM daemon and the React UI are open source under MIT and run locally on Linux x86_64 with KVM. There is no hosted service; more coding agents, a model router, remote outposts and GitLab, Linear and Jira sources are planned, not built.
