Collie is a local-first, open-source coding agent that runs on your own machine instead of in a cloud tab. It verifies its own work: to fix a bug it writes a reproduction that must fail on the broken code, makes the smallest edit that flips it, and re-runs the check, so a task is only done when the check actually goes green.
Because it runs where you do, it can reach your real environment rather than only editing files — driving your already-logged-in browser, driving native desktop apps, capturing the screen, and taking work from your phone, each of them off by default until you turn it on.
It is model-agnostic: bring your own API key, a subscription, or a fully local model via Ollama. No account, no telemetry.
Yes. Collie is free and open-source software released under the MIT license.
