Collie is a local-first, open-source coding agent published by Collie that runs entirely on the user's own machine rather than in a cloud-based environment, currently available in version 0.20.19, the single listed release. Its purpose is to assist with software development tasks while verifying its own work: to fix a bug, the agent writes a reproduction that must fail on the broken code, makes the smallest edit that flips the result, and re-runs the check, so a task is only considered complete when the verification actually passes. This self-verifying workflow makes Collie suitable for use cases such as bug fixing, iterative code editing, and automated development tasks where correctness must be demonstrated rather than assumed. Because the agent operates where the user does, it can reach the real local environment instead of only editing files: it can drive an already-logged-in browser, control native desktop applications, capture the screen, and accept work handed off from a phone. Each of these capabilities is disabled by default and must be explicitly enabled by the user, preserving a conservative security posture. Collie is model-agnostic, meaning it does not lock users into a particular AI provider; users can bring their own API key, use an existing subscription, or run a fully local model through Ollama. The software requires no account and collects no telemetry, aligning with its local-first, privacy-oriented design. Relevant categories for this software include coding agents, AI-assisted development tools, developer utilities, and open-source automation software. Its combination of on-device execution, self-checking behavior, optional control over browsers and desktop apps, and flexible model backends positions it as a development tool for programmers who want an autonomous coding assistant that operates directly within their own environment without depending on cloud infrastructure or external accounts.
