Muonry
What Muonry is
Muonry is a free, open-source coding agent for bringing AI into a developer’s workflow. Its interactive command-line interface accepts natural-language requests and feedback while providing file reading and search, precise patching, shell commands, planning, and interactive shell tools. Work runs in the user’s workspace, and the project says code remains on the user’s machine unless the user chooses otherwise. Users provide API keys for an LLM provider; Groq, Cerebras, and OpenRouter are named options, with Exa available for optional web search. Muonry says secrets are not printed and destructive actions are avoided unless requested. Prompts, decisions, and code are visible for review. The agent can explain actions, show patches, summarize build and test output, and be stopped or continued. The project reports 1,187 Python lines, uses Apache-2.0 licensing, and is designed for modification or extension, including added language or tool support.
Who it suits
Muonry suits developers who want a local coding agent they can inspect, modify, and extend. It also fits users who prefer supplying their own provider keys and keeping code on their machine.
What it does well
- Free and open-source
- Runs locally in the workspace
- Includes terminal and patching tools
- Supports Groq, Cerebras, and OpenRouter
- Prompts and decisions remain visible
What to know first
- Users must provide an LLM provider API key
- Discord and Matrix support are listed as coming soon
Verdict
Muonry offers a small, auditable coding agent with local operation, terminal access, and extensible code. Its provider-key requirement and still-developing community channels are important considerations.
