goose

Goose is a local AI agent with full access to your development environment: it writes code, runs commands, and drives your tools using whatever LLM you point it at. Block (the company behind Square and Cash App) built it, then donated it to the Linux Foundation's Agentic AI Foundation, which makes it one of the few coding agents with vendor-neutral governance instead of a single company's roadmap. Apache 2.0, free.

Extensibility is the differentiator. Goose extends through MCP servers, so the same connectors that work with other agents plug in here: Kubernetes, AWS, CI pipelines, whatever your workflow touches. It runs as a CLI or desktop app, and releases land steadily, mostly provider integrations and protocol work, plus a patched command-execution advisory in its review feature earlier this summer.

Use it if you want an open, vendor-neutral agent you can point at any model, including local ones through Ollama. Quality tracks the model: with a frontier model it's impressive, with small local models it struggles on complex tasks.

The catch: giving an agent full terminal access is powerful and risky, so review what it runs, especially destructive commands. And model API costs are the real price. Expect $30-100/mo for daily use unless you go local.
