Goose, built by Block (the company behind Square and Cash App), is an open-source agent that runs on your own machine and can plan, write code, execute commands, and iterate on a task with minimal hand-holding.

Why it stands out

Runs locally and openly. Goose is fully open source and executes on your machine, not a hosted black box.
Extensible via MCP. It’s built around the Model Context Protocol, so it can be extended with new tools and integrations.
Built by a company that uses it internally, so it’s shaped by real production engineering workflows, not just demos.

Good for

Engineers who want a fully open-source, locally-run agent they can extend with their own tools via MCP.
