Goose

Goose

Goose is an open-source, on-machine AI developer agent from Block (formerly Square), released under Apache 2.0. It runs autonomously in your terminal, executing multi-step coding and DevOps tasks: writing code, running tests, debugging errors, managing files, and calling external APIs — all powered by the LLM of your choice.

Key features

• On-machine execution: reads/writes files, runs shell commands, interacts with the local dev environment
• LLM-agnostic: works with Anthropic Claude, OpenAI GPT-4, Ollama, and other backends
• MCP-compatible — extend with any MCP server (databases, APIs, cloud tools)
• Persistent sessions with memory across tasks
• Safe by design: shows planned actions before execution, supports sandboxing
• Apache-2.0 license
