What is Goose?

Editorial review
Goose is an open source, locally-run AI agent that automates engineering tasks. Developed by Block (formerly Square), Goose operates autonomously to complete development tasks end-to-end rather than just providing suggestions. It can build projects from scratch, write and execute code, debug failures, and orchestrate complex workflows. With support for any LLM and multiple model configurations, Goose offers flexibility for cost and performance optimization. Available as both desktop app and CLI, with MCP integration for extensibility.

Available on: macOS, Linux, Windows

Goose FAQ

Is Goose free?

Yes, Goose is completely free and open source under the Apache 2.0 license. You only pay for the LLM API calls to your chosen provider (OpenAI, Anthropic, local models, etc.).

Who makes Goose?

Goose is developed and maintained by Block (formerly Square), a financial technology company. It has 359+ contributors and an active open source community.

How is Goose different from Claude Code?

Goose focuses on autonomous task execution - it completes entire workflows end-to-end rather than just suggesting code. It works with any LLM provider, runs locally, and is fully open source. Claude Code is tied to Claude models and requires a subscription.

What LLMs does Goose support?

Goose supports any language model through a bring-your-own-key approach. This includes OpenAI, Anthropic Claude, Google, local models, and more. You can configure multiple models for different tasks to optimize cost and performance.

Can Goose work offline?

Goose runs locally and can work in air-gapped environments when paired with local models. The core agent runs on your machine without requiring cloud connectivity (except for LLM API calls if using cloud providers).
