Goose
Agentic AI Foundation (Linux Foundation)
Goose is a general-purpose open-source AI agent that runs on your machine via CLI and desktop app. Originally built by Block (Square, Cash App), now under the Linux Foundation's Agentic AI Foundation. Goes beyond coding — handles research, writing, automation, data analysis, and complex workflows. Supports 15+ providers (Anthropic, OpenAI, Google, Ollama, Azure, Bedrock) and has deep MCP extensibility.
Free and open source (Apache-2.0). You pay only for LLM API tokens (BYOK) or use existing Claude/ChatGPT/Gemini subscriptions via ACP.
