Goose is an open-source, extensible AI agent originally built by Block (formerly Square) and recently donated to the Agentic AI Foundation (AAIF) under the Linux Foundation. Written in Rust for performance and reliability, it runs locally and automates complex engineering tasks across 15+ LLM providers — including Anthropic, OpenAI, Google, Mistral, and Ollama for fully local operation. It ships with a desktop app (macOS, Linux, Windows), a CLI, and an API. The AAIF donation in early April 2026 put Goose alongside Anthropic's Model Context Protocol (MCP) and OpenAI's AGENTS.md spec as the foundation's inaugural projects — signaling serious intent to create neutral, vendor-independent governance for agentic AI standards. Block's engineering team cited wanting a "neutral home" for the agent as the open-source agent ecosystem matures. For teams that want an AI agent they can actually trust to run on local hardware without phoning home, Goose is the most mature option currently available. Its Rust architecture gives it a reliability and performance edge over Python-based alternatives, and multi-provider support means you're not locked into any one model vendor.

StepZen (acquired by IBM) auto-generates GraphQL APIs from REST endpoints, databases, and other sources. Declarative approach to API composition.
Reviewer scorecard
“Goose in Rust with 15+ provider support is the most serious open-source AI agent for production engineering work. The AAIF donation gives it long-term credibility — this isn't a side project that'll get abandoned when Block's priorities shift. The desktop app is polished and the CLI is fast.”
“IBM acquisition slowed development. The auto-generation from REST to GraphQL was interesting but the market moved on.”
“Linux Foundation governance sounds stable until you remember how many projects get donated and then slowly starve of contribution. Block was a real engineering sponsor; AAIF is an unknown quantity. Also, Goose competes with Claude Code and Gemini CLI from companies with massive distribution advantages.”
“GraphQL-as-a-service is a solution looking for a larger market. Most teams that want GraphQL can build it.”
“The AAIF move is politically significant. Neutral governance for MCP, AGENTS.md, and Goose under one foundation could become the equivalent of the Apache Software Foundation for the AI agent era. If that happens, Goose is a very early bet on foundational infrastructure.”
“API composition will be important but AI-powered approaches may replace declarative GraphQL generation.”
“The ability to run Goose fully locally with Ollama — no cloud, no data leaving my machine — is the feature that matters for studios handling client IP. Rust performance means it doesn't drag on long creative automation tasks. Solid choice for privacy-sensitive creative workflows.”
