Goose is an open-source AI agent that goes beyond code suggestions: it installs dependencies, runs and tests code, and automates whole engineering workflows from the terminal or its desktop app. Created by Block and now part of the Linux Foundation's Agentic AI Foundation alongside MCP, it is built to be model-agnostic. Add Opper as an OpenAI-compatible provider and it runs on any of 700+ models with one key.
GooseoninPaste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
