OpenCode is a fully open-source AI coding agent (MIT License) designed for developers who want deep LLM integration directly in the terminal, desktop app, or IDE. It supports 75+ LLM providers via Models.dev — including Claude, GPT, Gemini, GitHub Copilot, ChatGPT Plus/Pro, xAI, and local models — with free built-in models available through Zen at no cost. Key technical highlights include LSP (Language Server Protocol) support, multi-session parallel agent execution, and a privacy-first architecture that does not store code or context data. With 220,180 GitHub stars, 950 contributors, and 20,000+ commits since its 2025 founding, OpenCode has rapidly become one of the most active open-source AI developer tooling projects.
