OpenCode is an open source AI coding agent that runs in your terminal, desktop, or IDE, letting you write and run code with virtually any LLM. It ships with free models out of the box and supports 75+ providers — including Claude, GPT, Gemini, GitHub Copilot, ChatGPT Plus/Pro subscriptions, and local models — while keeping your code and context private.

Key Highlights

• Multi-surface: terminal UI, desktop app (beta), web, and IDE extension from a single agent.
• Agent modes: a full-access build agent, a read-only plan agent for safe exploration, and a general subagent for complex multi-step tasks.
• LSP-aware context loading plus multi-session parallel agents on the same project.
• Privacy first: no code or context stored, with shareable session links for debugging.
• Provider freedom: bring existing subscriptions or connect local models via Models.dev.

Best For

Developers and teams who want a vendor-neutral, privacy-respecting AI coding assistant they can run in the terminal or IDE and point at any model they already pay for.
