OpenCode is an open-source AI coding agent that runs as a terminal interface, a desktop application for macOS, Windows, and Linux (in beta), and an IDE extension. It connects to more than 75 LLM providers through Models.dev, including local models, and can sign in with a GitHub Copilot or ChatGPT Plus/Pro account to use those subscriptions; a set of free models is included.
Two built-in agents are switched with the Tab key: build, the default full-access agent for development work, and plan, a read-only agent for analysis and exploration that denies file edits by default and asks before running shell commands. A general subagent handles searches and multistep tasks and can be invoked with @general in a message. OpenCode loads the appropriate language servers for the project automatically, runs multiple sessions in parallel on the same project, and can share a link to any session. It does not store your code or context data.
