What is OpenCode?
OpenCode is an open-source AI coding agent that runs entirely in your terminal. Built by the open-source community, it brings AI-powered coding assistance directly to the command line - without needing a GUI editor like VS Code or Cursor.
OpenCode can read your codebase, chat about it intelligently, and make edits across multiple files. It supports multiple AI backends including Claude 3.5 Sonnet, GPT-4o, and even local models via Ollama - giving you full control over which AI you use and the associated costs.
