Overview
OpenCode is an open-source terminal AI coding assistant designed to provide developers with an elegant terminal programming experience. It supports various LLMs such as Claude, GPT, Gemini, DeepSeek, and offers a beautiful terminal UI, intelligent context management, and multi-session support.
OpenCode's design philosophy is 'Terminal-first, no compromise on experience' — while maintaining the lightweight and efficient nature of the terminal, it provides an interaction experience close to that of an IDE. It supports LSP (Language Server Protocol) to obtain code diagnostic information.
