About

OpenCode is an open-source AI coding agent built by the SST team (github.com/sst/opencode), MIT-licensed and hosted at opencode.ai. With 197K+ GitHub stars and 950+ contributors, it is the most-starred open-source coding agent. It is fully model-agnostic, supporting 75+ LLM providers including Anthropic Claude, OpenAI, Google Gemini, Amazon Bedrock, Groq, OpenRouter, and local Ollama models. OpenCode runs in three surfaces: a terminal TUI built on the in-house OpenTUI framework, a desktop app (Beta) for macOS, Windows and Linux, and IDE integration. It ships two agent modes — Build mode (full read/write file access and command execution) and Plan mode (analysis-only, generates solutions without modifying files) — plus General and Explore subagents. LSP integration feeds real compiler diagnostics back to the model with 25+ built-in language servers. OpenCode also supports MCP, custom agents, plugins, and a client-server architecture for headless automation in GitHub Actions and CI. For users in China, the desktop version works directly without extra setup and bundles free models such as DeepSeek V4 Flash, making it a practical alternative to Claude Code and ChatGPT for everyday coding.
