OpenCode

OpenCode is the open-source AI coding agent (CLI tool), integrating LLMs like GPT-5 and Claude Sonnet 4 directly into the terminal for fast, context-aware development.

OpenCode is the open-source AI coding agent, built for terminal-first developers who demand speed and privacy. It connects your local files, Git history, and a choice of LLMs (e.g., OpenAI's GPT-5 Nano, Anthropic's Claude Sonnet 4) to execute complex tasks directly from the command line . The tool bypasses IDE and browser dependencies, allowing developers to triage issues, fix errors, or implement features with commands like `opencode fix error in main.go` . With over 26,000 GitHub stars by October 2025, OpenCode delivers a secure, context-aware coding partner that keeps your code local and your workflow efficient .
