About

OpenCode is a free, open-source AI coding agent built by the team behind SST (Serverless Stack) that brings intelligent coding assistance to your terminal, desktop, and IDE. With over 120,000 GitHub stars, 800 contributors, and 5 million monthly developers, it has rapidly become one of the most popular developer tools on GitHub. OpenCode connects to 75+ AI models through Models.dev, including Claude, GPT-4, Gemini, and local models via Ollama, so you are never locked into a single provider. The tool ships with two built-in agents: Build Agent for full-access development work including file edits, command execution, and code generation, and Plan Agent for read-only analysis and code exploration without making changes. What sets OpenCode apart from commercial alternatives like Claude Code, Cursor, and GitHub Copilot is its privacy-first architecture. No code or context data is stored or shared, making it suitable for enterprise and privacy-sensitive environments. The automatic LSP integration connects to language servers for Rust, Swift, TypeScript, Python, Terraform, and more, giving the AI deep understanding of your codebase without manual configuration. OpenCode supports multi-session parallel agents, session sharing via links, and auto-compact conversations when approaching context limits. It stores session history locally via SQLite. Installation takes one command via curl, npm, Homebrew, or Go install. The desktop app is currently in beta for macOS, Windows, and Linux, while IDE extensions work with VS Code and Cursor. For developers who want full control over their AI coding tools without subscription fees, OpenCode delivers a remarkably capable experience at zero cost.
