OpenCode - AI coding agent

OpenCode is an open source AI coding agent that helps developers write, modify, and debug code through natural language in the terminal, desktop app, or IDE. With over 195,000 GitHub stars, 950+ contributors, and more than 16 million monthly developers, it is one of the most popular open source AI coding tools today.

Key Features

• Multi-platform: Available as a terminal interface (TUI), desktop app (macOS, Windows, Linux), and IDE extension;
• LSP enabled: Automatically loads the right Language Server Protocols for the LLM to improve code understanding;
• Parallel multi-session: Run multiple agents on the same project simultaneously for independent tasks;
• Session sharing: Share a link to any session for collaboration, debugging, and review;
• Any model: 75+ LLM providers via Models.dev, including Claude, GPT, Gemini, and local models, plus free built-in models;
• Subscription reuse: Log in with GitHub Copilot or ChatGPT Plus/Pro accounts without extra cost;
• Privacy first: Stores none of your code or context data, suitable for privacy-sensitive environments;
• OpenCode Zen: Access handpicked, benchmark-tested models optimized for coding agents.
