Overview

OpenCode is an open-source AI coding agent built to give developers full freedom over their AI models and environments. It runs as a terminal application featuring a rich Terminal User Interface (TUI) and provides companion extensions for major code editors like VS Code, Cursor, and JetBrains IDEs.

With native support for a wide variety of AI providers (Anthropic, OpenAI, Google Gemini, Ollama, and local models), OpenCode excels at editing code, navigating file structures, and executing tasks across static web projects.

Key Highlights & Features

• Terminal User Interface (TUI): Beautiful, responsive keyboard-driven interface built with Bubble Tea.
• Multi-Model Flexibility: Connect to OpenAI, Anthropic Claude, Gemini, or self-hosted open-weights models via Ollama.
• Editor Extensions: Seamlessly switch between standalone CLI sessions and embedded editor panels in VS Code or Cursor.
• Non-Interactive Batch Mode: Run one-off scripting tasks via opencode run "..." for CI/CD and automation scripts.
• LSP Code Intelligence: Uses Language Server Protocols to understand project dependencies and syntax rules accurately.

Example Usage with Static Websites

When to Use It

• Developers seeking an open-source, privacy-first alternative to proprietary AI coding tools.
• Those who want to use local or specialized LLMs for code editing without cloud lock-in.
• Teams wanting both a fast terminal agent and editor extension integration.
