OpenCode

OpenCode is an open source AI coding agent built in TypeScript. It provides a terminal-based interface for AI-assisted software development with support for multiple LLM providers.

Key Features

• Multi-agent system - Switch between build (full-access) and plan (read-only) agents
• Provider agnostic - Works with Claude, OpenAI, Google, or local models
• LSP integration - Built-in Language Server Protocol support
• Terminal-first UI - Rich TUI experience designed by neovim users
• Client/server architecture - Run locally or drive remotely
• Desktop app - Cross-platform GUI application (Beta)

Installation

# Quick install
curl -fsSL https://opencode.ai/install | bash

# Package managers
npm i -g opencode-ai@latest
brew install anomalyco/tap/opencode
scoop install opencode  # Windows

For desktop app:

# Download from releases or use package managers
brew install --cask opencode-desktop  # macOS
scoop install extras/opencode-desktop  # Windows

Basic Usage

# Start OpenCode in current directory
opencode

# Use Tab to switch between agents:
# - build: full development access
# - plan: read-only analysis

# Invoke general agent for complex tasks
@general analyze this codebase structure

The build agent handles file editing and execution, while plan agent provides read-only analysis and asks permission for bash commands.
