Introduction

OpenCode: The Open Source AI Coding Agent for Terminal

OpenCode is a powerful, open-source AI coding agent designed specifically for the terminal, empowering developers to write, analyze, edit, and execute code with AI assistance directly from the command line. Unlike provider-locked tools, it supports over 75 LLM providers via Models.dev, including popular ones like Anthropic's Claude (with Pro/Max login), OpenAI's GPT, Google's Gemini, and even local models—ensuring flexibility as models evolve and costs drop.

Key Features

Native Terminal UI (TUI): Responsive, themeable interface optimized for terminal users, built by Neovim enthusiasts and creators of terminal.shop. Pairs seamlessly with any IDE/editor, with extensions for VS Code, Cursor, Windsurf, etc.
Built-in Agents: Switch via Tab key between:
- build: Full-access for development (file edits, bash commands).
- plan: Read-only for analysis/exploration (permission-gated edits/commands).
- general (@general): For complex searches/multi-step tasks.
LSP Integration: Auto-loads language servers for accurate completions/context.
Multi-Session & Collaboration: Run parallel agents on projects; share session links for debugging/reference.
Privacy-First: No code/context storage; ideal for enterprise/sensitive envs (/docs/enterprise).
Client/Server Architecture: Run core on machine, control remotely (e.g., mobile); web/desktop (soon) clients.

Installation (One-Liner YOLO)

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

Supports npm, brew, choco, scoop, paru, mise, nix, etc. Custom dirs via env vars.
