opencode

The open source AI coding agent for your terminal

github.com/anomalyco/opencode★ 176kopencode.ai

Overview

OpenCode is an open source AI coding agent that works from your terminal. You install it as a command-line tool and use it to explore, write, and change code in your projects.

It ships with two built-in agents you switch between using the Tab key: a full-access build agent for development work, and a read-only plan agent for analysis and code exploration. A general subagent handles complex searches and multistep tasks.

Beyond the terminal, OpenCode also offers a beta desktop application for macOS, Windows, and Linux, so you can use the same agent through a graphical app.

What it does

  • Runs as a terminal-based AI coding agent you install once and use across projects
  • Built-in build agent with full access for hands-on development work
  • Read-only plan agent that denies file edits and asks before running bash commands, good for exploring unfamiliar code
  • General subagent for complex searches and multistep tasks, callable with @general in messages
  • Switch between agents instantly with the Tab key
  • Optional beta desktop app for macOS, Windows, and Linux alongside the CLI

Getting started

OpenCode installs as a command-line tool. You can use the install script, a package manager, or a platform-specific installer, then run it inside any project directory.

Install with the script

The quickest way is the official install script, which picks an install directory automatically.

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

Or install with a package manager

OpenCode is published to npm and several other package managers, so you can use the one that fits your setup.

bashbash
npm i -g opencode-ai@latest   # or bun/pnpm/yarn
brew install anomalyco/tap/opencode  # macOS and Linux
scoop install opencode               # Windows

Switch agents while you work

Once running, press Tab to switch between the build agent (full access) and the plan agent (read-only). Use @general in a message to call the general subagent for complex searches and multistep tasks.

Commands and code are distilled from the project's own documentation — always check the official repo for the latest.

When to use it

  • Writing and editing code in a project directly from the terminal with the full-access build agent
  • Exploring an unfamiliar codebase or planning changes safely with the read-only plan agent
  • Running complex searches and multistep tasks through the general subagent
  • Using the same coding agent through a desktop app on macOS, Windows, or Linux
