Developers who are comfortable in a terminal and want an open source coding agent. You should know how to install a CLI tool and, per the docs, configure it.

What can you build with opencode?

Explore an unfamiliar codebase safely with the read-only plan agent. Plan a change to a project before letting an agent edit any files. Hand everyday development tasks to the build agent from your terminal. Delegate complex searches across a codebase to the general subagent.

OpenCode is an AI coding agent. You talk to it in a terminal interface, and it helps with development work such as reading code, planning changes and running commands. A desktop app is also available as a beta.

It ships with two built-in agents you switch between with the Tab key. The build agent has full access and is the default. The plan agent is read-only. It denies file edits by default and asks before running bash commands, which suits exploring code you don't know yet.

There is also a general subagent for complex searches and multistep tasks. OpenCode uses it internally, and you can call it with @general in a message. The README doesn't compare OpenCode with other coding agents. It leaves configuration, such as model providers, to the separate docs site.

What it does

Build and plan agents
Build is the default agent with full access for development work. Plan is read-only and asks permission before running bash commands. Press Tab to switch.
General subagent
A helper for complex searches and multistep tasks. You can invoke it with @general in your messages.
Many ways to install
Use an install script, npm, bun, pnpm, yarn, Homebrew, Scoop, Chocolatey, pacman, mise or nix. The script lets you choose the install directory.
Desktop app (beta)
Downloads exist for macOS (Apple Silicon and Intel), Windows and Linux (.deb, .rpm, .AppImage).

Get started

Install it with the script or your preferred package manager, then run it inside a project folder. Start with the plan agent if you want to look around before allowing edits. Check the docs site for configuration.

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

npm i -g opencode-ai@latest

brew install anomalyco/tap/opencode

Commands are copied from the project's README. Read it on GitHub for the full setup.

Anything better than opencode?

OpenCode is the strongest pick for a provider-neutral, open-source terminal coding agent, with the most stars and strong momentum. Look elsewhere if you want a vendor-backed agent tied to one subscription (Codex, Claude Code) or a minimal, hackable core (Pi).
