opencode: Work with an Open Source AI Coding Agent

Overview

OpenCode is an open source AI coding agent for software development. It provides a terminal-based way to work with an AI agent, with a full-access build agent for development and a read-only plan agent for exploring code and planning changes.

It suits developers looking for an agent they can install through familiar package managers or use as a beta desktop app. The project also includes a general subagent for complex searches and multistep tasks.

Key Features

• Terminal UI for working with the coding agent.
• Built-in build agent with full access for development work.
• Read-only plan agent for analysis and code exploration, with permission prompts before bash commands.
• General subagent for complex searches and multistep tasks, invokable with @general.
• Desktop app in beta for macOS, Windows, and Linux.
• Multiple installation routes, including npm, Homebrew, Scoop, and an install script.
• Documentation covering agent configuration and use.

Use Cases

• Developers can use the build agent while carrying out coding work.
• Engineers joining an unfamiliar codebase can use the read-only plan agent to explore before making changes.
• Teams planning a change can use the plan agent to analyze code while keeping edits disabled by default.
• Users who prefer a graphical interface can try the beta desktop app instead of the terminal UI.

Getting Started

Install the latest release with the install script:

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

See the README and documentation for package manager options, configuration, and usage details.

Alternatives

• DeepSeek-Reasonix: DeepSeek-Reasonix emphasizes persistent, long-running terminal sessions and prefix-cache stability, rather than OpenCode’s build and read-only plan agents.
• Grok Build: Grok Build is a full-screen terminal coding agent centered on the xAI ecosystem, while OpenCode also offers desktop apps in beta.
• zero: Zero is a Go-based agent focused on scriptable use, local sessions, and explicit side-effect controls; OpenCode is a TypeScript agent with a terminal UI and desktop apps in beta.
• goose: Goose is a Rust-based extensible agent with a desktop app, CLI, and API, while OpenCode emphasizes build and read-only plan agents.

Considerations

The desktop application is marked beta, so it may be less mature than the command-line option. The build agent has full access, while the plan agent is read-only by default and asks permission before running bash commands. Review the project documentation and agent settings to understand permissions before use.
