How much does OpenCode cost?

OpenCode is open source and includes free models. You can also connect your own model providers or subscriptions, and OpenCode offers Zen, a separate offering with handpicked, benchmarked models for coding agents.

What about data and privacy?

OpenCode is privacy-first: it does not store any of your code or context data, so it can operate in privacy-sensitive environments.

Is OpenCode open source?

Yes. OpenCode is open source, with over 208,000 GitHub stars, 950 contributors, and more than 13,000 commits.

OpenCode — The open source AI coding agent

OpenCode is an open source AI coding agent that helps you write code from your terminal, IDE, or a desktop app. It automatically loads the right language servers (LSPs) for the LLM, supports running multiple agents in parallel on the same project, and lets you share a link to any session for reference or debugging. You can use models included for free or connect models from any provider — including Claude, GPT, and Gemini — plus log in with your GitHub Copilot or ChatGPT Plus/Pro accounts. It works with 75+ LLM providers through Models.dev, including local models.

Key Features

Terminal, desktop, and IDE

Available as a terminal interface, a desktop app, and an IDE extension, so you can use the same agent in whichever environment you code in.

Automatic LSP loading

Automatically loads the right Language Server Protocols (LSPs) for the LLM you are using.

Multi-session parallel agents

Start multiple agents in parallel on the same project.

Shareable session links

Share a link to any session for reference or to debug with others.

Bring any model or subscription

Works with 75+ LLM providers via Models.dev (including local models), and supports logging in with GitHub Copilot or ChatGPT Plus/Pro accounts. Free models are also included.

Privacy-first design

Does not store any of your code or context data, allowing it to operate in privacy-sensitive environments.

Zen curated models

Zen gives access to a handpicked set of AI models tested and benchmarked specifically for coding agents, for consistent performance across providers.

How It Works

Install

Install via a curl one-liner (curl -fsSL https://opencode.ai/v2/install | bash) or through npm, bun, brew, paru, or yay.

Choose a model source

Use the free included models, log in with GitHub Copilot or ChatGPT Plus/Pro, or connect any of 75+ providers from Models.dev, including local models.

Run the agent

Work from the terminal interface, desktop app, or IDE extension; launch multiple parallel agents on the same project and share session links when you need review or debugging help.

Pros & Cons

Pros

Fully open source, with a large community (208K+ GitHub stars, 950 contributors)
Works in three environments: terminal, desktop app, and IDE extension
Model-agnostic: supports 75+ providers including local models, plus free included models
Reuses subscriptions you may already have, like GitHub Copilot and ChatGPT Plus/Pro
Privacy-first: does not store your code or context data
Parallel multi-session support on the same project

Who It's For

Best for

Developers who want an open source AI coding agent in the terminal, IDE, or desktop
Teams and individuals who want to choose their own model provider, including local models
Users who want to leverage existing GitHub Copilot or ChatGPT subscriptions
Privacy-sensitive environments where code and context data must not be stored

Not ideal for

Non-developers looking for a general-purpose chat assistant
Teams that require a fully managed, single-vendor AI coding service with no local setup

Use Cases

Writing and editing code with an AI agent directly in the terminal, IDE, or desktop app

Running multiple AI coding agents in parallel on the same project

Using existing GitHub Copilot or ChatGPT Plus/Pro subscriptions for coding agent work

Working with local models or privacy-sensitive codebases that cannot store code or context data

Sharing an AI coding session with teammates via a link for review or debugging
