OpenCode

About

OpenCode is an open source AI coding agent that helps you write and run code with any AI model. It is available as a terminal interface, a desktop app, or an IDE extension, and you can start multiple agents in parallel on the same project. It includes a set of free models that you can use without creating an account. You can also log in with your GitHub Copilot or ChatGPT Plus/Pro account, or connect any of the 75+ LLM providers available through Models.dev, including local models.

OpenCode is free to use. Connecting other providers may incur additional costs. According to its website, OpenCode does not store your code or context data, so it can be used in privacy-sensitive environments. Its source code is public on GitHub under the MIT License, so anyone can use, modify, or contribute to it.

The project has over 220,000 GitHub stars and 950 contributors, and the website says it is used by over 16 million developers every month. Users who want models that OpenCode has tested for coding agents can use Zen, which the site describes as a handpicked set of benchmarked models.
