OpenCode is an open-source AI coding assistant. It offers various ways to use it, such as a terminal interface, a desktop application, or an IDE extension.
How is it different from Claude Code?
They are functionally similar, with key differences being:
100% open source.
Not tied to a specific provider. While we recommend using models from OpenCode Zen, it can also be used with Claude, OpenAI, Google, or even local models. Model iterations will narrow the differences and reduce costs, so remaining provider-agnostic is important.
Built-in LSP support.
Focus on Terminal User Interface (TUI). OpenCode is built by Neovim enthusiasts and the creators of terminal.shop, and will continue to explore the limits of the terminal.
Client/server architecture. It can run locally while being driven remotely by a mobile device. TUI is just one of many potential clients.
