opencode is an open-source AI coding agent built for the terminal. It features a native TUI, multi-session support, and is model-agnostic, letting you use Claude, OpenAI, Google, or even local models.
I’ve just tried out opencodes zen recently, it’s one of the simplest and fastest setups I’ve come across in a while, for working with LLMs in the terminal. The "TUI" feels super clean and intuitive, no fussing around, just install, configure and start using it. (waiting for its support on the Bun runtime though)
opencode now integrates with vscode, cursor, windsurf, etc
it'll be aware of what file you're in and you can easily send inject selected lines into the prompt
start opencode inside your editor and it'll install the extension
Tried opencode and it seems to be super responsive and smart without being intrusive. I love that I can plug in any model I want. It actually feels like coding with a helpful partner in the terminal.
