Good question! while we use CLI agents as the coding backbone, our focus is really on the application building experience: live preview and seamless deployment.
The key difference is that we give you an isolated sandbox container where you can see your app running instantly, then deploy it with one click. so instead of just getting code output, you get a runnable application that you can interact with and ship immediately. openCode is great for pure coding tasks, but we're optimized for the full build-preview-deploy cycle.
