It's Claude Code Cloud with UI that allow you to use Claude Code outside of CLI

Now in beta as a research preview, you can assign multiple coding tasks to Claude that run on Anthropic-managed cloud infrastructure, perfect for tackling bug backlogs, routine fixes, or parallel development work.

Run coding tasks in parallel

Claude Code on the web lets you kick off coding sessions without opening your terminal. Connect your GitHub repositories, describe what you need, and Claude handles the implementation.

Each session runs in its own isolated environment with real-time progress tracking, and you can actively steer Claude to adjust course as it’s working through tasks.
