Plans and limits

Every account starts on Free. Pro raises the limits and adds the AI agent, the agents' debugging tools over MCP (check_project and get_preview_console), custom share addresses, your own domain, registry components, React Sandbox projects, syncing, and tokens that never expire.

Account → Plan shows the current plan, what it includes and how much of each limit is used; /pricing compares the plans.

A request over a limit is refused with a sentence saying which limit — reaching one never removes anything that already exists.
