Free tools for vibe coded websites

Three single-purpose tools for sites built with AI coding tools like Lovable, Cursor, Claude Code, v0 and Bolt. Each one works on any public URL with no account, and each one says what it cannot do.

What they are, and what they are not

They are free because they are small and cheap to run, and because the people who use them are the people IntentGrid is built for. None of them installs anything or changes your site. They fetch your public pages the way a browser would.

The checker makes no model calls at all. The other two use a language model within a shared daily budget, and they tell you when it has run out instead of quietly handing you something worse.
