Do you fetch my live robots.txt?

No. Paste it. Fetching would be a backend. This keeps the tool private and cheap.

Google-style longest match. If Allow and Disallow are the same length, Allow wins.

Are wildcards supported?

Yes — * in a path and $ for end-of-path, which Google documents.

What if there is no matching group?

The path is allowed. That matches how crawlers treat an empty file.

Does this replace Search Console?

No. It is a local dry-run before you deploy.
