The robots.txt generator works like this: it builds a valid robots.txt from your sitemap URL, disallowed paths, crawl-delay and per-crawler blocks. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.
How to use the Robots.txt Generator
Enter the full URL, domain or content the tool asks for.
Run the check - fetch-based tools query the page server-side.
Read the findings as a list, not a single score.
Fix one issue at a time and re-run to verify.

Privacy
The URL you check is fetched once so the tool can read pages that block cross-origin browser requests. No browsing history is stored, and nothing from your own device is transmitted.
Frequently asked questions
Does robots.txt hide pages from Google?
Blocking crawling is not blocking indexing - a blocked URL can still appear in results from links elsewhere. Use noindex meta tags for true de-indexing.
What should a minimal robots.txt contain?
Your sitemap URL and any genuinely off-limits paths - the generator builds exactly that, with per-crawler blocks available when specific bots need different rules.
