Frequently Asked Questions

What does robots.txt control?

It tells search-engine crawlers which paths they may or may not request. It's a crawling directive, not a security measure, so use it to manage crawl budget and keep low-value pages out of the index.

Should I include my sitemap?

Yes. Adding a Sitemap line pointing to your XML sitemap helps search engines discover all your important URLs. The generator includes a field for it, and the Sitemap Generator creates the file.

Is Robots.txt Generator free to use?

Yes. Robots.txt Generator is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use Robots.txt Generator?

Absolutely. Robots.txt Generator runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
