All tools Robots.txt Generator ● Live Developer Tools

How Robots.txt Generator works

  1. Add one or more User-agent rules (use * for all crawlers).
  2. Specify Disallow and Allow paths for each user agent.
  3. Add your sitemap URL as a Sitemap directive.
  4. Copy the generated robots.txt and upload it to your site's root.
  • Block crawlers from indexing admin, staging, or search-result pages.
  • Add a sitemap reference to help search engines discover your pages.
  • Set different crawl rules for specific bots (e.g. block an aggressive scraper).
  • Prepare a robots.txt file before launching a new site.
  • Audit and rebuild an existing robots.txt with cleaner rules.

Everything is generated locally in your browser — nothing is uploaded.

  • robots.txt only controls crawling, not indexing — use noindex meta tags to prevent indexing.
  • Not all crawlers respect robots.txt; it's a guideline, not an enforcement mechanism.
  • Doesn't validate the file against your live site structure.

FAQ

Frequently asked questions

Is Robots.txt Generator free to use?

Yes. The tool is free and runs directly in your browser with no account required.

Does this tool upload my data?

No. Processing happens locally in the browser tab. Your input is not sent to a server.

What is this tool best for?

Building a robots.txt file with user-agent rules, disallowed paths, and a sitemap reference before launching or relaunching a site.

Where do I put the generated robots.txt file?

It must be placed at the root of your domain, e.g. https://example.com/robots.txt. It won't be read by crawlers if placed in a subdirectory.

Can robots.txt prevent a page from appearing in search results?

Disallowing a path stops crawling, but a previously indexed page can still appear in search results (e.g. via links) unless it's also blocked with a noindex meta tag or removed via search console tools.

Can I set different rules for different search engines?

Yes. Add separate User-agent blocks (e.g. 'Googlebot', 'Bingbot') each with their own Allow/Disallow rules, or use 'User-agent: *' for all crawlers.

Should I include a sitemap reference?

Yes, adding a 'Sitemap: https://example.com/sitemap.xml' line helps search engines discover your sitemap, though submitting it via search console is also recommended.

What happens if I disallow everything by mistake?

'Disallow: /' under 'User-agent: *' blocks all crawlers from your entire site, which can remove it from search results over time. Double-check rules before publishing.

Is robots.txt required?

No, it's optional. Without one, crawlers assume they can access everything. A robots.txt file is only needed if you want to restrict or guide crawler access.
