Developer Quick Tips
- Set user-agent to * to apply rules to all crawlers, or target Googlebot, Bingbot, or specific agents.
- Add multiple disallow paths one per line to block crawlers from directories, files, or file types.
- Include your sitemap URL so search engines discover all pages faster after deployment.
- Download or copy your generated robots.txt and place it in your site root before going live.
- Review the output format: User-agent, Allow, Disallow lines, blank line, then Sitemap.
Frequently asked questions
How do I create a robots.txt file online?
Enter your user-agent (default *), set your allow path (default /), add disallow paths one per line for directories to block, and include your sitemap URL. The generator builds your robots.txt locally in your browser, which you can copy or download and place in your site root.
Does this robots.txt generator upload my input to a server?
No. This generator runs entirely in your browser. Your user-agent, allow, disallow, and sitemap input never leave your device and are not sent to DevToolMate servers.
Is the robots.txt generator free and do I need an account?
Yes, it is completely free with no account or login required. Generate and download as many robots.txt files as you need.
What is the correct format for disallow rules in robots.txt?
Each disallow rule blocks a path from crawlers. For example, Disallow: /admin blocks the admin folder, and Disallow: *.pdf blocks PDF files. The generator formats these automatically as separate Disallow directives.
Can I test how search engines will interpret my robots.txt file?
This generator creates your robots.txt file locally but does not validate crawler behavior. After deployment, use Google Search Console or Bing Webmaster Tools to test your robots.txt rules.
Will my robots.txt input persist after I close the browser?
No. Your input stays in memory only while the page is open. Closing the tab clears all tool input. Your theme preference is stored locally but is separate from tool data.
