What does Robots.txt Generator do?
This tool produces a ready-to-use robots.txt starting point: a User-agent rule that applies to all crawlers, an allowance for the whole site, a disallowed path as an example, and a Sitemap line pointing at your domain's sitemap.
robots.txt is a plain-text file placed in a site's root that tells compliant crawlers which parts of the site they may and may not access. It's advisory — a well-behaved crawler honors it, but it is not a security mechanism.
The output is a template you can extend: add more User-agent blocks to target specific crawlers, list the paths you actually want to block, and adjust the Sitemap line if your sitemap lives elsewhere.
Under the hood
How does it work?
The tool takes the first line of your input as the domain and assembles the standard robots.txt structure: a User-agent line, Allow and Disallow rules, and a Sitemap directive using your domain.
Each line of robots.txt is a directive: User-agent names the crawler the following rules apply to (the wildcard * means all crawlers), Allow and Disallow list path prefixes the crawler may or may not request, and Sitemap points to the location of your XML sitemap.
The template is generated in the browser as plain text, ready to copy into a file named robots.txt and upload to your site's root.

Technical information
How the details work
robots.txt uses a simple line-based grammar. User-agent: * begins a rule block applying to all crawlers; subsequent Allow and Disallow lines list path prefixes that are permitted or forbidden. Rules are evaluated per crawler, with the most specific match winning — which is why a broad Disallow can be overridden by a more specific Allow.
The Sitemap directive is not part of the original standard but is widely supported: it tells crawlers where your sitemap lives without needing to discover it.
Two important caveats. First, robots.txt is advisory: it relies on crawlers choosing to comply, so it must never be used to protect private content — that requires real access controls. Second, the file must be placed at the site root (example.com/robots.txt) and be served as text/plain for crawlers to find it.
Privacy & security
Your data stays yours
Your robots.txt is generated entirely in your browser. Nothing is uploaded or stored.
Local processing — files stay in your browser
- Template assembly runs locally — no input is transmitted.
- Nothing is retained after you close the tab.
- The generated file is copied directly from your browser.
- Analytics only record the page visit.
Limitations
What this tool does not do
- Produces a single User-agent (all crawlers) template — targeting specific crawlers requires editing the output.
- Includes one example Disallow rule; you must list the paths you actually want to block.
- robots.txt is advisory, not a security or access-control mechanism.
- No validation that your paths are correct or that the file will be served correctly.
Frequently asked questions
Common questions about Robots.txt Generator
Where should I place robots.txt?
In your site's root, served at example.com/robots.txt. Browsers and crawlers look for it there, and it must be served as a plain text file.
Can I block specific crawlers?
Yes, by editing the generated file: create a separate block with a specific User-agent (for example User-agent: Googlebot) followed by its Allow and Disallow rules. The template uses * to apply to all crawlers.
Does robots.txt actually block access?
No. It's a set of instructions that compliant crawlers choose to follow. Private or sensitive content must be protected with authentication or access controls — never rely on robots.txt for security.
What does the Sitemap line do?
It tells crawlers where your XML sitemap is located so they can find it without manual discovery. Make sure the URL matches where your sitemap is actually served.
Are my inputs private?
Yes. The file is generated locally in your browser and nothing you enter is sent anywhere.
Is robots.txt required for SEO?
Not strictly, but it's good practice. A simple file that allows crawling and points to your sitemap gives crawlers explicit guidance and can speed up discovery of your pages.
