Free robots.txt Generator
Free robots.txt, no signup
A free robots.txt generator turns a one-line description of your website, SaaS, WordPress blog, or Shopify store into a complete, correctly formatted robots.txt in seconds, without creating an account. You tell Kamran what your site is and what you want to block or allow, and he hands back a ready-to-paste file with a wildcard User-agent block covering sensible Disallow paths, a Sitemap directive pointing to your XML sitemap, and a commented block for AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot) you can uncomment to opt out of AI training on your content. He applies platform-specific defaults without being asked: WordPress gets the correct wp-admin block with admin-ajax.php allowed so WordPress functionality stays intact; Shopify gets the cart, checkout, and faceted-search paths blocked. He is straight about the limit: robots.txt is a request to well-behaved crawlers, not a security control, and bad actors ignore it entirely, so never use it to protect sensitive data. He flags the deindexing trap on every file: a bad Disallow on / wipes your site from Google overnight, so always test in Google Search Console before uploading. There is no signup and no credit card to start, and when generating one file at a time gets old, the same technical-SEO specialist can become a full AI employee that handles your crawl configuration and site indexability for real.

How it works
- Describe your site: The platform (WordPress, Shopify, SaaS, or other), what you want to block, and whether to restrict AI crawlers. A line or two is enough.
- Get a ready-to-paste robots.txt: A complete, correctly formatted file with User-agent blocks, Disallow paths, AI crawler directives, and a Sitemap line, ready to drop into your root directory.
- Test it, then upload it: Replace the Sitemap URL with your real one, test the file in Google Search Console's robots.txt tester, then drop it into your site root.
Why robots.txt matters for your site
Crawl control robots.txt tells search engines and AI crawlers which pages to index and which to skip, keeping low-value URLs out of the index and your crawl budget focused on the pages that matter
One mistake a single Disallow: / in the wildcard block tells every crawler to leave your entire site, deindexing every page from Google overnight with no warning, making testing before going live critical

How the ways to create a robots.txt compare
| Option | No signup | Platform defaults | Cost | Speed |
|---|---|---|---|---|
| Copying another site's robots.txt | n/a | May not match your platform | Free | Fast |
| Writing it by hand from docs | n/a | Only if you know the paths | Free | Slow |
| Paid SEO platform generators | Rarely | Good, behind a paywall | Subscription | Minutes |
| This free AI generator | Yes | WordPress, Shopify, SaaS, and AI crawler rules built in | Free | Seconds |
A robots.txt that matches your platform from the first line
The hardest part of writing a robots.txt is knowing which paths to block on your specific platform. A WordPress site needs /wp-admin/ disallowed, but /wp-admin/admin-ajax.php must stay open or AJAX-powered features break. A Shopify store needs the cart, checkout, account pages, and faceted-search URLs blocked to keep crawlers off duplicate and transactional pages. A generic robots.txt copied from another site rarely gets these right.
Describe your platform and the generator applies the correct defaults immediately, with inline comments labeling every block so the file is self-explanatory when you open it six months later.
AI crawler directives for GPTBot, ClaudeBot, and more
Most robots.txt guides were written before AI crawlers existed. GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot (Perplexity), Google-Extended (Google AI training), and CCBot (Common Crawl) all respond to robots.txt opt-out directives if you name them as specific User-agent blocks with Disallow: /. Blocking them prevents your content from being used to train their models without affecting your Google search ranking.
The generator includes a commented AI crawler block by default. If you want to allow AI crawlers, it stays commented out and crawlers index freely. Ask to block any or all of them and the next file activates the right blocks. Opting out of Google-Extended does not affect Googlebot's indexing of your pages.
The deindexing trap and why testing matters
The most dangerous robots.txt mistake is also the most common: a Disallow: / in a User-agent: * block tells every crawler to stay out of the entire site. Google stops indexing every page. Traffic drops to zero. The file was valid, the syntax was correct, but one wrong path wiped the site from search results overnight, with no warning from Google until the ranking data showed up days later.
Every file generated here comes with a reminder to test in Google Search Console's robots.txt tester (under Settings) before uploading. The tester shows exactly which URLs each rule blocks and catches bad Disallow patterns before they do damage. Test, then upload.
How it compares to other robots.txt generators
Most free robots.txt generators spit out a fixed template with a wildcard User-agent block and a handful of common paths, with no platform awareness, no AI crawler rules, and no way to refine or ask questions. You paste the output, hope the paths match your setup, and only find out something is wrong when Google Search Console starts reporting blocked URLs.
This one generates a complete file for your specific platform and talks back. Ask it to add your real sitemap URL, block a specific crawler, switch to Shopify defaults, or add a Crawl-delay for Bingbot, and the next file reflects exactly that. No signup to start, and unlike a one-off tool, the same technical-SEO specialist can carry on as a real AI employee once you are ready.
From one robots.txt to your whole site's crawl health
A robots.txt is the start, not the finish, of crawl management. Once it is live, the real work is checking that Googlebot is reaching your important pages, that no new platform updates introduced blocked paths by accident, and that your crawl budget is being spent on pages that matter rather than filtered or duplicate URLs. That is the part most site owners never get back to.
Here the technical-SEO specialist who wrote your robots.txt can stay on. Once you sign up, the same person becomes a full AI employee in your workspace, auditing your crawl health, fixing indexability issues, and keeping your robots.txt current as your site structure changes, so your technical SEO stays handled instead of sitting on a to-do list.
The short version
- A free robots.txt generator turns a one-line site description into a complete, correctly formatted robots.txt with User-agent blocks, Disallow paths, and a Sitemap directive, with no account and no card to start.
- It includes platform-specific defaults for WordPress (wp-admin with admin-ajax.php allowed), Shopify (cart, checkout, account, sort-by URLs), and generic SaaS, plus a commented AI crawler block for GPTBot, ClaudeBot, PerplexityBot, and Google-Extended.
- robots.txt is a request to well-behaved crawlers, not a security control: bad actors ignore it, and a single wrong Disallow can deindex your whole site, so always test the file in Google Search Console before going live.
- When generating one file at a time gets old, the same technical-SEO specialist can become a full AI employee that manages your crawl configuration, site audits, and indexability across your whole site.
What it does
- A complete, ready-to-paste robots.txt from a one-line site description, in seconds
- Platform-specific defaults for WordPress, Shopify, and generic SaaS built in
- AI crawler directives for GPTBot, ClaudeBot, PerplexityBot, Google-Extended, and CCBot
- Sitemap directive included, with a clear note to replace with your real URL
- Inline comments labeling every block so the file is self-explanatory
- Deindexing trap warning and Search Console test reminder on every output
- Refinements on command: block specific crawlers, add paths, switch platforms

Who it is for
- Getting a correct robots.txt live before a site launch without copying one from another site
- Adding AI crawler opt-out rules to an existing robots.txt for GPTBot, ClaudeBot, or Google-Extended
- Applying the right WordPress wp-admin and Shopify checkout paths without looking them up
- Checking whether a robots.txt rule is blocking the wrong URLs before uploading
- A founder or developer who needs a platform-aware robots.txt quickly before handing it to a developer
Good to know
- It generates and refines the file from what you tell it, but it cannot access your live site, test whether your current robots.txt is working, or verify which URLs Google is actually crawling. Use Google Search Console's URL Inspection or robots.txt tester for that.
- robots.txt is a request to well-behaved crawlers, not a security control. Bad actors and most scrapers ignore it entirely. Never rely on it to protect sensitive content: use authentication instead.
- Always test the generated file in Google Search Console before uploading. A bad Disallow can deindex your whole site, and the damage does not show up in ranking data until days later.
- The more you describe your site structure, platform, and what to block or allow, the more accurate and specific the file. A generic one-word description gets you sensible defaults but not a tailored result.
Questions people ask about robots.txt
Short, direct answers to the questions people search for most when creating or fixing a robots.txt file.
How do I create a robots.txt file?
Create a plain text file named robots.txt and place it at the root of your domain (https://yourdomain.com/robots.txt). At minimum it needs a User-agent line naming the crawler (or * for all crawlers) and a Disallow line for any paths to block, plus a Sitemap line pointing to your XML sitemap. This free generator builds the complete file from a one-line description of your site, with platform defaults and AI crawler rules included. Test it in Google Search Console before uploading.
Is this robots.txt generator free?
Yes. You can generate and refine as many robots.txt files as you want with no signup and no credit card. Because the file comes from an AI technical-SEO specialist rather than a fixed template, you can keep steering: add a path, block a specific crawler, switch to Shopify defaults, add your real sitemap URL. After a number of messages it may ask for your email to save your files and keep going.
What does Disallow mean in robots.txt?
Disallow tells the named crawler not to crawl that path or any URL that starts with it. Disallow: /admin/ blocks /admin/, /admin/users, and everything under it. Disallow: / blocks the entire site. Disallow: (blank) means nothing is blocked for that crawler. You can combine Disallow with Allow to open a specific path inside a blocked folder: a common WordPress pattern is Disallow: /wp-admin/ with Allow: /wp-admin/admin-ajax.php so AJAX features keep working.
Can robots.txt block AI crawlers like GPTBot?
Yes. GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot (Perplexity), Google-Extended (Google AI training), and CCBot (Common Crawl) all respect robots.txt opt-out if you name them with a specific User-agent block and set Disallow: /. This prevents your content from being used to train their models. Blocking them has no effect on your Google search ranking. Opting out of Google-Extended does not affect how Googlebot indexes your pages.
What is the difference between robots.txt and a meta noindex tag?
robots.txt controls whether a crawler can visit a URL at all. A meta noindex tag (placed in the HTML head) tells crawlers to visit the page but not include it in search results. If you Disallow a page in robots.txt, Google cannot read the noindex tag either, so a Disallowed page may still appear in search results if other sites link to it. For pages you want deindexed, use a noindex tag and keep the URL crawlable. Use robots.txt to keep low-value pages off the crawl entirely.
How do I write a robots.txt for WordPress?
The critical path is Disallow: /wp-admin/ with an explicit Allow: /wp-admin/admin-ajax.php on the next line (so WordPress AJAX features stay intact), plus Disallow: /wp-includes/, /wp-content/plugins/, /wp-content/themes/, and /cgi-bin/. Add your XML sitemap URL at the bottom (Sitemap: https://yourdomain.com/sitemap_index.xml if you use Yoast or RankMath). This generator builds that file from a one-word description. Test it in Search Console before uploading, as a bad Disallow can deindex your whole site.
How do I write a robots.txt for Shopify?
Shopify generates a default robots.txt automatically, but you can customize it via the robots.txt.liquid template in your theme code. Key paths to block: /admin, /cart, /orders, /checkouts, /account, /collections/*sort_by* (which creates duplicate filtered pages), and /search. Shopify's sitemap is at /sitemap.xml by default. This generator produces a Shopify-specific file you can paste into your robots.txt.liquid template. Test it in Google Search Console after publishing.
Can a robots.txt file break my site's SEO?
Yes. A bad Disallow: / in a User-agent: * block tells every crawler to leave your entire site, deindexing all your pages from Google. Traffic can drop to near zero and the damage shows up in ranking data days after the file went live. Other dangerous patterns: disallowing your CSS and JS files (which stops Google rendering your pages correctly) or disallowing your sitemap path. Always test your robots.txt in Google Search Console's robots.txt tester before uploading. This generator flags the deindexing risk on every output.
Does robots.txt block bad bots and scrapers?
No. robots.txt is a convention that well-behaved crawlers like Googlebot, Bingbot, and most named AI bots follow voluntarily. Bad actors, scrapers, and malicious bots ignore it. Never use robots.txt to hide sensitive content or protect private data. Use authentication, access controls, or server-level rules for that. robots.txt is a polite request to legitimate crawlers, not a security mechanism.
Where does the robots.txt file go?
It must live at the root of your domain, accessible at https://yourdomain.com/robots.txt. For most hosts, this means placing the file in the root of your public folder (the same level as index.html). For Shopify, it is managed as a robots.txt.liquid template in your theme. For WordPress, it can be placed in the root directory or managed via an SEO plugin like Yoast, which generates it automatically. Google checks this exact URL and no other path.
Frequently asked questions
Is it really free?
Yes. You can generate and refine robots.txt files right now with no signup and no credit card. After a number of messages we may ask for your email to save your files and keep going.
Do I need to sign up?
No. Just describe your site and what you want to block or allow, and get a complete robots.txt immediately. Email is optional and only used to save your files and unlock more messages.
Does it handle WordPress and Shopify defaults?
Yes. Tell it your platform and it applies the correct paths automatically: WordPress gets the wp-admin block with admin-ajax.php allowed, Shopify gets cart, checkout, and faceted-search URLs blocked. No need to look up the paths yourself.
Can it block GPTBot, ClaudeBot, and other AI crawlers?
Yes. Ask to block any or all of GPTBot, ClaudeBot, PerplexityBot, Google-Extended, and CCBot and it adds the correct named User-agent blocks with Disallow: /. Blocking these prevents AI training on your content without affecting your Google search ranking.
What is the Sitemap line for?
The Sitemap directive at the bottom of the file tells crawlers where your XML sitemap is. Google reads it during crawl and uses it to discover your pages faster. The generated file includes a placeholder Sitemap line with a reminder to replace it with your real URL before uploading.
Can a bad robots.txt deindex my site?
Yes. Disallow: / in a User-agent: * block tells Google to stop crawling every page on your site. Rankings drop and the damage does not show in Search Console until days later. Always test in Google Search Console's robots.txt tester before uploading.
Does it block scrapers and bad bots?
No. robots.txt is a convention that well-behaved crawlers follow voluntarily. Scrapers and bad actors ignore it. For real bot protection, use a WAF, rate limiting, or Cloudflare's bot management. robots.txt is crawl guidance for legitimate search engines, not a security tool.
Can I give it my real sitemap URL?
Yes. Tell it your real sitemap URL in any message and the next version of the file replaces the placeholder with your actual URL. Just include it in your request, for example: my sitemap is at https://yourdomain.com/sitemap_index.xml.
What language can I use?
Any. Kamran generates and explains robots.txt files in whatever language you write in, though the robots.txt directives themselves are always in the standard format (User-agent, Disallow, Allow, Sitemap) regardless of language.
Does it remember the file it generated?
Within a session it builds on what you have already generated. To keep your files across visits, save them with your email. If you sign up to keep going, the conversation comes with you into your workspace.
Can it test whether my current robots.txt is working?
Not in this free chat, where it generates and refines files from what you tell it without access to your live site. To test your current robots.txt, use Google Search Console under Settings, then robots.txt Tester, which shows exactly which URLs each rule blocks and whether Googlebot can reach your important pages.
What if I want my whole site's technical SEO handled for me?
When managing crawl configuration one file at a time gets old, you do not have to do it alone. You can hire a team of AI employees to handle your technical SEO, indexability, and crawl health across your whole site and start for free.
