What is Robots.txt Generator?
This utility constructs the standardized plaintext file that acts as the primary instruction manual for automated web crawlers. When search engines or AI scrapers visit a domain, their very first action is to request this file from the root directory to understand which areas they are permitted to index. By structuring specific User-agent rules combined with Disallow directives, you explicitly command compliant bots to ignore private directories, saving server bandwidth and preventing sensitive administrative pages from appearing in public search results.
Why use our free Robots.txt Generator?
Proper crawler management protects your server infrastructure and safeguards your intellectual property.
- Block AI Scrapers Instantly: The interface includes dedicated toggle switches for modern LLM crawlers like GPTBot, ClaudeBot, and CCBot, allowing you to easily opt out of AI training datasets without researching their specific user agent strings.
- Server Load Mitigation: By selecting a specific crawl delay in the advanced settings, you can force aggressive indexing bots to pause between requests, preventing sudden traffic spikes that could degrade site performance.
- Integrated Sitemap Discovery: The tool properly formats your XML sitemap URL at the bottom of the file, guaranteeing that welcome search engines instantly discover your full content hierarchy.
- 100% Local Processing: Your restricted directory paths and server structures are compiled entirely within your browser, ensuring your private administrative URLs are never transmitted over the network.
How to use the Robots.txt Generator
- 1 Define Global Access: Choose whether the default baseline rule for all unknown bots should be to allow or completely refuse access to your domain.
- 2 List Private Directories: Enter the specific folder paths or file extensions you want hidden from search results, placing each rule on a new line.
- 3 Target Specific Crawlers: Open the advanced settings to individually allow or refuse well-known entities like Googlebot, Applebot, or ChatGPT-User.
- 4 Download and Deploy: Save the final plaintext output, name it exactly
robots.txt, and upload it to the root directory of your web server.
Frequently Asked Questions
No. The text compilation happens entirely within your web browser using client-side JavaScript. Your sensitive admin paths and file structures are never sent to a backend server.
Open the advanced settings and set the dropdown to "Refuse" for GPTBot, ChatGPT-User, ClaudeBot, and CCBot. This explicitly instructs those specific crawlers to ignore your domain, preventing your content from being utilized in future large language model training sets.
It must be placed in the highest-level root directory of your website and named in all lowercase. For example, if your domain is example.com, the final output must be accessible directly at example.com/robots.txt, or crawlers will not recognize it.
No, Google no longer observes the crawl-delay command. However, secondary search engines like Bing, Yandex, and various generic marketing crawlers still respect it, making it highly effective for reducing overall server strain.
Yes. You can enter rules like /*.pdf$ into the restricted directories field. Most major search engines understand the asterisk as a wildcard character and the dollar sign as an end-of-URL matcher.
