Robots.txt Generator —
Create Search Crawler Directives Online

Our free Robots.txt Generator provides a visual editor to build RFC-compliant robots.txt files for websites and web applications. Configure crawler indexing rules for search engine bots (Googlebot, Bingbot, Baiduspider, YandexBot) and enable one-click protection against AI content scrapers (GPTBot, ChatGPT-User, CCBot, ClaudeBot, PerplexityBot). Include line-separated Allow and Disallow directory paths, XML sitemap index locations, and Crawl-delay rate limits. Choose from pre-configured presets (Standard SEO, Strict Private, Block AI Crawlers, WordPress CMS) and download the generated file directly as robots.txt. All processing occurs 100% in secure client-side JavaScript—ensuring your server structure and crawl rules are never transmitted to external servers.

How It Works

Generate a robots.txt file in three steps

Step 1
🤖
Select User-Agent & Paths

Choose targeted crawlers and list path directories to allow or block from indexing.

Step 2
⚙️
Add Sitemap & AI Guard

Include your XML sitemap URL and optionally enable the AI Scraper Bot Guard toggle.

Step 3
📋
Copy or Download File

Copy compiled directives or download robots.txt directly to your server root.

100% Private Local Generation

All directive formatting, sitemap pathing, and file downloads execute locally in your browser. Server structures are never transmitted.

FAQ

Frequently asked questions

What is a robots.txt file and why does every website need one?
A robots.txt file sits in your web root directory (/robots.txt) to instruct web crawlers (like Googlebot) which pages or folders can or cannot be indexed and crawled.
How does the Robots Txt Generator process inputs locally inside browser memory?
'User-agent: *' applies rules universally to all search crawlers. You can also specify targeted rules for specific bots like 'User-agent: Googlebot' or 'User-agent: GPTBot'.
What is the difference between Allow and Disallow directives?
'Disallow: /admin/' instructs bots not to crawl the /admin/ folder. 'Allow: /admin/public.php' explicitly permits access to a specific sub-resource within a disallowed folder.
Can I block AI crawlers (like GPTBot or ClaudeBot) using robots.txt?
Yes. Code parsing, minification, and syntax formatting for the Robots Txt Generator run entirely inside your local browser engine. No source code or markup is transmitted to remote servers.
Where should I upload the generated robots.txt file on my web server?
Upload the generated file directly to the top-level root folder of your web server domain so it is accessible at https://yourdomain.com/robots.txt.
Detailed Guide

Understanding RFC 9309 Robots Exclusion Protocol, User-Agent Tokens & AI Scraper Protection

The Robots Exclusion Protocol (RFC 9309) defines standardized directives (User-agent, Allow, Disallow, Crawl-delay, Sitemap) governing automated search engine web crawler indexing behavior.

Deploying explicit User-Agent rules for AI training scrapers (GPTBot, ChatGPT-User, CCBot, ClaudeBot, PerplexityBot) prevents unauthorized content ingestion and AI model training on proprietary site content.

Placing the compiled robots.txt file in your web domain's root directory (https://yourdomain.com/robots.txt) ensures immediate discovery and compliance by major search engine bots.
