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.

Why BunchTool

🤖
Targeted Search Crawler Control

Build specific index rules for search bots (Googlebot, Bingbot) and control crawler access across private directories.

🛡️
AI Scraper Bot Guard

Prevent automated AI crawlers (GPTBot, ClaudeBot, CCBot) from scraping your proprietary web content for AI training.

🔒
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.
