Generate, Validate, and browse Robots.txt templates
The Robots.txt Generator & Validator Toolkit is the ultimate command center for managing search engine crawler access. The robots.txt file is the first protocol that Googlebot, Bingbot, and AI scrapers check before crawling your website. A single syntax error in this file can accidentally de-index your entire domain from Google Search. This offline utility empowers SEO specialists to safely generate standard crawler directives, construct explicit Allow/Disallow path rules, and define XML Sitemap locations. The real-time validator engine locally parses your existing robots.txt files to identify critical syntax errors, missing wildcards, or conflicting directives. Protect your crawl budget and securely block unauthorized AI data scrapers using our library of pre-configured templates.
WebToolkit Pro is engineered for zero-trust environments. This utility processes your sensitive data entirely within your browser using Web Workers.
Validates syntax by splitting string entries and evaluating regex conditions locally against standard directives.

# Block known AI scrapers from consuming data

Disallow: /
Sitemap: https://yourdomain.com/sitemap.xmlIf search engines cannot parse your robots.txt due to malformed syntax, they may assume there are no restrictions and crawl private areas of your site, or alternatively, halt crawling entirely out of caution.
You can use the generator's AI-blocking template, which automatically outputs disallow directives for known AI crawlers like GPTBot, CCBot, and ClaudeBot, preventing them from using your content for LLM training.
The file must be named 'robots.txt' and uploaded to the absolute root directory of your website domain (e.g., https://yourwebsite.com/robots.txt).
