Robots.txt Generator & AI Scraper Blocker

The problem: Configuring robots.txt syntax errors or forgetting to block aggressive AI crawlers can leak internal URLs or exhaust server resources.

Robots.txt Generator & AI Scraper Blocker: the complete guide

A Robots.txt Generator and Syntax Validator creates search-engine-compliant crawler instructions to direct Googlebot, Bingbot, and AI spiders on which website directories to index or ignore. Proper robots.txt configuration protects sensitive administrative dashboards, internal search result pages, and private APIs from accidental public search engine exposure while ensuring public content is discovered. This tool includes 1-click blocking for modern AI scrapers and automated syntax validation.

The Robots Exclusion Protocol (RFC 9309) Explained

Standardized under RFC 9309, the Robots Exclusion Protocol instructs automated web crawlers through directive records grouped by User-agent headers. The Disallow directive instructs compliant spiders not to crawl specific URL paths, while the Allow directive explicitly permits access to subdirectories within disallowed paths. A trailing slash indicates directory matching (e.g. /admin/ protects all nested URLs).

Managing Modern AI Scrapers & Data Harvesters

With the rise of large language models, webmasters increasingly manage AI training bots (such as OpenAI's GPTBot, Common Crawl's CCBot, Anthropic's ClaudeBot, and ByteDance's Bytespider) separately from commercial search crawlers. Declaring explicit Disallow rules for AI agents prevents unauthorized content harvesting while maintaining search visibility on Google and Bing.

Step by step: how to use Robots.txt Maker

  1. 1

    Choose a starting preset (Standard Production or Disallow All for staging environments).

  2. 2

    Optionally click 'Block AI Crawlers' to automatically insert rules for 8 major LLM bots.

  3. 3

    Input disallowed URL paths (such as /admin/, /api/, /cart/) one per line.

  4. 4

    Enter your absolute XML sitemap URL (e.g., https://example.com/sitemap.xml).

  5. 5

    Review the generated robots.txt preview and inspect syntax recommendations.

  6. 6

    Click 'Download' to save the file or 'Copy' to paste into your public web root.

Security & privacy

Zero telemetry. All robots.txt configurations and domain URLs remain 100% inside your browser tab without recording domain names or internal paths.
