Build and validate robots.txt files with a visual builder or text editor. Configure user-agent rules, allow/disallow paths, crawl-delay, and sitemap URLs. Includes 6 presets (Allow All, Block All, Block AI Crawlers, Blog, E-commerce, WordPress) and 17 known bot user-agents. Runs entirely in your browser — your data never leaves your machine.

All interactive tools run entirely in your browser. Your data never leaves your device.

How It Works

Switch between Builder mode (visual form) and Editor mode (raw text). In Builder mode, add user-agent rules with allow/disallow paths, crawl-delay, and sitemap URL. In Editor mode, paste or edit robots.txt directly with live validation. Both modes show the generated output ready to copy.

Features

  • 2 modes: visual builder and raw text editor
  • 6 presets: Allow All, Block All, Block AI Crawlers, Standard Blog, E-commerce, WordPress
  • 17 known bots: Googlebot, Bingbot, GPTBot, anthropic-ai, and more
  • Rule management: add/remove rules, allow/disallow paths, crawl-delay
  • Sitemap URL: add sitemap directive
  • Validation: parse errors and warnings (missing paths, non-absolute sitemap URLs)
  • Copy to clipboard: one-click copy of generated output
  • Private: runs entirely in the browser — no data transmitted

Use Cases

  • Generating robots.txt for new websites
  • Blocking AI crawlers from scraping your content
  • Setting up crawl rules for e-commerce sites
  • Validating existing robots.txt files for errors
  • Quick-starting with platform-specific presets (WordPress, etc.)
