FAQ
What is robots.txt?
robots.txt is a text file at the root of your site (e.g. example.com/robots.txt) that tells search engine crawlers which parts of your site they may or may not crawl. It uses the Robots Exclusion Protocol.
What's the difference between Disallow and noindex?
Disallow tells crawlers not to crawl a URL — but if a URL is linked from elsewhere, it may still appear in search results without a description. To prevent indexing entirely, use the robots meta tag with noindex instead.
What are wildcard patterns?
The * wildcard matches any sequence of characters and $ marks the end of a URL. For example, Disallow: /*? blocks all URLs with a query string, and Disallow: /*.pdf$ blocks all PDF files.
What extra features does this tool have compared to others?
(1) User-agent presets — Googlebot, Bingbot, Slurp, DuckDuckBot, Baiduspider, YandexBot, facebookexternalhit, AhrefsBot, SemrushBot, GPTBot. (2) Allow/disallow toggle per rule. (3) Path pattern builder with wildcard support. (4) Sitemap auto-include. (5) Crawl-delay directive. (6) Comments. (7) Live preview. (8) Validation warnings (e.g., path without leading slash). (9) Stats — rule count per user-agent. (10) History (localStorage, last 20).
Is my data sent anywhere?
No. robots.txt generation is pure string templating in your browser. History is stored in localStorage on this device only.
