Crawler information

How our scanner identifies itself, the limits it respects, and how to control it.

Last updated: 18 October 2026

About our crawler

When UrlTestly inspects a website, it identifies itself with a clear user agent so site owners can recognize the traffic:

  • User agent: Mozilla/5.0 (compatible; UrlTestlyBot/1.0; +https://urltestly.com/crawler)
  • Purpose: On-demand safety and reputation analysis requested by a visitor.
  • Behavior: A single, lightweight visit per scan. We do not perform large-scale crawling of your site.

Request limits

Every scan operates within strict limits to be a good citizen of the web:

  • A short connection and overall request timeout
  • A capped number of redirects followed
  • A capped amount of HTML downloaded per page
  • robots.txt and sitemap reads are size-limited
  • Free scans are rate-limited per visitor

Respecting robots.txt

Because a scan is an explicit, user-initiated safety check of a single page, it behaves like a visitor rather than an indexing crawler. We read robots.txt and sitemap declarations, and we never bulk-crawl a site.

Preventing scans of your site

If you operate a site and prefer not to be scanned, you can block our user agent at your edge or CDN. If you believe our crawler is behaving incorrectly, contact [email protected] and we'll investigate promptly.
