WebPSQCBot

Web-PSQC tests websites only when a person asks for it by entering a URL. We do not crawl the web on our own.

User agents

• Mozilla/5.0 (compatible; WebPSQCBot/3.0; +https://www.web-psqc.com/bot) — HTML, robots.txt, sitemap and link checks.
• Regular Chrome, Firefox and Safari (WebKit) user agents — browser-based tests (Lighthouse, mobile, accessibility, compatibility).
• The AI crawler access test briefly sends one request each with the public user agents of OAI-SearchBot, GPTBot, ClaudeBot and PerplexityBot to see whether your firewall treats them differently. These requests come from our server, not from those companies.

Where requests come from

Our test server runs on AWS in Virginia, USA. The global speed test uses probes in 8 AWS regions (Seoul, Tokyo, Singapore, Sydney, Frankfurt, London, Virginia and Oregon).

Volume

A full test makes a few dozen requests in total; the link check fetches up to 20 pages. Load tests (k6) and vulnerability scans (ZAP, Nuclei) only run on domains whose owner has verified them.
