# Web-PSQC

> Web-PSQC (www.web-psqc.com) is a free website testing service by DevTeam Co., Ltd. Enter a URL and it runs 18 tests — load speed from 8 global regions, Lighthouse Core Web Vitals, mobile, SSL/TLS, security headers, accessibility (WCAG), browser compatibility, SEO, structured data, crawlability and AI-search visibility (GEO) — and shows each result live as it finishes. Sites scoring B or better can get a verifiable certificate.

Results are scored 0–100 per test and graded A+ (95+), A (90+), B (80+), C (70+), D (60+) or F. Load testing, OWASP ZAP and Nuclei scans run only on verified domains.
