PageLint

¿Qué es PageLint?

PageLint scans any webpage and gives you a quality score across SEO, Accessibility, Performance, and Language. Unlike Lighthouse (30+ seconds), PageLint runs in 3 seconds using native Performance API for real FCP/LCP metrics. What's different: • Every issue has a fix suggestion — tells you how to fix it • Score by dimension so you see what's weakest • Export HTML reports for your team • 16 rules, 8 languages, dark mode • 100% local — no data leaves your browser Free, no account needed.
