    The AI angle

    Lighthouse vs AI

    AI augments this tool
    Go further with AI

    Lighthouse (Google) already uses models to score a page's performance, accessibility, and SEO, but remains an objective technical measurement tool based on real loading data.

    Can AI replace it?

    Replace Lighthouse with an AI? No: objectively measuring a page's real load time and accessibility requires real performance data, not generation. Verdict: AI helps interpret the report, it can't invent the measurement itself.
