PageSpeed Insights vs 436.io

Everything PageSpeed Insights leaves you to do by hand, free on 436.io

PageSpeed Insights is the engine behind every score here. 436.io is what turns one page at a time into a full site audit, all included on the free plan.

A whole site, not one URL at a time

  • PageSpeed Insights checks a single page per run
  • 436.io finds every page from your sitemap automatically
  • Or scans a sitemap.xml you upload directly
  • Mobile, desktop or both in the same scan

One ranked report, not a page-by-page dump

  • PageSpeed Insights gives a fresh, disconnected report per page
  • 436.io groups recurring issues across every page into one list
  • Ranked by impact and effort, so you know what to fix first
  • Computed from real Lighthouse data, never AI guesswork

Progress you can track, not just a snapshot

  • PageSpeed Insights forgets your last result the moment you leave
  • 436.io saves every scan to your account automatically
  • Compares each new scan against the last one for that site
  • Health score and trend charts across every site you track

Nothing to configure, nothing to pay

  • PageSpeed Insights needs your own API key for real usage
  • 436.io runs on a shared key, no setup on your side
  • Full prioritized reports and scan history included
  • Free to use, no trial and no time limit

Every category, every time

  • Performance, Accessibility, Best Practices and SEO together
  • No switching between separate PageSpeed Insights tabs
  • Mobile and desktop compared side by side
  • Every strategy and category combination covered automatically

Findings tied to your actual goals

  • Tell 436.io your site type and goals up front
  • Strategy Analysis ties findings to what matters to you
  • Clear recommendations, not just raw audit names
  • The same scan always produces the same report

A dashboard across your whole portfolio

  • One health score across every site you track
  • Category breakdown for each site at a glance
  • Trend charts spanning weeks or months
  • Filter by site or see everything together

A report you can actually share

  • One clean PDF, not a page you'd have to screenshot
  • Covers the overview, actionable report, per-page detail and strategy
  • Built for handing to a client or a teammate
  • Free to download on every scan
