Page Weight Analyzer — page size, resource counts & performance hints

Estimate a page's weight and get actionable performance hints from a single fetch — no headless browser. Returns HTML size, transfer (compressed) size, counts of scripts/styles/images/ fonts, render-blocking resources, and specific fixes. Single URL or bulk. $0.001 per page. Failed fetches are recorded free.

What you get

HTML + transfer size (KB), with detected compression.
Resource counts: external/inline scripts, external/inline styles, images, fonts.
Render-blocking scripts + stylesheets in <head>, and scripts missing async/defer.
Inline JS/CSS weight and an estimated request count.
Hints — concrete, prioritized fixes.
Fail-soft: an unreachable URL returns {ok:false, error} and is never charged.

Input

{ "url": "https://github.com", "urls": ["https://example.com"], "maxUrls": 25 }

Output (real run, 2026-08-07)

{
  "ok": true, "url": "https://github.com/", "status": 200,
  "htmlKb": 559.37, "transferKb": 559.37, "compression": "gzip",
  "counts": { "scripts": 15, "styles": 42, "images": 24, "fonts": 1 },
  "inlineJsKb": 132.57, "renderBlocking": 30, "renderBlockingStyles": 30,
  "estimatedRequests": 76,
  "hints": ["30 render-blocking stylesheet(s) in <head> — inline critical CSS and lazy-load the rest.", "…"]
}

Pricing — $0.001 per page

A lightweight HTML-only analyzer, priced far below the Lighthouse-style actors on the Apify Store (measured 2026-08-07: nexgendata/page-speed-analyzer $0.1/item · miccho27/seo-analyzer $0.03/item · alizarin pagespeed-insights $0.02/url-analysis). Those render the page in a headless browser; this one parses the served HTML, so it is ~20–100× cheaper for a fast weight + hints pass.

Limits (honest ones)

Analyzes the served HTML — it does not download each sub-resource or run JavaScript, so sizes for external JS/CSS/images are counted, not summed. Use a headless Lighthouse actor for fully-rendered metrics.
Transfer size uses the server's Content-Length, or a gzip estimate when absent.
maxUrls capped at 50 per run.

FAQ

Does it run Lighthouse? No — it is a fast HTML-only pass (counts, sizes, render-blocking, hints). That is what makes it cheap.
Does it measure external file sizes? It counts external resources and measures inline JS/CSS; it does not fetch each external file.
What about a dead URL? You get an {ok:false, error} record, uncharged.
