Page Weight & Performance Hints

Know how heavy a web page really is — and exactly what to fix — in one fast HTTP fetch. No headless browser, no waiting.

Live on the Apify Store — run it instantly or call it as an agent tool via Apify MCP.

What you get

For each URL the actor returns:

HTML size (htmlKb) and estimated transfer size over the wire (transferKb, gzip-aware).
Resource counts — scripts (external + inline), stylesheets, images, fonts.
Render-blocking resources — head scripts without async/defer and blocking stylesheets.
Inline weight — total inline JS and CSS in KB.
Compression check — flags pages served without gzip/brotli.
Rough request count — quick estimate of total round-trips.
Actionable hints — prioritized quick wins (lazy-load images, defer scripts, enable compression, minify HTML, and more).

Single URL or bulk list. Each page is analyzed independently — one bad URL never fails the run.

Input

{
  "url": "https://github.com",
  "maxUrls": 25
}

Or analyze many at once:

{
  "urls": ["https://github.com", "https://wikipedia.org"],
  "maxUrls": 50
}

Output

{
  "url": "https://github.com",
  "status": 200,
  "htmlKb": 285.4,
  "transferKb": 41.2,
  "compression": "gzip",
  "counts": {
    "scripts": 12,
    "styles": 3,
    "images": 7,
    "fonts": 2
  },
  "inlineJsKb": 3.1,
  "inlineCssKb": 0.8,
  "renderBlocking": 2,
  "estimatedRequests": 24,
  "hints": [
    "2 render-blocking script(s) in <head> — add async/defer or move to end of <body>.",
    "HTML document is large (285.4KB) — minify markup and reduce server-rendered bloat."
  ]
}

Use it for SEO audits, performance monitoring, competitor benchmarking, or as a tool in your AI agent pipeline.
