Response Time Analyzer

See exactly where a page spends its time — DNS, TCP, TLS, time-to-first-byte, total transfer, and payload size — for any URL.

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

What you get

For each URL, a full timing breakdown measured directly off the socket lifecycle (no headless browser overhead):

dnsMs — DNS lookup time
connectMs — TCP connect time
tlsMs — TLS handshake time (0 for plain HTTP)
ttfbMs — time to first byte (request sent → response headers in)
totalMs — full transfer time, headers + body
bytes / sizeKb — actual payload size transferred
status — HTTP status code

Pass samples > 1 to average each timing across multiple requests and smooth out jitter. Send one url or a bulk urls list — bare hostnames default to https://.

Input

{
  "url": "https://github.com",
  "urls": ["https://wikipedia.org", "https://example.com"],
  "maxUrls": 25,
  "samples": 3
}

Output

{
  "url": "https://github.com/",
  "status": 200,
  "samples": 3,
  "timing": {
    "dnsMs": 12.4,
    "connectMs": 18.7,
    "tlsMs": 34.1,
    "ttfbMs": 210.5,
    "totalMs": 412.9
  },
  "bytes": 284512,
  "sizeKb": 277.84
}

Spot slow pages, regressions, and bloated payloads — one URL or a whole list at a time.
