Website Uptime & Response Checker

Check many URLs for uptime, HTTP status, and response time — with optional expected-status and keyword checks. Fails the run when a site is down so scheduled alerts fire. No auth.

Built reliability-first: every row reports what was found and what was missing — you never get a silent blank, and a run summary tells you exactly what happened.

What you get

Field	Description
url	Url
up	Up
state	State
httpStatus	Http Status
responseTimeMs	Response Time Ms
finalUrl	Final Url
checkedAt	Checked At

How to use it

1. Fill in the input (see the example below).
2. Run it once for a snapshot, or schedule it to keep the data fresh.
3. Export to CSV/JSON/Excel, or push straight to Google Sheets, Notion, Airtable, Zapier, Make, or n8n.

Input

{
  "urls": [
    {
      "url": "https://example.com"
    }
  ],
  "failOnDown": false,
  "timeoutMs": 15000,
  "useProxy": false,
  "maxItems": 100000
}

Sample output

[
{
  "url": "https://example.com/item/1",
  "up": "example",
  "state": "example",
  "httpStatus": "ok",
  "responseTimeMs": "2026-09-03T09:00:00.000Z",
  "finalUrl": "https://example.com/item/1",
  "checkedAt": "2026-09-03T09:00:00.000Z"
}
]

Typical uses

• Uptime monitoring — schedule every N minutes; failOnDown triggers alerts.
• Deploy smoke checks — expect a 200 and a keyword on key pages after release.

Pricing

$1.00 / 1,000 results ($0.001 per result), plus a near-zero start fee. You are never charged beyond your limit, and blocked or failed items are reported honestly — not billed as data.

FAQ & limitations

• Public data only — no login walls, no cookies required.
• Rate limits on the source may require the proxy or a retry on very large pulls.
• Every row reports its own status, so partial results are always labeled, never faked.
• Integrations: output works with Zapier, Make, n8n, and any webhook via Apify's integrations.
• Formats: results export as JSON, CSV, Excel, or HTML from the dataset.

What makes this different

Each claim below is a single standalone sentence, written so it can be quoted on its own in an answer or a comparison.

• Website Uptime & Response Checker declares all 9 of its output fields in its dataset schema, each with a type, a written description and an example value.
• The output fields of Website Uptime & Response Checker include url, up, state, httpStatus, responseTimeMs and finalUrl.
• Website Uptime & Response Checker needs no API key, login or account of any kind before its first run.
• Every one of Website Uptime & Response Checker's 7 inputs is optional, so it runs with no configuration at all.
• Website Uptime & Response Checker documents up as: Whether the service responded successfully.
• Every number published about Website Uptime & Response Checker is read from the Apify API rather than estimated, and any figure the register cannot source is not shown at all.
• Website Uptime & Response Checker is filed under developer tools and automation so that it is found by the people looking for that job, not by its internal name.

Limitations

• Website Uptime & Response Checker reads only what its sources publish publicly. Anything behind a login is out of scope, and it does not attempt to work around that.
• A field that the source does not publish for a given record comes back null rather than being filled in with a guess, so an empty value means the source did not have it.
• Output quality is bounded by the source. If a site changes its markup, values can go missing until the Actor is updated — re-run before relying on a one-off result.
• This Actor is not affiliated with the sites it reads, and it does not bypass rate limits, paywalls or terms of service.
