Official pricing and specifications checked September 8, 2026. This is not a benchmark of competitors’ capture speed or success rates. Kiroku operates this website.

Quick Take
  • Compare the monthly check allowance as well as the shortest interval.
  • Distinguish local checks on your device from cloud monitoring.
  • For terms and pricing, inspect both saved versions and the diff.
  • Kiroku checks about every six hours, so it is not suited to minute-by-minute stock or booking alerts.

Choose a monitoring tool by how quickly you need an alert, how many pages you watch, and whether you need the earlier wording afterward. A free alert allowance may be enough; terms and pricing reviews also need useful saved versions and clear capture limits.

If you keep reopening a pricing or terms page to look for edits, compare website update alerts and content change detection tools. An uptime service answers a different question: whether the site is reachable.

Start with what you need to do after an alert. Knowing that a page changed may be enough. If you need to read its previous wording, compare the saved versions, history limits and export options as well.

Decide what you need after the alert

Direct Answer

An update alert and a readable record of the earlier page solve different parts of the job.

Compare starting prices and operating conditions

Direct Answer

This comparison uses official product information, not a head-to-head reliability benchmark. Check current prices and allowances on the provider’s site before purchasing.

A free plan may be enough

If you only need an update alert for a few pages, try a free monitoring allowance. Kiroku’s free Guest service is for individual public saves; ongoing monitoring requires Pro.

Kiroku Pro

Keep the previous wording when a page changes

Pro checks public URLs about every six hours. Review saved versions and text differences, and keep your archive records private when needed.

  • Inspect the first saved version after setup
  • Review detected changes and any capture errors
  • Private archives, saved versions and evidence-pack exports

A short interval does not mean unlimited checks

Direct Answer

Ten pages checked every six hours for 30 days require 10 × 4 × 30 = 1,200 checks. A service may let you select a short interval without including enough monthly checks to run every page at that interval.

For local monitoring, check whether your device must stay on. Cloud monitoring can keep running independently, but login screens and access restrictions can produce a different result from the page you see yourself.

Inspect the versions a change leaves behind

Direct Answer

In a controlled Kiroku example, we changed a fictional price from $40 to $55 and its saved-page allowance from 100 to 50. We captured HTML and screenshots in a browser. The existing comparison code identified the two edited lines as one changed block.

A second example changes a cancellation deadline from 30 to 45 days before renewal. It produces a one-line difference. Comparing an unchanged version with itself did not qualify for an alert.

These are local capture and comparison results. They do not test production scheduling, email delivery or external timestamping. The saved HTML, screenshots, email text preview and test results are available to inspect.

Start with one representative URL

4 Easy Steps
1
Choose a public page

Check support first if the page needs a login or special access.

2
Inspect the initial capture

Confirm that the wording and prices are present. Registering a URL does not prove that the content was captured.

3
Review a diff and any errors

Compare the saved versions. A failed request alone is not proof that a publisher deleted a page.

4
Check the ongoing cost

Account for page count, history, alerts, storage and what happens when you cancel.

Summary

Choose a monitoring tool by how quickly you need an alert, how many pages you watch, and whether you need the earlier wording afterward. A free alert allowance may be enough; terms and pricing reviews also need useful saved versions and clear capture limits.

FAQ

Can I get website update alerts for free?

Some services offer free monitoring allowances. Compare check counts, alert limits and history as well as page counts. Kiroku’s ongoing monitoring is included in its paid Pro plan.

Does Kiroku send instant alerts?

No. URL checks run about every six hours. A change that appears and disappears between checks can be missed.

Can monitoring recover a page that was already deleted?

Monitoring preserves versions captured from now on. It cannot recover content removed before the first save; searching existing archives is a separate task.
