How it works

You paste a URL. That is your last job.

KeyPages opens the live page in a real browser, works out what the page is for, turns on the protections that fit it, and keeps checking as you ship.

Step 01 — you

Paste the URL.

https://Protect

No scripts. No selectors. No config file. That is the entire setup.

Step 02 — KeyPages

Everything else, on its own.

What it works out

A path is enough to know what the page owes its visitors.

The URL is not just an address to ping. It tells KeyPages what kind of page this is, and therefore the one job it has to keep doing.

  • /signupSignup pageCreate an account
  • /loginLogin pageSign in
  • /pricingPricing pageReach the primary CTA
  • /searchSearch pageGet useful results
  • /products/widgetProduct pageAdd to cart
  • /checkoutCheckout entryReach checkout

No selectors written. No Playwright script. No monitoring topology to design.

The check itself

Five moves, then it starts over.

This is not a one-time audit. It is a loop that runs against your live app for as long as the page is protected.

  1. 01

    Open the live page

    In a real browser, against production — not a preview build.

  2. 02

    Run what applies

    Only the protections that make sense for this kind of page.

  3. 03

    Capture evidence

    Screenshot, rendered HTML, and browser context.

  4. 04

    Compare to healthy

    Against the last verified good version of this page.

  5. 05

    Update the status

    A real failure becomes an issue you can read.

and again in five minutes
When it breaks

An alert that explains itself.

Most monitoring hands you a status code and leaves the diagnosis to you. An issue in KeyPages is written so that the failure, the impact, and the next move are all in one place.

Everything on the right came out of a single automated check. Nobody wrote it by hand.

Expected
A visitor can create an account.
Observed
The signup form is not present on the page.
Why it matters
Nobody arriving on this page can start an account. The page still returns HTTP 200.
Next step
Check the signup form component in the change you shipped at 09:14.
Screenshot attachedThe page exactly as the check found it
One morning, end to end

Broken at 09:14. Verified fixed by 10:07.

  1. 09:14

    You shipped a change

    A layout edit removed the signup form. Every uptime signal stayed green.

  2. 09:41

    KeyPages caught it

    The key action failed in a real browser. You were alerted with evidence attached.

  3. 10:02

    You pushed a fix

    One component restored. No test suite to update afterwards.

  4. 10:07

    Recovery verified

    A later real-browser check confirmed a visitor can create an account again.

The issue stays in history after it closes, so the next report shows what was protected, what broke, and what recovered.

If you want to go deeper

The raw evidence is kept for every check.

Screenshot capture

What a customer could actually see.

Rendered HTML

The page after JavaScript has run.

Browser context

Console and runtime detail, when that is the answer.

Baselines

The healthy version each check compares against.
