Page Canary

Page Canary is an AI QA agent for websites. It tests your site the way a customer would and tells you when something breaks. Unlike uptime monitors, which only check whether a URL responds, Page Canary loads pages in a real browser and reports what is actually broken for visitors. It works on any public website.

How it works

You paste in a URL, and Page Canary finds your pages and your critical flow on its own, such as booking, a contact form, checkout or signup, without setup or code. Every week it walks that flow in a real browser, stopping before anything is booked or bought. Every day it loads up to 15 key pages on desktop and mobile. You see a recording of every walk. When a problem appears on two checks, you get an email explaining what is wrong and how to fix it, and a note when it is resolved.

What it checks

Critical flows: booking reaches the calendar, checkout reaches the payment page, signup reaches the account form, and contact forms send and the message arrives. It never books, buys or creates an account, and contact forms only send once you say so. Broken pages and links: it checks key pages and every internal link on them, and re-checks anything broken in a real browser before reporting it. Errors on the page: it spots errors visitors actually see, including JavaScript errors that only appear in production. Mobile problems: it loads key pages on a phone-sized screen and checks that the menu works and nothing overflows. Site-wide checks cover SSL and domain expiry and search problems that could hide a site.

For agencies

Agencies can monitor every client site and send monthly reports that clients understand, built from the weekly walks and daily checks.

Trying it

You can watch it test your site for free, with no signup, in about a minute. Check the site for plan prices.

Things to consider

Page Canary only covers public pages and the flows it detects, so it complements rather than replaces your own testing of logged-in areas and payments. Requiring two failed checks reduces false alarms but means a brief delay before alerts.
