Uptime Monitoring
Uptime Monitoring for SaaS Products
HTTP 200 doesn't mean your product is working. Here's what SaaS teams actually need to monitor.
The problem with ping-based uptime monitoring
Most uptime monitoring tools work by sending a GET request to your URL and checking if it returns 200. If it does, the monitor shows green. But a SaaS product can return 200 from a CDN cache while the application server is completely down, the login form is broken, or the checkout flow returns an error page with a 200 status.
Customers experience the failure. Your uptime tool shows everything is fine. This is the gap that content-level monitoring closes.
What to actually monitor on a SaaS product
Login page CTA
Monitor the submit button text or form action attribute. If it disappears or changes, the login flow may be broken.
Signup conversion element
Watch the primary CTA on your signup page. Broken JS, a failed A/B test, or a CDN rollback can remove it silently.
Pricing page plan names
Ensure your pricing table renders correctly after deployments. A missing plan or broken price element loses you signups.
Status page last-updated time
If your status page stops updating, customers assume the worst. Monitor the timestamp to confirm it's receiving updates.
Layering availability and content checks
The best approach for SaaS monitoring is layered: use traditional uptime monitoring for raw availability and add selector-based content monitoring for functional correctness. WatchPage provides the content layer — you point it at critical UI elements and it alerts you when they change or disappear.
Alert routing for on-call teams
Content-change alerts are most useful when they route to the person who can act on them. Pricing page changes should go to the growth team. Login page changes should go to engineering. Telegram and email channels in WatchPage let you configure separate alert destinations per monitor so notifications reach the right owner.
