Browser Monitoring vs Uptime Monitoring
A page can return 200 while login, forms, JavaScript, or checkout are broken. Here is when a real browser check earns its place.

Field notes on reliability
Reliable digital experiences are built from small signals. A page can return a successful response and still leave a customer staring at a broken button. A certificate can be valid today and become an incident tomorrow.
A successful response can still be broken
An uptime check can confirm that a server responded with 200. It cannot confirm that JavaScript rendered the checkout, that a login redirect completed, or that a customer could click the purchase button.
What a browser check adds
A real Chromium session can navigate, click, fill fields, wait for UI state, assert text or URLs, and capture screenshots. It tests the customer journey rather than only the server response.
Keep the check focused
Choose one or two revenue-critical journeys first. A login flow, lead form, product selection, or checkout handoff usually provides more value than trying to automate every path on the site.
Use the evidence when it fails
The failing step identifies where the journey stopped. A screenshot shows what the user saw, while the HAR trace helps separate an application bug from a failed third-party request or network dependency.
Keep watch, keep the signal clear, and give your team room to move with confidence.
