Could you build this?

Partial The dashboard, alerting, and incident reports are standard CRUD-style work, but reliable browser-based checks (JS errors, browser failures) from multiple regions require real headless-browser infrastructure that is costly to run and keep stable.

What it would actually take: Build a scheduler and worker fleet running headless Chromium (Playwright or Puppeteer) in several geographic regions, with DNS, SSL, and HTTP checks alongside. Store time-series results and render incident reports with captured screenshots, HAR files, and console logs. The hard part is operating that browser fleet at scale with low false-positive rates, which needs DevOps and monitoring-systems experience.
