Client sites silently rot with security holes and functional bugs that nobody monitors, destroying trust and exposing sensitive data

Summary

Site owners and the agencies/devs who maintain their storefronts have no ongoing view of whether a live site is actually secure and functional. In this case a 'vibe-coded' real-estate service website looked polished but was riddled with unauthenticated links carrying unencrypted payloads, broken login flows requiring refreshes, duplicated/miscategorized requests, and files that won't download — all discovered only through a client's painful end-to-end experience. There is no lightweight, cross-platform monitoring layer that continuously checks a site for broken auth, unprotected links, failing downloads, duplicate requests, performance regressions, and exposed sensitive data, then flags them in plain language before a customer hits them. Existing tools each watch a single silo (uptime pings, a security scanner, a lighthouse score) and none cross-check the live storefront end-to-end per client. The pain is severe: failures surface as surprise client complaints, erode trust in 6–7 figure transactions, and expose personal/financial data — yet the small teams running these sites don't have real developers or any system that would have caught it. This gap is unsolved for the multi-client, multi-platform agency case.
