For 6 years I heard the same story from clients: "My site was broken for hours but my monitoring tool said everything was fine." A plugin update breaks the checkout page, a theme conflict wipes the hero section, a CDE glitch swaps out images — but the server still returns 200 OK, so nobody gets alerted. That's why I built Visual Sentinel. It doesn't just ping your server — it takes screenshots, compares them pixel-by-pixel, and alerts you the moment something looks wrong. Uptime is just one of 6 layers we monitor (Performance, SSL, DNS, Visual Changes, and Content Integrity). No code to install, no agents, no browser extensions. Paste your URL and you're protected in 60 seconds. Alerts go wherever your team already works — Slack, Discord, WhatsApp, Telegram, Email, or webhooks. I built this for the small business owner who can't afford to lose customers overnight, and the agency owner managing 50+ client sites who needs to know before their clients do. Would love to hear what you think — and if you've ever been burned by a "200 OK but completely broken" situation, I'd love to hear that story too.
