Hey Product Hunt! 👋 I'm Saurabh, founder of Alert91. This started because I was managing client websites for a web agency and kept getting the same call: "the site's down" or "something looks off" — hours after it actually happened. Generic uptime tools told me a server was reachable, but they had no idea if the page was defaced, if an SSL cert was about to expire, or if the site had quietly dropped out of AI search results. So I built Alert91 to be the monitoring layer an agency actually needs — uptime, security, SSL/domain expiry, defacement detection, and SEO/AEO/accessibility audits, all in one dashboard across every client site. The part I'm most excited about is our AI Visibility Check. Instead of guessing how "AI-friendly" a site is, it actually asks ChatGPT, Claude, Gemini, and Perplexity real questions about your brand and reports whether each one mentions you — because with AI answer engines increasingly replacing search clicks, "are you even in the room" matters as much as your Google ranking. Would love your feedback — what would make this genuinely useful for how you or your agency monitors client sites? Happy to answer anything below

Honestly the AI visibility check sounds super useful, but I'd love to see a Slack or Teams alert when one of those models suddenly stops mentioning a brand. Right now it's more of a scheduled report, kind of reactive. A real time ping when your mention drops would make it way more actionable for agencies handling multiple clients.
