Agency Infrastructure
Standard monitors check if a site is alive. Spectre checks if it is healthy, compliant, and converting. The headless watchdog for agencies managing 50+ assets.
Active Nodes Deployed At
You manage 50+ client websites. UptimeRobot says they are all "Up".
But Client A's contact form is broken (SMTP error).
Client B's SSL certificate expired yesterday.
Client C's Privacy Policy is dated 2019.
You don't know until the client calls you. Your reputation takes the hit.
Spectre spawns a Puppeteer instance to render your site like a real user. It detects JS crashes, layout shifts, and hydration failures.
Never let a certificate expire again. Spectre alerts you 30, 14, and 3 days before expiration. It also scans for Mixed Content warnings.
Deep scan for identifying tech stacks (Next.js, WordPress), missing SEO tags, and checking if Analytics/GTM tags are firing correctly.

"We manage 120 sites. Spectre found a broken contact form on our biggest client's site before they noticed. Saved us a $50k retainer."
"UptimeRobot tells me if the server is on fire. Spectre tells me if the website actually works. It's a non-negotiable part of our stack now."
"The automated SSL warnings are a lifesaver. The white-label reporting makes us look like geniuses to our clients."
UptimeRobot simply "pings" a server. Spectre launches a headless Chrome browser to actually render your site, checking for JavaScript errors, broken forms, and visual layout shifts.
Zero impact. Our crawlers operate from external data centers and simulate a single user visit per scan interval. We do not install any code on your website.
