Domain monitoring for SaaS founders
Your product domain is the obvious one to monitor. The blog subdomain, the legacy redirect from your previous name, the auth-callback hostname, the status page, the docs subdomain — those are where SSL silently expires and conversion quietly drops. ManageCert watches every domain you own, not just the one you remember.
Your product is at app.yourdomain.com. Your marketing is at yourdomain.com. Your auth callback is at auth.yourdomain.com. Your status page is at status.yourdomain.com. Your old marketing site (now a redirect) is at the previous brand's domain. One of those has a cert that quietly fails to renew. You don't notice until users start asking why one specific link is showing a browser warning. ManageCert is the daily check that covers every hostname.
Why ManageCert for SaaS founders
Every subdomain + every legacy domain
Add every hostname you serve, including legacy redirects from a rebrand. Each tracked independently — failure on one stops hiding behind a working apex.
Catches the customer-domain CNAME case
If your product supports vanity domains via CNAME (think Webflow, Beehiiv, or any multi-tenant SaaS), every customer domain is its own SSL renewal. We watch them too.
