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.

// the pain

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.

Solo tier $19/mo to start

10 domains for $19/mo is the right shape for a small SaaS. Scale to Pro ($39, 50 domains) as you grow.
