The IsDown alternative
ServiceAlert.ai covers what IsDown does, plus everything else in your operational stack, for $249/month flat.

Where ServiceAlert.ai wins
When to pick IsDown instead
If you only need third-party status aggregation for a small team and Chrome-extension visibility matters most, IsDown is a focused product. ServiceAlert is the broader reliability workflow for vendor status, first-party uptime, status pages, incidents, and certificate lifecycle.
The bundle math
ServiceAlert.ai is designed as a platform: the $249/mo Business plan gives you uptime monitoring, third-party vendor status aggregation, certificate lifecycle, status pages, and incident management in one login. To reach that capability footprint with IsDown, you'd need to stack it with three to four other products. See the methodology page for the cited numbers we use in our stack-replacement comparison.
