Assertible is an alternative to Pingdom





Deep API and website validation by default

Check for more than just UP or DOWN


Downtime alerts and notifications are critical. Assertible provides actionable and fine-grained alerts out of the box so your team can immediately understand the nature of degraded services.



We want to make system maintenance and downtime response as simple as possible by providing specific alerts with key information about your web service, endpoint, and failure.

Pingdom's default notifications, on the other hand, lack critical information needed to understand downtime immediately and almost always require a second step to understand why a check is failing.

First-class API support


Assertible is built around the concept of real-world web services, and allows you to reuse the same tests against multiple url endpoints or region-specific instances of your web service.

Assertible also makes it possible to monitor a web service in customizable intervals as well as execute tests after deployments

Services like Pingdom provide a loose test structure that lacks context and can result in flaky tests which are difficult to debug.
