Choosing well
Which DNS checks does it need to run?
Choose a product that covers the checks you need, such as resolution, propagation, record changes, or nameserver health.
Compare check intervals and query locations too; these are distinct criteria in the directory.
How should it alert me?
Choose a product with alert channels that fit how you want to receive DNS updates.
Check whether record-change alerts and nameserver health checks are included in the product's coverage.
Which platforms does it need to run on?
Check the product's listed platforms before choosing, including whether it has an Android app if you want to monitor from a phone.
Web, API, Linux, self-hosted, Windows, and Android are platform options represented in this category; do not assume one listing supports them all.
Can I use a free plan or trial?
Compare the free plan, paid starting price, and trial terms before you commit.
A free plan and a free trial are separate options, so check which one a product offers and what its pricing details say.
