Which Version to Install

SN Utils comes in two versions, each with a distinct icon so you can tell them apart at a glance:

VersionIconUse when
SN Utils regular iconSN Utils (regular)GreenAll your instances are on *.service-now.com
SN Utils OnPrem iconSN Utils OnPremBlueAny instance uses a custom or local domain (e.g. sn.acme.com)

The codebase for both versions is identical — you won't miss any features regardless of which one you choose. The only difference is in the host permissions: the regular version is locked to *.service-now.com, while OnPrem requests access to all URLs so it can run on any domain.

Troubleshooting

If you see the message "SN Utils does not run on the current page!", you are likely using the standard extension on a non service-now.com domain. See:
