What is the Bigfix Inventory Web Based on?
We want to know Bigfix Inventory Web Based on what application like IIS or Apache.
Could anyone help to answer the question or document for it?

BFI uses WebSphere Liberty.

Thanks for your help~
And if there is any document mentioned it?

I dont see any specific mentions where it says something like BigFix Inventory is based on WebSphere Liberty but the release notes for BigFix Inventory often mention version upgrades for websphere liberty:

WebSphere Application Server Liberty is upgraded to version


The latest version is IBM WebSphere Liberty version‚Äč
