>Domain only

OK, there's another option for deploying to a server and allowing domain users to hit the PBI pages with a browser.

Microsoft offers Power BI Report Server (On-Premise)

If you are at all familiar with SQL Reporting Services, where you can deploy SSRS reports to an internal server and allow users to hit it with a browser (and without needing IIS)....Power BI Report Server works the same way. You can deploy your PBIX reports to an internal PBI report server, and users can access the reports in the same way they'd access SSRS reports.

So you can create your own basic menu system to organize your reports/report folders/etc

There's only one catch - it's "how to buy" Power BI Report Server, and Microsoft has made it strange.

If you have SQL Server Enterprise + Software Assurance, you can get Power BI report Server for free.

If you don't own those, you have to get Power BI Premium....which is not cheap. (I have heard different street prices available through Microsoft partners/vendors, but I know it's at least a few thousand a month)

So clearly, Microsoft's unspoken message here is pretty clear: yes, they offer an on-premise report server option for Power BI reports that does not involve IIS or the cloud - but one way or another, it's quite pricey, and they want people to move towards the cloud.

So - yes, Power BI desktop is free. But if you want to have shared pages and shared reports and access to this type of output in a browser, it's no longer free.

My company uses both Power BI Report Server (for internal reports), but we also have some PBI visualizations on our customer portal that outside users can see. For that second one, we deploy the reports to the cloud (where we have a Power BI Premium license), and then we use the iFrame trick (and another .NET component called Power BI embedded) to make our PBI content available inside of our own .NET web portal pages.
