What is a premium license and do I need one?

A premium license is needed to use SPX GC in a commercial use. With the purchase of SPX GC for Professionals, it comes with a premium license which covers up to 10 machines to install the software to. If you need more seats, either purchase another license or contact us as an enterprise customer for a bespoke solution.

Where do i get HTML-graphics anyways? 

HTML-based live graphics is becoming more and more popular in the industry. As it is the point of an open-source software, anyone can make the graphics themselves to use with SPX GC! And if you're not familiar with how, you can either purchase the for Professionals version of the software and get a template pack, or go to SPX Marketplace to find the templates to suit your needs. 

Why isn't SPX GC an "app" like all the other apps I have?

Although it is easy enough to use for non-technical users, SPX GC was developed with graphics professionals in mind. Which means that compatibility, reliability, and flexibility are super important in making their workflows as seamless as possible. That is why the app server runs in a terminal and the app UI/renderer in the browser; it's able to adapt seamlessly to each user's environment! We do offer an "app launcher" for Windows/MacOS

What is the free version? Why would I pay money if it's free?

SPX GC is a open-source software, meaning that the source code is free for anyone in the world to view, use, and modify. This enables the application to be enhanced by the community and be used as widely as possible. But we are still a business and it takes a lot of hours and people to provide the best product. The for Professionals version is a way for professional users to support us in the development of SPX GC, as well as provide continuous support, premium features, and more.
