License is not clear

The license seem to have restrictions for self host? do I need to pay if I self host?

This project is mostly licensed under the GNU General Public License (GPL) as described below. However, certain files within this project are licensed under a different commercial license. These files are clearly marked with the following comment at the top of the file: /* @license Enterprise */
Files with this comment are not licensed under the aGPL v3, but instead are subject to the commercial license terms defined later in this file.

Looking at some of the files, they simply have apolo/graphql - which is MIT -

can you please explain, if I host on my own server, and do not modify any file, can I host and use it for our own company without paying for commercial license??

in the license at the bottom we have this

Hey @maxNodeJs I'm sorry this wasn't clear

can you please explain, if I host on my own server, and do not modify any file, can I host and use it for our own company without paying for commercial license??

Yes, you are free to host on your own server and you should not pay for commercial use. With the current license, you are even allowed to create a competing product and sell it. The only feature that is under the Enterprise license is the single Sign On feature with SAML/OIDC, if you don't use that you're good!
