Apple Developer Apps & Services I recently enrolled into paid Apple Developer Program as an Individual.

I'd like to know what otherwise paid apps or services are available for free to members of paid Apple Developer Program?

For e.g., macOS Server.app, which is available as a paid app on the Mac App Store, is available for free via a redeem code to registered Apple developers. I am interested in knowing if there are other paid apps or services (Apple or 3rd party) which I am eligible to obtain for free.

Additionally, what are some of the benefits available only to registered developers, like the ability to contend for WWDC ticket lottery?

Note: What I am interested here in knowing, are the things similar to macOS Server.app which could be obtained by paying, even by non-registered developers, but offered to registered Apple developers for free. I am aware that the various services offered as a part of the paid developer program costs money (technical support incidents, signed certificates), but they cannot be otherwise obtained from Apple by paying and not enrolling into any of the official paid developer programs.
There are no other paid apps given away for free to members.

However, you should be aware that various services/features of the developer membership such as support requests and the ability to generate secure certificates, are things that would otherwise cost money.

In terms of other perks: beta software releases (well, earlier than the public) and developer account tools. macOS Server would count as either/both of those depending on when you visit the member download page.
