On the Reddit AMA they said to expect the same amount of partnered products in 2026 that they had in 2025. My understanding is that it's still a pretty manual process to integrate things into Beyond. Given the complexity of things like a character builder, I wouldn't expect any sort of open marketplace anytime soon.
As someone on the other end of making such a thing, I agree--I never saw how that would work.
However, I do recall it being brought up. I did a bit of digging and
found it. It was in the 2023 creator summit where they indicated they answered a question during the Q&A:
Q: WIll DDB marketplace be monetized?
A: That is absolutely the intention. Creators can offer their products for sale. Accessible, open, and available to creators.
Obviously that lacks detail, and perhaps they meant something else--it was a quick question and quick answer amongst many--but that explains why it was in the back of my mind.
But yes, adding content to a platform like that requires actual coding, which is why they have to do it, not the content creators. It's not like uploading a PDF, you have to alter the actual code to integrate it into the character builder and character sheet. So I fully agree that it's not a particularly feasible goal.
We get asked constantly whether custom content will be open on our Level Up Gateway platform. Given that it's taken over a year to get the classes up to level 10 and working correctly, the idea that folks could just jump in and 'add' stuff doesn't make sense. I mean, sure you could add the text of a feat or a monster or something, but when you want to
use that content and have it interact with the moving parts of the platform, that's code, not text.
I guess super long term you could design integrated 'wizards' to add different content types, and as long as it does something pretty standard you might be OK, but the moment you want it to do something new or unusual, you're back to writing new code again. Maybe a feat... a full class would be an engineering problem, not a writing problem.
