How is this comparable to StoryPlayX and worldbuilding-centric RP?

Since most tools are character-centric not worldbuilding-centric, I would like to find alternatives. There are FOSS alts like RisuAI or TaleMate, but I want to find something that is robust. https://github.com/kwaroran/RisuAI https://github.com/vegu-ai/talemate
StoryPlayX claims to beat the other competition that are character-based. It seems to be really smooth but their UX on the server/security side is a bit lacking. I wonder what their "secret sauce" is https://www.storyplayx.com/blog/storyplay-x-ai-roleplay/
