When we started with Vanjaro, we looked at many leading options including elementor for Wordpress. See: https://www.youtube.com/watch?v=CFuoWW9-M60&list=PLLwyyJ9_yNldtZSl_pEIGcko8JNQhSN3U
Interestingly, elementor is open source. See: https://github.com/elementor/elementor
However, it's tightly coupled with wordpress and written in php and thus was NOT an option for us. Regardless, we were amazed with its simplicity and layout and that's the only parallel with Vanjaro. Other than that, Vanjaro has no connection with Elementor.
Regarding where there will be other versions or flavors of Vanjaro then please read the discussion here: https://www.vanjaro.com/conversation/what-is-vanjaro
Our goal is to maintain a single optimized product edition and rely on ancillary services to generate revenue such as SaaS, Support, and Commercial Apps/Modules (similar to current model of Mandeeps.com)
This will allow others to develop blocks & apps and contribute to community either commercially/paid or open source/free.
