Is Qeios a good place to publish? Does it have fees?

I am considering where to publish my work. Qeios seems to be a good place since peer review is open and visible.

As far as I can tell, there are no publishing fees. That said, there might be some downsides.

Other options are Springer Nature, ResearchSquare, Publons, Communication Physics, New Astronomy, Elsevier...

My work is the theory of everything.
