There are actually no alternative browser on iOS. Before the European Digital Market Act all iOS browser have to use webkit, so while you could install Firefox, Chrome and others, they were actually using Safari’s rendering engine. I believe that’s where a lot of the limitations come from.
Now with the DMA Firefox could use it’s own rendering engine but this hasn’t landed yet. I don’t know if any other browser has switched from webkit yet.
