Ha! That's my product. Thanks for mentioning!

Hopefully without the latency, it's slow to respond on a 2022 M2 Macbook Air (tried Firefox and Safari)

That's weird. It works perfectly for men much older computers and also on my M2 Mac Pro. What version of OSX are you using? I created that product, btw.

Not OP, but on Firefox 132, Sonoma 14.4, M1 Pro, it's quite janky. It's less so on Chrome and Safari, but it's still noticeable.

On a 3,2 GHz 6-Core i7 Mac Mini with Safari it also feels very laggy and unpleasant to use.
