Well, you've also got Affinity Designer, which is quite good if you prefer a desktop app with no subscription fees (i.e. proper dekstop app and not an electron app).
Also Adobe XD. I know people give Adobe crap for coming to the party late, but the new tool is quite good with prototyping and web sharing built in, plus they launched freemium model. Framer is great for more advanced prototyping needs w/ animations/transitions/etc, but the XD is pretty good and fast for many needs, and it's Mac + PC.
Somehow that page manages to be just as infuriating as the one for framer. Why do I have to wait for elements to be blended in so I can read them... They should at least make them keep being displayed once they were shown.
