You've overstated the comparative advantages of Sciter so much that, upon clicking through, people might flash back to when they found out was a Segway was and shout, "it's a @#$&-+) scooter?!?"
In particular, it's very weird that "doesn't use native widgets" is presented as an advantage, given that apparently the result is that your apps end up looking like this on every platform: https://notes.sciter.com/
