Note that this uses Ultralight which has the following licensing terms:

> Ultralight is free for non-commercial use, educational use, and also free for commercial use by small indie developers making less than US$100,000 a year. You can find full terms in the SDK. Pricing plans for larger commercial projects will be announced later. For more information, email us.

> ... azula can be used as an alternative to Electron.

I'd retitle the project/post as "Lightweight GPU Accelerated Replacement for Electron". That's much more interesting than a GUI for Node.

That Ultralight thing which this is based on looks interesting too. https://ultralig.ht/

I'm doing something similar https://github.com/cztomsik/graffiti/

Can I have a browser based on this Ultralight engine?

Apple's App Store policies state: "Apps that browse the web must use the iOS WebKit framework and WebKit Javascript.". I don't think a fork qualifies.
