he3.app founder here :)
Thanks for sharing it! I couldn't believe someone shared the tool I built on a website that I browsed a lot.
I'm the founder and also doing the marketing/development. I have dreamt about posting it some date on HN once it is more powerful and popular, but was too shy and busy to do it at the moment.
I'm really happy to see someone else share it which I should have done earlier and maybe more. Thanks again! That really gives me courage to continue the work.
I downloaded it, it has a huge number of random tools to do random things like take a JSON document and make a Java Bean that conforms to the schema, generate UUIDs or make HTML and CSS for a grid or flex layout. I don't know if I'm going to use it a whole lot but it is freaky fast and good looking.<p>For what it's worth it is from a Chinese firm of some sort.
