I'm proud to finally announce Static Ultra! Static Ultra is a pure client-side solution you can use to make a website. It's perfect for Neocities users. In-fact, I'm using it myself right now on the site you're looking at.
There's no point in me repeating all of its features here in a slightly different way. So go learn about it yourself on its website, where there's a full explanation, documentation and a download.
If you have anything to say about Static Ultra, let me know on my Neocities profile!
Enjoy!
