underrail.info is an Underrail fansite for info and tools that can't be hosted on the game's official wiki.

The site was started with the character build tool in 2015, as a side project to learn basic HTML5, CSS3 and JS skills. As a challenge, I've tried to get 100% PageSpeed scores on zero-budget web hosting: Everything is well optimized.

This frontpage is served with less than Six kB data transferred total. The character build calculator serves all of its code/data, 4 fonts and hundreds of icons in less than 200 kB transferred. For comparison, the average page load (in 2016) is over 2.5 MB. Simple websites don't need to be bloated!

Tools hosted on this site have no critical server-side code and will work offline if saved or cached locally; your browser does all the heavy lifting.
