The website is entirely client-side based and is open source. There's some janky stuff I had to do (mainly due to CORS) so it could be done completely in JS. However if you see something dumb in the code that can be improved, feel free to submit a PR.

Side note: In case you're curious, I did get emblem copying/stealing to work, but I didn't include it in the website. It was brought to my attention that something like this could harm emblem tutorial makers on YouTube and I didn't want to be responsible for that. If in the future Sledgehammer adds the ability to share emblems on the game then maybe I'll add it to the site.
