Eternal Sealed Analyzer is a free and open source site for helping to visualize your sealed pool. As someone that likes to look at the numbers/charts, it really resonated with me watching Kaelos running the numbers on stream to determine the best sealed pool colors. If you appreciate the site and would like to let me know, you can find me on twitter or often in Kaelos's Twitch chat (possibly lurking).
If you encounter a bug with the site or have a feature you would like to see added, please submit it here with as much detail as possible so it can be addressed properly and quickly.
