Epsilon has a website! It’s https://epsilon.infinitynorm.com/. I didn’t want to get a brand new domain name for it so I decided to use an existing one I’ve had for a while. (You can learn about the infinity norm on Wikipedia.)
I’m the only one using Epsilon at the moment, but as I mentioned on Twitter, I want to run it like a Saas/DBaaS. At the very least, it would be good practice. I also miss running a service solo :). I will open it up for others once I get comfortable with it.
