These monthly HN threads have been great motivation for me to keep building consistently. Thanks everyone!
It's written in elixir using Phoenix live views. There's almost no custom Javascript outside of what that framework gives. First load may take a while because it's the cheapest tier of fly.io and boot loads all known ingredients and products in to memory.
One interesting lesson is to see the effort involved in acquiring new customers and setting up funnels, especially when bootstrapping with a small budget. Sometimes, as developers, we are in our bubbles and don't realize how much skill one needs to figure out the customer acquisition domain.
