Great post, quite unusual to see something like this but also great to see who else believes in the product. I wonder how you figured out pricing, since I'm working on something that is similar in a few aspects and am trying to figure out how to combine open source and pricing for it.
We chatted to (a lot of) developers/founders to figure out the right pricing structure, and everyone has a different opinion.
However: the most common thing we heard is that it's extremely unlikely to find the right pricing model on your first attempt. It's better to get something out, and iterate. You can then "grandfather" your existing customers - they continue paying the original price while you change pricing for new customers.
Happy to chat more about this if you want (you can find my email in my profile)
