I rolled out payments on divjoy.com this weekend and got 4 paying users ($240 in revenue). I'm currently charging a one-time fee of $60 to export a React codebase and you get access for 1-year so you can keep coming back and grabbing new components as your product develops.
Still not totally sure about pricing. Might try increasing prices a bit once I roll out Stripe integration and support for Bootstrap and Material UI. Long-term I'd love to re-introduce a free tier. What do you think? My goal is to reach ramen profitable by the end of the year.
