A few years ago I was frustrated with how difficult it was to setup a solid React.js stack with auth, payments, etc so I built a codebase generator at https://divjoy.com
It does around $5-10k a month. Fairly passive. A few hours of support a week. Was full-time on it for the first few years, but decided to join a company recently and keep growing this on the side.
