Over a weekend during the height of the pandemic, I made a digital school material website that has a "donate" button on it. Totally unexpectedly, it was making $1k/mo via donations. The original hope was to just pay for the hosting costs.
There are options out there but half good build but not good or easy.
I'm working on an e-learning platform that aims to solve a few pain points my sister encounters in her job as a teacher. I'd be curious to hear about your experience.
