Thanks for this detailed response! Yes, the reason I didn't add one is precisely because I'm funding this myself and it needs to make financial sense haha. I don't have VC money to burn through. That said, a compromise could be the OSS tier I had in mind above.

1. Yep, I'll plan to change the free trial to 14+ days. Probably just going to do 30.
2. Ha, well, I somewhat randomly grouped features into different plans since this is my first time doing it. I was roughly thinking about what a "pro" user might want but it's possible I'm off base. The $100 was really for the extra MAUs, but maybe that's the wrong way to ask for $100 and I think you're right that API access might be critical even at 10k MAUs since that's also a lot of users.
3. Yes, I've been thinking about this. Maybe it makes sense to keep the number of MAUs the same on essentials and pro and just offer different features.

Thanks again for this, very helpful and let me know if you have any other thoughts after reading my response
