Thanks for your explanation. AGPL3 sounds nice. I hope my next question doesn't make this more confusing, but in my roadmap for the next months I have a paid subscription plan. Is this still doable with this license?

I guess I'm just overthinking about this problem instead of focusing in the real deal. I have the product in place, I'm preparing a paid plan for the future and after that, release the source code. Shouldn't be that hard to decide. Damn.
