Hey HN, I'm quite confused about how software released under the AGPL3 can be also be paid. Let's say I have a front-end library that I want to open source under the AGPL3.

I want to actually sell my software to my customers, so something like 3 tiers: single-site license, multi-site license, SaaS license.

How does this actually work (or does it not work at all)? Wouldn't the AGPL3 license mean that anybody can use my software to build something for free (as long as they also open-source it)?

Would the BUSL make more sense here? I fully understand that this would no longer make it open source though.
