From what I’ve read, mCaptcha is stateful and has higher complexity. It is more geared towards multiple site / app management than single app. While altcha is not free
Oh, I just re read it and altcha is even more complex to integrate if you did not use their ready made service. It is self hostable in the sense that it is just a library to perform said protection. At least if I understood the docs correctly

Altcha is free if you selfhost it.
On their website they have 2 pricing tiers: “Pro” (9€ per month) and “Open Source” (Free)
