What are the open source options? Turnstile is a replacement for Recaptcha after google moved it from a free product to a paid one.

The main advantage of Turnstile is that is benefits from CFs ubiquity to help judge legitimate vs illegitimate requests.

I would love to know what other options are available in this space aside from Turnstile, Recaptcha and HCaptcha.
