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.

Anubis is the new hotness, specifically billing itself as an "AI firewall". If you've had an animé waifu check you're human you've even used it.
