Integrate Cap as a CAPTCHA provider

Feature Request

An option to use

https://github.com/tiagorangel1/cap as CAPTCHA would be excellent:

  • Maximally privacy-preserving as it does not rely on off-site behavior tracking for risk assessment.

  • Lightweight and easy to integrate.

  • Self-hostable.

With it being so lightweight, it could potentially be integrated directly into OpnForm, alternatively OpnForm could rely on standalone-mode REST interface and then it would simply be a question of adding a Cap container to the Compose.

    Hi Alexander,

    Thanks again for the detailed suggestion!

    CAP does look like a great option—lightweight, privacy-focused, and self-hostable. We really appreciate you pointing this out, especially with how clearly you've outlined its potential integration paths with OpnForm.

    Noted on all points, and we’ll keep this in mind as we continue exploring ways to improve the platform’s privacy and flexibility.

    Appreciate you taking the time to share this with us!
