    Procaptcha – Open-source, privacy preserving and frictionless CAPTCHA▲8

    We built Procaptcha to make sure there's an actually good alternative to Google's ReCAPTCHA that's not a complete nightmare for the end user. Crucially we're not just a giant ad network like almost all CAPTCHA providers [1]. Like with other CAPTCHA providers it's simple to set up, you just change a couple of tags [2]. We've got a few different CAPTCHA types at the moment, all running on a distributed network of nodes with no user tracking. [1] https://prosopo.io/articles/stop-giving-your-website-data-aw...
