Turnstile , alternative to CAPTCHA from cloudflare

Demo: https://demo.turnstile.workers.dev/

Turnstile is our smart CAPTCHA alternative. It automatically chooses from a rotating suite of non-intrusive browser challenges based on telemetry and client behavior exhibited during a session.

Less data collection, more privacy, same security

Swap out your existing CAPTCHA in a few minutes

You can take advantage of Turnstile and stop bothering your visitors with a CAPTCHA even without being on the Cloudflare network. While we make it as easy as possible to use our network, we don't want this to be a barrier to improving privacy and user experience.

To switch from a CAPTCHA service, all you need to do is:

1. Create a Cloudflare account, navigate to the Turnstile tab on the navigation bar, and get a sitekey and secret key.
2. Copy our JavaScript from the dashboard and paste over your old CAPTCHA JavaScript.
3. Update the server-side integration by replacing the old siteverify URL with ours.

I wanted to use this with Deno Fresh framework, so I created a plugin.

EDIT: shameless self-promotion

I made the plugin MIT and wrote a post about how to use it here: dev.to/khuongduybui/cloudflare-tur...
