# Prosopo Procaptcha
Prosopo Procaptcha is a drop-replacement for reCAPTCHA, hCaptcha, and Cloudflare Turnstile that protects user privacy and collects zero data.
[Sign up for free](https://prosopo.io/register) and get your sitekey today. You need a sitekey to use
this library.
## Get Started
See our [docs](https://docs.prosopo.io) for help setting up Procaptcha on your website or in your app.
## Development Environment
The monorepo for the Prosopo Procaptcha bot protection software includes open source packages associated
with [Procaptcha](https://prosopo.io/products/gdpr-compliant-captcha/).
See [for-devs.md](for-devs.md) for information on setting up your development environment.
[You can run this software as a self-hosted bot protection solution](https://github.com/prosopo/captcha/discussions/1695#discussioncomment-14018903). All of the required software is open source with the
exception of the client-side detection library, for obvious reasons. [Contact us](https://prosopo.io/contact/) if you
need help.
