to your forms. This provides an effective way to prevent spam and bot submissions

 * Contact Form 7
 * Gravity Forms
 * And more coming soon

Features:

 * Lightweight and fast

## Installatie

## FAQ

### How does Pow Captcha work?

Pow Captcha uses a Proof of Work algorithm that requires browsers to perform a computational
task before submitting forms. This is transparent to users but effectively blocks
automated bot submissions.

### Is it compatible with my form plugin?

Currently, the plugin supports Contact Form 7 and Gravity Forms. More integrations
are planned for future releases.
