without requiring users to solve visual puzzles or complete complex challenges.

The plugin integrates seamlessly with popular form plugins including:

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

Features:

 * Lightweight and fast
 * No visual puzzles for users
 * Effective spam protection
 * Easy integration with existing forms
 * Customizable difficulty levels
 * Developer-friendly with hooks and filters

### WP-CLI commands

## Cwestiynau Cyffredin

### 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.
