# Introduction to ALTCHA for WordPress

The ALTCHA WordPress plugin brings next-level spam protection, seamless WordPress integration, and privacy-first security to your site — without relying on any external CAPTCHA service.

It's built for site owners who want reliable, invisible protection without sending visitor data to a third party.

## Why choose ALTCHA for WordPress?

- **Unlimited verifications** — no quotas, no per-request billing, no third-party dependency.
- **GDPR-compliant and accessible** — no personal data leaves your server, and there's nothing for visitors with assistive technology to solve.
- **Seamless security** — no puzzles or CAPTCHAs. Real visitors pass through unnoticed.
- **Dashboard and activity logs** — see verifications, blocks, and traffic patterns from your WordPress admin.
- **Advanced firewall** — block traffic by country, IP address, or User-Agent.
- **Under Attack Mode** — keep your site responsive during traffic surges or bot floods.

## A better alternative

Unlike reCAPTCHA, hCaptcha, or Cloudflare Turnstile, ALTCHA runs entirely on your own infrastructure — no visitor data is ever sent to a third-party server.
