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.
