GateCHA CAPTCHA Wordpress Plugin - Rating, Reviews, Demo & Download
Plugin Description
GateCHA CAPTCHA connects your WordPress site to your own GateCHA instance — a self-hosted, open-source CAPTCHA management service based on the ALTCHA proof-of-work protocol.
Why GateCHA?
- Privacy-first — No cookies, no fingerprinting, no user tracking. Fully GDPR-compliant.
- Self-hosted — Your challenges and verifications stay on your own server. No data goes to third parties.
- Proof-of-work — Bots must solve a computational puzzle. No annoying image puzzles for humans.
- Centralized stats — Track challenges issued, verified, and failed across all your sites from one dashboard.

- Elementor Pro Forms
- Forminator
- Formidable Forms

Setup in 2 steps:
- Enter your GateCHA instance URL
- Enter your API key
That’s it. Enable CAPTCHA on the forms you want to protect.
External Services
This plugin connects to your self-hosted GateCHA instance for CAPTCHA challenge generation and verification. Two API calls are made:
- GET /api/v1/challenge — Fetched by the user’s browser to obtain a proof-of-work challenge.
- POST /api/v1/verify — Called from your WordPress server to verify the solved challenge.
No data is sent to any third-party service. All communication is between your WordPress installation and your own GateCHA instance at the URL you configure in Settings GateCHA.
- GateCHA source code: https://github.com/Upellift99/GateCHA
