Crovly – Proof of Work Captcha & Spam Protection vs ChaLess – Spam Protection Without CAPTCHA

Crovly is a privacy-first captcha service powered by Proof of Work. Unlike traditional captchas that rely on image puzzles (easily solved by AI) or invasive tracking, Crovly makes the visitor’s browser do computational work to prove it’s not a bot. How it works: Your visitor’s browser solves a small cryptographic puzzle (Proof of Work) Browser fingerprint and environment signals are collected (as a hash — no personal data stored) Behavioral analysis detects automated patterns (mouse, keyboard, scroll) A composite score determines if the visitor is human Key features: Privacy-friendly — No cookies, no cross-site tracking No image puzzles — Invisible to legitimate users Resistant to AI vision attacks — Proof of Work cannot be solved by image recognition IP binding — Tokens are bound to the solver’s IP address Adaptive difficulty — Suspicious visitors receive harder challenges 22+ integrations — Works with major WordPress form plugins Lightweight — Widget is under 25KB gzipped, zero dependencies, 42 languages Supported integrations: WordPress login, registration, lost password, comments WooCommerce (checkout, login, register, lost password, pay for order) Contact Form 7 WPForms Gravity Forms Elementor Pro Forms Ninja Forms Fluent Forms Formidable Forms Forminator Jetpack Contact Form Divi (contact form, login) BuddyPress (registration, activity) bbPress (topics, replies) Ultimate Member (login, register, password reset) MemberPress (checkout, login) Paid Memberships Pro Easy Digital Downloads Mailchimp for WordPress GiveWP wpDiscuz wpForo WordPress Multisite signup Shortcode & PHP support: Use [crovly] shortcode in any page or post, or call crovly_render() and crovly_verify() in your theme templates. External services This plugin relies on the Crovly captcha service to function. It connects to two external endpoints: 1. Crovly Widget CDN (get.crovly.com) The plugin loads the JavaScript widget from https://get.crovly.com/widget.js on any page that contains a protected form. The widget runs Proof of Work in the visitor’s browser and collects a hashed browser fingerprint. When: Loaded on frontend pages that display a protected form (login, register, comment, checkout, etc.) What is sent: Standard HTTP request headers (IP address, user agent). No personal data. Terms of Service: https://crovly.com/terms Privacy Policy: https://crovly.com/privacy 2. Crovly Verification API (api.crovly.com) When a visitor submits a protected form, the plugin sends the generated captcha token to https://api.crovly.com/verify-token for server-side verification. When: On form submission of any form protected by Crovly. What is sent: The captcha token (opaque string), the visitor’s IP address (for IP binding), and your Secret Key (for authentication). What is received: A success/failure response indicating whether the token is valid. Terms of Service: https://crovly.com/terms Privacy Policy: https://crovly.com/privacy Both services are operated by Crovly. No data is shared with third parties. The plugin does not set cookies or track visitors across sites.

ChaLess protects every form on your WordPress site from bots and spam — completely invisibly. Real users never see a puzzle, a checkbox, or a CAPTCHA. Bots are detected and blocked silently before the form ever submits. How it works: ChaLess watches how each visitor fills in your forms — timing, speed, and a hidden honeypot field Real humans are let through instantly with no interruption Bots are blocked silently before the form sends Every decision (allowed / challenged / blocked) is logged in your ChaLess dashboard Why no CAPTCHA? CAPTCHAs frustrate real users and reduce form completions. ChaLess works in the background — your visitors never know it is there. What you need: A free account and a site key.

External Services This plugin connects to the ChaLess bot-detection service at silent-shield-saa-s.replit.app to load the protection script and process form submissions. What is sent and when: When a visitor submits a form on your site, the following data is sent to the ChaLess API: Time spent on the page before submitting Time taken to fill in the form Whether a hidden honeypot field was triggered The visitor’s browser user-agent string A session token generated locally in the browser No personally identifiable information (name, email, or form content) is ever sent to the service. Data is only transmitted at the moment of form submission.
