Why CaptchaFox

• Privacy first: built and hosted in the EU, GDPR compliant, no cookies, no tracking
• Easy for people: inline or popup widget, or hidden mode with no widget at all.
• Hard on bots: adaptive bot detection and proof-of-work run in the background, and every answer is verified on your server before Joomla processes the form
• Built for Joomla: uses Joomla's own captcha system integration, so there is nothing to patch and no form to rebuild

Protects your forms

• Contact form, user registration, "Forgot your username?", "Forgot your password?" and article submission in the frontend
• Any other extension's form that uses Joomla's captcha field

Ready for production sites

• Works with Joomla's page cache and a nonce-based Content Security Policy
• Updates through Joomla's update manager
• Open source under GPL, developed on GitHub

Set up in a few minutes

Install the plugin, paste your site key and secret key from the CaptchaFox portal, enable the plugin and choose CaptchaFox as Default Captcha in the Global Configuration. Already using reCAPTCHA? Switching takes that same one setting.
