Contao Altcha Antispam

This is a Contao CMS implementation of Altcha. The extension provides a front end form field for the Contao form generator.

ALTCHA uses a proof-of-work (POW) mechanism to protect your forms from spam and abuse. Unlike other solutions, ALTCHA is self-hosted, does not use cookies nor fingerprinting, does not track users, and is fully compliant with GDPR.
