WebKernelAI – Advanced Form Builder is a modern, performance-focused WordPress form plugin built for developers, agencies, and production websites.
Unlike traditional form plugins that rely on <code>postmeta</code>, WKAF uses custom database tables, a schema-driven architecture, and clean AJAX handling to deliver reliable form submissions at scale.
