WebKernelAI – Advanced Form Builder

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 postmeta, WKAF uses custom database tables, a schema-driven architecture, and clean AJAX handling to deliver reliable form submissions at scale.

WKAF is designed as a modern alternative to traditional contact form plugins, with a free core and a roadmap for professional add-ons (payments, bookings, integrations).

– Custom database tables (no postmeta abuse)
– Schema-based form engine (single source of truth)
– Clean OOP architecture with strict separation of concerns
– Performance-first design
