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).

Why WKAF?

– 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
– Security-focused by default
– Built to scale to high-traffic sites

Who is WKAF built for?

– Developers building performance-focused websites
– Agencies managing multiple client projects
– Production environments requiring reliable data storage
– High-traffic websites

Built for Performance

WKAF stores entries in dedicated database tables with proper indexing.
This avoids performance bottlenecks commonly seen when storing form entries in post meta.
