Fluent Forms — a WordPress form builder on 700K+ sites

Fluent Forms is the WordPress form builder I build and lead engineering on at WPManageNinja. It runs on 700K+ active sites, and the free plugin is public on the WordPress.org plugin directory.

Unlike the standalone tools I own end to end, this is product work at scale — I’ve architected and maintained large parts of it: the form engine, payments, conversational forms, quizzes, inventory, and save-and-resume, plus validation across PHP / JavaScript / REST and a long list of third-party SaaS integrations.

Why it’s here

Most of my day-to-day engineering lives in this codebase, and much of what I write about — backward compatibility, migration safety, and the cost of a small shortcut across hundreds of thousands of sites — comes straight from maintaining it.
