Formidable Forms

Form builder that doubles as an application and calculator platform

Overview

Formidable Forms is developed by Strategy11, LLC, whose co-founder and CEO is Steph Wells; the company’s site also names WPBeginner founder Syed Balkhi as an advisor.[6] The free edition was listed on WordPress.org in December 2009 and reported 300,000+ active installations in November 2026.[7]

Formidable positions itself as more than a contact-form tool. Its directory page describes contact, payment, survey, quiz, registration and calculator forms as well as complete web applications, and says a developer can turn the same plugin into a data-driven registration system, front-end directory or calculated pricing tool.[7] Formidable Pro adds multi-page forms, file uploads, quiz grading, conditional logic, repeater fields, cascading dropdowns, calculated fields and front-end editing.[7] Its “Views” feature displays submitted data on the front end, which is the basis for listings and directories.

Version 7.0 added built-in MCP support allowing AI assistants to manage forms, entries, styles, actions, payments and subscriptions, and introduced a review queue for suspected spam.[7] A documented cost consideration is the 3% transaction fee on payments in the Basic plan, which the vendor says is removed by upgrading to Business.[6]
