Formidable Forms – Contact Form, Survey, Quiz, Payment, Calculator Form & Custom Form Builder

Description

Formidable Forms (https://formidableforms.com/?utm_source=wprepo&utm_medium=link&utm_campaign=liteversion) is a WordPress form plugin, form maker, and quiz maker for contact forms, payment forms, survey forms, quiz forms, registration forms, and calculator forms, plus complete web applications, all built with a drag and drop form builder interface. A beginner can have a working contact form running in minutes. A developer can turn the same plugin into a data-driven registration system, a front-end directory, or a calculated pricing tool. One plugin covers the ground that otherwise takes five separate contact form plugins: forms, payments, surveys, quizzes, calculators, and web apps, all inside WordPress.

Get Formidable Pro and unlock every premium form feature.

Start with the Lite vs Pro comparison.

WordPress Form Builder for Every Type of Form

Start from one of 300+ pre-built form templates, build a custom form from scratch, or describe the form you need in plain English and let the AI form builder create it. A simple contact form takes minutes with this plugin. Layer in conditional logic, multi-step pages, and calculated fields, and the same plugin produces registration forms, quote forms, and price calculator forms. Every form is mobile-responsive by default, and this plugin includes unlimited forms in the free version.

AI Form Builder and MCP: Build Forms with Claude, ChatGPT, Cursor, or Any AI Agent

Describe a contact form or quiz in a sentence and Formidable builds it. The AI form builder (Pro) turns a plain-text prompt into a complete, editable contact form, registration form, or quiz, with fields, validation, and layout already in place. Add an AI field inside any form to show a ChatGPT-generated response based on what a visitor typed, then reuse that text in confirmation messages, email notifications, or Formidable Views.

Formidable also includes built-in Model Context Protocol (MCP) support, free in the plugin. Claude, ChatGPT, Cursor, or any MCP-compatible client can create and edit forms, entries, styles, form actions, payments, and subscriptions directly on your WordPress site from a chat prompt. No separate MCP adapter plugin or Composer setup is required.

Payment Forms with Stripe, PayPal, Square, and More

Accept credit card payments, subscriptions, and donations directly through your WordPress forms. This plugin connects to Stripe, PayPal, Square, and Authorize.net. Set up a donation form, a product order form, an event payment form, or a service booking form in a few minutes.

Stripe and PayPal payment forms are available for free. Stripe supports ACH, Cash App, Klarna, and iDeal. A transaction fee applies without a Pro license. For in-person events, payment forms can also be set to cash, manual recording, or on-site collection, so hybrid businesses aren’t locked into a single workflow.

Survey Forms, Quiz Forms, and Online Calculators

Formidable’s survey form builder covers NPS fields, Likert scales, star ratings, and image choices, then turns the results into graphs and charts on your WordPress pages, without a separate SurveyMonkey subscription. As a quiz maker, it handles scored assessments, personality quizzes, and graded tests.

Calculator forms cover mortgage calculators, loan calculators, BMI calculators, price calculators, and instant quote calculators, all driven by calculated fields that update as a visitor fills out the form.

Build Directories, Listings, and Web Applications with Formidable Views

Formidable is a web application builder as much as a form plugin. Formidable Views turns submitted registration form and entry data into a searchable database you can present as front-end pages: searchable directories, job boards, real estate listings, member directories, event calendars, and timeline views. No additional plugin is required. This plugin’s forms and Views work together, so a form’s data can become a full web application without leaving WordPress, with more built-in depth than Ninja Forms reaches through its own add-ons.

Registration Forms, User Profiles, and Entry Management

The repeater field builds registration forms for teams, events, and courses, with multiple rows of fields for each registrant on a registration form. Front-end profile editing lets users update their own registration form information without visiting the WordPress dashboard.

Every registration form and contact form submission is stored in your WordPress database, exportable to CSV, and importable into Mailchimp and similar services. This plugin includes GDPR controls for IP tracking, saved submissions, and consent fields on any registration form or contact form, along with automated email notifications, autoresponders, and redirect rules after a form is submitted.

Marketing, CRM, and Automation Integrations

Formidable connects contact forms, registration forms, and payment forms to the rest of your marketing stack.

Email Marketing: Direct integrations for Mailchimp, Constant Contact, AWeber, MailPoet, ActiveCampaign, HubSpot, Salesforce, GetResponse, and Campaign Monitor.

CRM and Automation: Zapier connects contact forms, registration forms, and payment forms to thousands of apps, including Zoho CRM, Slack, Trello, and Twilio for SMS notifications.

Newer integrations: Formidable connects to Google Sheets, sends entry data through webhooks to any endpoint, and works with Advanced Custom Fields (ACF) for developers already building with ACF.

WooCommerce: Build custom WooCommerce product forms with variable pricing, configuration options, and calculated totals that flow into the cart.

Multilingual: WPML and Polylang integrations for multilingual WordPress forms.

Analytics and Reporting: Survey results, quiz scores, and calculator entries can all be charted automatically with Charts & Graphs, so a customer satisfaction survey or an NPS survey produces a report without exporting to a spreadsheet first. Combined with Formidable Views, the same entry data can be filtered and displayed as a live dashboard on the front end, for teams that want survey results or quiz completion rates visible to more than just the WordPress admin.

Visual Form Styler and Advanced Fields

Formidable includes a built-in visual style editor, so contact forms, survey forms, and payment forms can match your brand without custom CSS. Adjust colors, fonts, layouts, and field styles in a few clicks.

Pro adds multi-page forms with progress bars, save-and-continue, cascading dropdowns, and digital signatures. Invisible spam protection (honeypot, Akismet, reCAPTCHA, hCaptcha, Cloudflare Turnstile) is included. Address fields are included in the free version, and Google address autofill and geolocation are available with the Geolocation add-on. Every form is WCAG-compliant and accessible by default.

A WordPress Form Plugin for Every Industry

Small businesses use Formidable for contact forms and lead capture. Financial services build loan and mortgage calculators. HR teams and researchers run survey forms and employee surveys, with results charted automatically instead of exported to a separate survey tool. Schools and event coordinators build registration forms. Nonprofits collect donations on a contact form or dedicated donation form. Legal and medical practices use file upload forms for intake. Real estate and job sites build front-end directories. Service businesses handle booking and appointment forms. Course creators and coaches use quiz forms to grade knowledge checks and route students based on their score. Market researchers looking for a Wufoo alternative or a paid SurveyMonkey plan get the same customer satisfaction survey and NPS survey reporting without leaving WordPress. Teams looking for a Formstack alternative for internal request forms find the same calculator and workflow features here, at no added monthly cost. Agencies comparing Fluent Forms or Forminator for calculator forms and a front-end data display layer typically find both together in Formidable.

Formidable Forms vs. Gravity Forms, WPForms, JotForm, and Typeform

If you’ve compared WordPress form plugins, you’ve probably looked at Gravity Forms, WPForms, JotForm, or Typeform. Formidable brings calculator forms, quiz forms, and front-end data display with Formidable Views into one plugin, so you don’t need separate tools for each. Form data stays in your own WordPress database instead of an external SaaS platform, and built-in MCP support lets AI clients like Claude and ChatGPT build and edit forms directly on your site.
