Drag and Drop Form Builder for Every Type of WordPress Form
Formidable’s drag and drop form maker makes it fast to create any form you can imagine. Start from one of 300+ pre-built form templates, design a completely custom form from scratch, or describe what you need and let the AI form builder generate it for you in seconds. Build a simple contact form in minutes, or layer in conditional logic, multi-step pages, and calculated fields to create sophisticated registration forms, quote forms, and price calculator forms. The form builder is optimized for outstanding speed and server performance, making it one of the fastest WordPress form plugins available.
Unlimited forms are included in the free version, and every form you build is mobile-responsive out of the box. Whether visitors land on your site via desktop, tablet, or phone, your contact forms, survey forms, and payment forms look great and work flawlessly on every device. No other drag and drop form builder for WordPress gives you this depth of functionality starting from the free tier.
Entry Management for Your Free WordPress Contact Forms
Every form submission is stored securely in your WordPress database, so no lead is ever lost. Access entries from the form builder back-end, export to CSV for use in Excel or any other platform, and import leads directly to services like Mailchimp. Formidable is fully GDPR-friendly, giving you controls for IP tracking, saving submissions, and adding GDPR consent fields to any form.
Automate follow-up with customizable email notifications and autoresponders. Set up redirect rules or success messages to guide visitors after form submission. From your first contact form to advanced payment forms and registration forms, every detail of the post-submission experience is in your hands. Built-in invisible SPAM protection keeps your entries clean from bots and spam submissions.
The Only Form Builder Plugin with an Advanced Visual Form Styler
Formidable is the only WordPress form builder with a built-in visual style creator. Match your contact forms, survey forms, and payment forms to your brand in just a few clicks, no custom CSS required. Adjust colors, fonts, layouts, and field styles to create online forms that blend seamlessly with any WordPress theme. For agencies and developers, the visual form styler means you can deliver beautiful, on-brand forms for every client without touching a line of code.
Build Smart Survey Forms and Generate Insightful Reports
With Formidable Pro, you get survey tools that rival SurveyMonkey, without the monthly subscription cost. Build survey forms and poll forms with Net Promoter Score (NPS) fields, Likert scales, star ratings, and image choices. Analyze survey results instantly and display beautiful graphs and charts directly on your WordPress pages and posts. Formidable’s survey form builder makes it simple to gather data, understand it, and act on it, all inside WordPress.
Advanced WordPress Registration Forms for Teams and Events
Formidable goes far beyond basic contact form functionality. The repeater field makes it easy to build comprehensive registration forms for sports teams, events, retreats, courses, and membership sites. Robust marketing integrations and API connections let you funnel registration data to your CRM, email platform, or any other tool in your stack automatically. Whether you’re building an event registration form or a complex multi-step membership application, the form builder handles it.
Payment Forms with Stripe, PayPal, Square, and More
Accept credit card payments, subscriptions, and donations directly through your WordPress forms. Formidable integrates with leading payment gateways including Stripe, PayPal, Square, and Authorize.net. Set up a donation form, product order form, event registration payment form, or service booking payment form in minutes. WooCommerce store owners can build custom product configurator forms with dynamic pricing and calculation fields that feed directly into the WooCommerce cart.
Stripe payment forms are available in the free version, supporting ACH, Cash App, Klarna, iDeal, and more. A transaction fee applies without a Pro license. For in-person events and hybrid businesses, payment forms can be set up for cash, manual payment recording, and on-site collection, giving you complete flexibility for online and in-person transactions.
Build Data-Driven Web Applications with Formidable Views
Formidable Forms is not just a WordPress contact form plugin. It’s a complete platform for building web applications. With Formidable Views, you can display submitted form data on the front-end of your WordPress site, creating searchable databases, directories, event calendars, job boards, real estate listings, member directories, and more. No additional plugin required. The form builder and application builder are tightly integrated, so you can go from form to full application without ever leaving WordPress.
Quiz Forms, Online Calculators, and Calculator Forms
Formidable’s quiz form builder and calculator form builder are industry-leading features that set it apart from every other WordPress form plugin. Build educational assessments, personality quizzes, scored tests, and viral BuzzFeed-style quizzes with ease.

Advanced Fields and Features for High-Converting Forms
Formidable’s form builder includes everything you need to create professional, high-converting forms. Multi-page forms with progress bars boost completion rates. Save-and-continue lets users finish long forms on their own schedule. Cascading dropdowns, conditional logic, partial submissions, and invisible spam protection are all included. Calculated fields power your online calculator forms and instant quote forms automatically.
For developers and agencies, Formidable is the premier WordPress form builder choice. Customize form HTML directly (similar to Contact Form 7, but with full drag and drop power on top). Extend with hooks and filters. Build complex data-driven web applications with low overhead. Formidable supports the most sophisticated projects while remaining approachable for beginners building their first contact form.
With the AI form builder (Pro), you can describe any form in plain text and have it built for you instantly. Need a multi-step registration form, a quote calculator, or a patient intake form? Just type what you need and the AI generates a fully structured, editable form in seconds. You can also add an AI field directly inside any form to display AI-generated responses based on user input, then include those responses in confirmation messages, email notifications, or Formidable Views. Every form is WCAG-compliant and accessible by default, making your forms usable for all visitors.

Formidable Forms Branding Guidelines
Formidable Forms may also be referred to as Formidable, Formidable Form Builder, Formidable Pro, or Formidable Views.
The Best Gravity Forms Alternative, WPForms Alternative, and JotForm Alternative for WordPress
If you’re looking for an advanced WordPress form builder as a Gravity Forms alternative, Formidable Forms delivers more power at a lower price, with a completely free version that Gravity Forms doesn’t offer. As a WPForms alternative, Formidable goes deeper: beyond contact forms into calculator forms, web applications, and data-driven front-end displays that WPForms simply can’t match. Looking for a JotForm alternative or Typeform alternative that keeps your data on your own server? Formidable is the answer. All form data stays in your WordPress database, not on an external SaaS platform. Formidable is also the top Contact Form 7 alternative for anyone who has outgrown CF7’s limited feature set and wants drag and drop power on top. Compared to SurveyMonkey, Formidable Pro delivers professional survey forms, NPS forms, Likert scale fields, and real-time results directly inside WordPress, without a separate subscription. Ninja Forms users looking for more built-in power will find Formidable’s form builder offers calculators, Views, and a web application builder that Ninja Forms add-ons can’t replicate in a single plugin. Fluent Forms and Forminator users who need advanced calculator forms and a complete data display layer consistently upgrade to Formidable.

貢献者変更履歴
6.32
- New: The form listing table now includes new Embeds and List Settings columns, for displaying every post and page where a form is embedded, and an added gear icon for controlling screen options.
- New: The generated Formidable CSS file can now work from the uploads directory instead of the plugin directory. This will automatically work based on the DISALLOW_FILE_MODS constant, and can additionally be controlled using a new frm_add_css_to_uploads_dir filter.
- New: Field errors will now get removed automatically on change events regardless of the JS validation setting.
- Fix: The aria-describedby attribute would not update properly when a form was submitted with errors for fields with multiple inputs.
- Fix: A small styling rule has been added to prevent HTML fields from overflowing past their container when using long strings.
- Fix: Color pickers used on the styler page have been updated to help maintain the active color format, preventing automatic conversions from rgb to hex.
- Fix: Validation for Square has been modified to prevent the submit button from remaining disabled when the Square inputs do not include a postal code input, which happens in some countries including Japan and Australia.
- Fix: A cannot modify header information – headers already sent by FrmTransLiteHooksController.php:108 warning has been fixed.
- Fix: Custom CSS saved in styles would not appear as expected after duplicating, showing additional CSS selectors for the original style.
- Fix: A possible TypeError when calling wp_is_valid_utf8 with a null value has been fixed.
- Fix: A new style would not properly rename when it did not yet have a style ID.
- Fix: PayPal Commerce has been updated to prevent issues where Google Pay and Apple Pay options would not appear if the SDKs had not loaded in time.
- Fix: PayPal Commerce orders and products were not including the payment action description setting.
- The overdue subscription cron message will no longer get logged when there are no active subscriptions.
6.31
- New: Formidable now supports PayPal Commerce. This is built into the Lite plugin. To get started, go to Global Settings > Payments > PayPal to connect your business account.
- New: Form action settings have been redesigned.
- New: Payment actions now use buttons to toggle the selected gateway, and gateway is the top action setting. Note that when custom gateways or Authorize.Net are active, gateways will still revert to the old settings.
- New: The Collect a Payment action icon is now hidden by default, replaced by individual icons for Stripe, Square, and PayPal Commerce. If other gateways are active, Collect a Payment is still included.
- New: Border styling rules have been added so autofill fields in Chrome and Safari will appear more consistent with other fields.
- New: A new frm_after_import_forms action has been added for handling an imported XML after all forms have been imported.
- Fix: A form would incorrectly try to submit a second time when redirecting and submitting with AJAX.
6.30
- New: Product, Quantity, and Total fields are now available in Lite! These are all included in the Pricing Fields section, now located above the Advanced Fields section.
- New: Global custom CSS is now scoped to only style form previews on admin pages to prevent custom CSS from changing the appearance of other elements on the page.
- New: New frm_after_create_entry_{form_key} and frm_after_update_entry_{form_key} actions have been added.
- Fix: When editing an entry, the Other option would not correctly appear selected.
- Fix: Entries would fail to save in some cases where entry names would exceed 255 characters with special unicode characters.
- Fix: Custom style CSS would not properly prefix selectors when ::before or ::after were used.
- Fix: Attempting to refund a Square payment would result in a fatal error when the Stripe or Authorize.Net add-ons were also active.
- Fix: A check has been added to prevent a possible Cannot access offset of type string on string fatal PHP error issue.
