Ninja Forms is a free WordPress form builder plugin. Build contact forms, lead generation forms, calculators, quizzes, surveys, applications, event registration, and booking request forms with a drag and drop builder, or describe the form you want and let the built-in AI form builder draft it for you. Every submission is stored in your own WordPress database, with no limit on forms or submissions and nothing to pay to see them.

The form builder that grows with you

Ninja Forms has been part of WordPress since 2011. It started as a volunteer project for a local nonprofit and today it powers classrooms, clinics, nonprofits, online stores, farms, agencies, and government offices, from a single contact form to advanced business workflows.

The free plugin is the complete product for getting started, not a teaser. Calculations, signatures, star ratings, repeatable field groups, spam protection, submission management, and the AI form builder all ship in core. When you need more, premium features come as individual add-ons you can buy one at a time, and memberships bundle them for the moment when buying them one by one stops making sense. We only grow when the sites running Ninja Forms do.

We also respect your privacy and your time. No unsolicited emails, no aggressive marketing, no paywalling of basic features, and we never see or collect the data your forms collect. Our support team helps every user, free or paid.

Free in Ninja Forms, paid almost everywhere else

Several features that other form builders reserve for paid plans are part of the free Ninja Forms plugin:

Calculations. Assign values to fields and options, combine them with formulas, and show running totals for quotes, order forms, quizzes, and every kind of calculator.
Lead capture. Every submission lands in your inbox the moment it arrives and in your WordPress dashboard for export, with honeypot, reCAPTCHA, hCaptcha, Turnstile, and Akismet spam protection built in.
Signatures. A typed or drawn signature field for agreements, waivers, and applications.
Repeatable fieldsets. Let visitors add another guest, another line item, or another reference without you predicting how many they need.
Star ratings. A clickable rating scale for feedback and survey forms.
Your submissions, on your site. Every submission is saved to your WordPress database. View, search, filter, edit, resend notifications, and export to CSV, for every form, with no entry limit.
AI form builder. Describe the form you want in plain language and the builder drafts it, then refine it in conversation. It runs on the WordPress AI Client with a provider you connect, so your prompts go where you choose.

31 form fields, all free

Text and numbers: Single Line Text, Paragraph Text, Number, Date and Time, Confirm, Hidden
Choices: Single Checkbox, Checkbox List, Radio List, Select, Multi-Select, Select Image, Star Rating
Contact details: First Name, Last Name, Email, Phone, Address, City, US States, Country, Zip
Signature and structure: Signature, Repeatable Fieldset, HTML, Divider, Submit
Spam protection: Anti-Spam, reCAPTCHA, hCaptcha, Cloudflare Turnstile

Customize any field with default values, placeholders, input masks, required and unique-value rules, and custom CSS classes, then save it as a favorite to reuse on any other form.

Emails, confirmations, and actions

Send any number of email notifications to any number of recipients on every submission, each with its own subject, message, reply-to, CC, and BCC, in HTML or plain text.
Show a custom success message (links and download links included), or redirect to any page.
Fire a Google Analytics 4 event on submission for conversion tracking.
Use merge tags to drop field values, calculation results, and site data into emails, messages, and other fields.
Call your own WordPress action hook on submission when you need custom code.

Spam protection on every form

A honeypot is active on every form automatically. Add an Anti-Spam question, Google reCAPTCHA v2 or v3, hCaptcha, or Cloudflare Turnstile when you want more, and run submissions through Akismet if the Akismet plugin is installed on your site.

Privacy tools built in

All submission data stays on your server. Ninja Forms never transmits it and never sees it.
Flag any field as personally identifiable information and choose not to store its value.
Automated export and erase support for the WordPress privacy tools, plus front-end Export Data Request and Delete Data Request actions so visitors can serve themselves.

Control who can submit and where forms appear

Restrict a form to logged-in visitors, reject duplicate values in any field (one submission per email address, for example), or cap the total number of submissions.
Embed a form with the Ninja Forms block, a shortcode, a widget, or by appending it to any post or page.
Share a form by public link with no page at all.
Choose title display, heading level, label position, and what happens after a submission, per form.

Start faster

Nine templates built into the plugin (Contact Us, General Enquiry, Quote Request, Event Registration, Collect Feedback, Questionnaire, Job Application, Export Data Request, Delete Data Request), plus a library of 100 ready-to-import templates on ninjaforms.com, from reservation and food order forms to applications, surveys, and registrations. Download one, import it, and it is ready to edit. Every template page says which add-ons it uses, if any; a few tiles in the plugin’s own picker need a specific add-on and say so when you open them.
Duplicate any form, and import or export forms and favorite fields between sites.
A rich text editor for HTML fields and email messages.

Built for AI agents and developers

Ninja Forms supports the WordPress Abilities API, so an AI assistant connected to your site through the WordPress MCP Adapter can build, edit, and check forms, manage submissions, and change settings through 29 permission-checked abilities, the same operations the dashboard performs. Three destructive abilities stay off unless an administrator opts in. Developers get WP-CLI commands, a WordPress action hook on submission, an extensive filter and action ecosystem, and a full documentation library.

Accessibility

Accessible forms are a core value, not an add-on. Front-end forms are built to our internal standards based on WCAG 2, audited by external accessibility professionals, and regression tested on every update. It is ongoing work; you can read our full Accessibility Statement on ninjaforms.com.

Payments

Accept payments and donations on your forms by connecting your own PayPal account. There is no upfront cost and no monthly fee. Ninja Forms adds a 1.9% per-transaction fee on top of PayPal’s standard processing fees.

External Services

This plugin’s payment features use a connection service at paypal.ninjaforms.com, operated by Saturday Drive, Inc., the makers of Ninja Forms. The plugin contacts this service when you connect a PayPal account and when a visitor makes a payment on your form. It sends the payment amount, the currency, your PayPal merchant ID, and your site’s return address, which the service uses to create the order with PayPal. The contents of form submissions are never sent to this service.
