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
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.
Where add-ons come in
Some capabilities are add-ons rather than part of the free plugin: conditional logic, file uploads, multi-step forms, payments for order, donation, and event forms, save and resume, layout and styling controls, PDF submissions, user registration, front-end posting, and integrations with email marketing, CRM, and messaging services. Each is purchased on its own, or bundled in a membership .
Form features: Conditional Logic , File Uploads , Multi Step Forms , Layout & Styles , Save Progress , Advanced Datepicker , User Analytics , User Management
Submissions: PDF Form Submissions , Excel Export , Scheduled Submissions Export , Front End Posting
Notifications and automation: Zapier (official partner), Webhooks , Slack , Trello , Help Scout , Twilio SMS , ClickSend SMS
More than a plugin
Free technical support for every user, whether or not you have bought anything, from a team spanning four continents, Monday to Friday. A full documentation library. Regular updates. Translated into more than 24 languages by the WordPress Polyglots community, with WPML as a long-term partner for more. And an ecosystem-aware approach: we know it is not just you and Ninja Forms, so we work to play well with the rest of your site.

Do I have to pay to see my form submissions?
No. Ninja Forms does not paywall submissions. View, search, edit, and export every submission from Ninja Forms > Submissions with the free plugin, with no limit on how many you collect.
Is Ninja Forms free?
Yes. The core plugin is free and open source, and it is the complete form builder: 31 field types, calculations, signatures, star ratings, repeatable fieldsets, unlimited forms and submissions, email notifications, spam protection, privacy tools, and the AI form builder. Premium features such as conditional logic, file uploads, multi-step forms, payments, and integrations are add-ons you can buy individually or as a membership.

Does the free plugin include calculations, signatures, and star ratings?

Can an AI build my forms?
Two ways. Inside the plugin, the AI form builder drafts a form from a plain-language description and lets you refine it in conversation; it uses the WordPress AI Client with an AI provider you connect, and it can be switched off entirely in Settings. Outside the plugin, an AI assistant connected to your site through the WordPress MCP Adapter can build, edit, and manage forms through Ninja Forms’ Abilities API, with 29 abilities available by default and every operation subject to the same permission checks as the dashboard.
Can I build a lead generation form?
Yes. Add the fields you want to collect, and every lead is emailed to you the moment it arrives, stored in your WordPress dashboard, and exportable to CSV, with spam protection built in. Sending leads on to Mailchimp, HubSpot, Zapier, or a CRM is handled by add-ons.
Which features are add-ons?
Conditional logic, file uploads, multi-step forms, payments (PayPal Checkout, Stripe, Authorize.net, Elavon, Recurly), save and resume, layout and styling controls, PDF submissions, Excel and scheduled exports, user registration and login, front-end posting, and integrations with email marketing, CRM, messaging, and automation services. Each is sold on its own or in a membership .
Is Ninja Forms GDPR compliant?
Yes. All user submitted data is stored locally on your server only, unless you expressly configure the plugin to send it elsewhere, for example via an email action. We never see or collect any user submitted data, and we do not act as a Data Controller or Data Processor per GDPR Article 4 for any data submitted through the forms you create. Your forms can flag and choose not to store personally identifiable information per field, and you can automate export or delete data requests .
Is Ninja Forms HIPAA compliant?
Ninja Forms can be and is used on sites that require HIPAA compliance, but overall compliance depends on factors outside the control of any WordPress form builder.
Can I send email with Ninja Forms?
Yes. Any number of emails can be sent to any number of recipients every time a form is submitted. Each email is customized in the form builder, including how the submission data is presented. Emails can include file attachments (with the File Uploads add-on), be sent conditionally , and carry a PDF copy of the submission.
Can I connect Ninja Forms to my CRM or email marketing service?
Yes, through add-ons for Mailchimp, Constant Contact, ActiveCampaign, HubSpot, Salesforce, Insightly, Zoho, and more, plus more than 1,000 other services through the Zapier add-on.
Are there form templates?
Yes. Nine templates are built into the plugin, and the template library on ninjaforms.com has 100 more, each downloadable as a file you import from Ninja Forms > Import / Export and edit like any form. Each template page lists the add-ons it uses, if any.
Can I import and export forms?
Yes. Forms and favorite fields can be exported and imported between sites from Ninja Forms > Import / Export.
Are Ninja Forms forms accessible?
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.
