Ninja Forms

Ninja Forms is a WordPress form plugin built on a free core, and the vendor is pointed about what that means: free in the sense of genuinely usable rather than a trial that prompts an upgrade at every turn. The core includes more than 28 form field types, which it claims is the largest free field selection of any WordPress form builder, so a working form can be built without paying anything. Paid growth happens through add-ons rather than by unlocking basics that were withheld.

The functional set covers the jobs that turn a form into a process. Data calculations handle everything from multiple choice quiz scoring to advanced price calculations inside the form. Unlimited email notifications send any number of emails to any number of recipients per submission, which matters when a single form has to alert several teams. Form actions define what else happens on submission, and submission management keeps the resulting entries organised inside WordPress.

Three features address the problems that arrive once a form is public. GDPR and CCPA compliance tools help meet privacy obligations on data you collect. User restrictions control who can submit, and anti-spam protection filters junk entries. Custom and favourite fields let a team reuse its own field configurations rather than rebuilding them per form. The vendor positions the product as scaling from a simple contact form up to an advanced business workflow on the same installation.
