Gravity Forms vs Ninja Forms: Which WordPress Form Builder is Best?

(Last Updated On: October 6, 2018)

If you’re looking for an advanced form builder for your WordPress site, there’s only a handful that are worth mentioning.

Currently, Gravity Forms and Ninja Forms are by far the most popular.

Gravity Forms has been around longer, but Ninja Forms was created as a form builder that took a different approach.

So which one is better?

Let’s find out. I’ve done a head-to-head comparison of all major aspects of an advanced form builder, broken down by category.

My goal with this comparison review is to make it crystal clear which form builder is better suited for your situation.

Pricing and Plans

Cost is often the biggest factor when choosing to buy a new tool.

The only way to use Gravity Forms is to buy a plan on a yearly basis.

Ninja Forms is similar, in that they offer 3 plans, all on an annual basis. However, they also have a free plan that contains their powerful core form builder. It doesn’t have any extras, but is much better than most other free form builders.

Assuming you need advanced functionality, like being able to integrate with an email marketing tool, or allow file uploads, let’s take a look at the paid plans.

I’ve put together a summary table of the plans each tool offers, along with the main features on each plan. Each tier higher includes everything from the plans below it.

Gravity Forms Ninja Forms
Basic Pro Elite Personal Professional Agency
$59/year $159/year $259/year $99/year $199/year $499/year
1 site 3 sites Unlimited sites 1 site 20 sites Unlimited sites
Conditional Logic Pro add-ons (mainly chat and CRM integrations) Elite add-ons (polls, quizzes, Stripe, and more) 20% discount off add-ons 40% discount off add-ons All add-ons included
Standard Support Priority Support Standard support Better support Priority support
Email marketing add-ons WordPress Multi-Site Conditional Logic Email marketing integration
Multi-Page Forms Multi-Page Forms PDF form submission
File Uploads File Uploads

At each level, Ninja Forms is more expensive than Gravity Forms, even though they offer similar features. So if price is your main concern, Gravity Forms will almost always be your best choice.

But the quality of features is also important, perhaps Ninja Forms is worth the extra cost. That’s what the rest of this review will look at.

A Few Notes About Gravity Forms Pricing

As mentioned, there’s no free plan, or even free trial to try out Gravity Forms.

However, you can create your own demo site that comes fully stocked with all available add-ons. The demo site is a basic WordPress site that will let you get familiar with how Gravity Forms feels and works. Of course, you can’t use the forms you create here on your actual site, this is just a testing ground.

The demo site lasts for 7 days after you stop logging in to it.

Finally, Gravity Forms does have a refund policy, which lets them give refunds on a case-by-case basis. But there’s no formal money-back guarantee, which is why it’s a good idea to make sure you like the demo version first.

A Few Notes About Ninja Forms Pricing

I highly recommend installing the free Ninja Forms plugin on your site and giving it a try. It contains the core form builder, and dozens of fields that you can add to it.

If you end up liking it, you can purchase a license and paste it into the settings while retaining any forms you’ve created.

Ninja Forms also offers a 14 day money-back guarantee.

Finally, the most important thing about Ninja Forms is understanding their extensions (sometimes referred to as “add-ons”). With the free plan, you can purchase add-ons individually, so you only get the features you need.

But they’re still pretty expensive, which is why it usually makes sense to buy one of the plans we looked at. These come with a bundle of popular add-ons, and it works out to a much cheaper price than buying them individually.

For instance, you’ll see in the table that email newsletter integration (e.g. MailChimp, AWeber, etc.) are only part of the agency plan. But that doesn’t mean that you can’t buy the MailChimp (for example) add-on individually on top of any one of the other plans (including the free one).

Ninja Forms is very flexible, and can cost less if you need very specific add-ons that Gravity Forms only offers in their highest tier plan(s).

Installation and Ease of Use

Beyond features and price, it’s important that tools are easy to use. Otherwise you waste your time and can get frustrated.

A good tool feels good to use, and is intuitive. Let me quickly go over how to get up and running with both plugins before we dive into the features.

Gravity Forms

Once you purchase one of Gravity Forms’ plans, you’ll be given a plugin file to download.

You can upload this in your WordPress plugin section like any other plugin:

Gravity Forms Plugin

Once installed and activated, you’ll find that there’s a new “Forms” menu option along your side menu.

Gravity Forms Menu

The default screen is a page of all your forms, where you can see a table of how many entries, views, and conversions each one has had. You can also click on them to edit them, or create a new one using the “add new” button on the page.

Pretty straightforward and intuitive so far.

Ninja Forms

You’ll find Ninja Forms with a simple search in the plugins tab of your WordPress backend:

Ninja Forms Search

Since it’s so popular, it’s not hard to find. This is the free version for now. You can input a paid license number later.

Install and activate it, and you’ll see a new menu option called “Ninja Forms” on the left sidebar.

Ninja Forms Menu

Again, the dashboard has a list of any forms you’ve made.

Both plugins are easy to get started with, although Ninja Forms’ interface is a bit prettier.

Core Form Builder Comparison

Arguably the most important part of each plugin is how easy it is to create a form.

So let’s go over how intuitive the core form builder is.

Gravity Forms

Clicking the “add new” button at the top of your dashboard will open up the form editor.

By default, the page has detailed instructions with images, which is great for your first few times.

All the fields are located on the right panel menu. You can drag any field over to the left side to actually build your form.

Gravity Forms Preview

Here’s a brief preview of the editor:

There are dozens of fields you can add to your form.

Clicking on a field on the left panel will let you edit it. You have full control over text, and can add a custom CSS class to it.

Gravity Forms Editor

You’ll notice that your form is rather blank.

That’s because it’s designed to inherit styling from your theme, which it can’t do in your WordPress backend.

At any time you can click the preview button to load a new page that shows you what your form looks like with styling applied.

Gravity Product Order Form

If you have an attractive theme, the form will likely look good as well.

However, there’s no easy way to alter the CSS from the plugin itself, so you’ll need to know a bit of CSS yourself if you’d like to change the appearance.

Finally, to insert a form onto a post or page, you use the new “add form” button above the standard WordPress text editor. You simply pick your form from a dropdown menu:

Gravity Insert Form Page

Overall, building a form is quite simple, although having simpler styling options would be nice.

Ninja Forms

Ninja Forms also has an “add new form” option from the dashboard.

One big difference is that you can choose from a variety of templates (or start from scratch).

Gravity Forms Blank Form

These templates come with fields already added to your form, although you can edit them in any way you’d like.

The form editor is similar to Gravity Forms, with your form on the left, and fields on the right:

Ninja Forms Screenshot

The interface is much cleaner and usable, and the form preview shows the styling that Ninja Forms applies to all forms by default.

When you click an element on your form, it will open up an options panel on the right where you can edit text, change the appearance, and even add custom CSS classes to individual elements.

While you’ll still need to know CSS to make further styling changes, it’s simpler in Ninja Forms, and you have more finite control over element appearance if needed.

Finally, under the advanced section of the new form page, you can change default display settings, add restrictions, or access any advanced add-ons you’ve purchased (more on that later).

Ninja Forms Display Settings

To add a form to a post or page, you have 2 options.

The first is the same as Gravity Forms, using the newly added button above your text editor to pick a form from a dropdown list.

The second is to add the form shortcode manually, which you’ll find beside each form on your dashboard.

Overall, both form creators are simple to use and will work without causing much frustration for most users.

However, I’d give Ninja Forms the slight edge here based on its cleaner user interface, form preview, and extra control over CSS classes.

Integrations With Other Tools

Integrations are crucial for “advanced” forms, since you’re dealing with features like email marketing and payment, which require other services and functionality.

Both Gravity Forms and Ninja Forms offer a reasonable sized library of add-ons.

Gravity Forms

In WordPress, you can manage add-ons in the “add-ons” menu option.

Depending on the plan you’re on, you’ll see different add-ons that are available to you. You can activate the ones you want to use, since you likely won’t need them all.

Gravity Forms Add Ons

When you go into the settings menu for Gravity Forms, you’ll see all activated add-ons in the left panel of the screen:

Gravity Forms General Settings

You’ll need to go through each one and follow the instructions to get an add-on to work.

In most cases, you just need to copy and paste API keys from the tool you’re trying to connect to.

Gravity Forms Stripe Settings

What Integrations Does Gravity Forms Support?

You can find a full list of integrations here.

Alternatively, here’s a list of current add-ons, divided by the plans that they come with.

Basic Plan Pro Plan Elite Plan
ActiveCampaign Agile CRM Authorize.net
AWeber Batchbook Chained Selects
Campaign Monitor Breeze Coupons

Twilio
Zapier
Zoho CRM

Note that Gravity Forms may add new add-ons in the future, so if you’re looking for a specific one that isn’t here, double check their official website.

Ninja Forms

Ninja Forms was created with the idea of add-ons in mind. Instead of paying for features you don’t need, you can buy each individually if you’d like.

Ninja Forms Add Ons

Some of these are bundled together in the paid plans.

If you buy them individually, the prices range from $29 to $129 per year, depending on the specific plugin, and how many sites you need it for.

Ninja Forms Add On Pricing

Add-ons are just additional WordPress plugins. When you buy new ones, you’ll be given a zip file to upload to your WordPress sites.

Activating a plugin will add new options to the main Ninja Forms interface, you won’t actually have to go into each individual add-on plugin to use it.

What Integrations Does Ninja Forms Support?

Ninja Forms actively adds new extensions to their catalog, so it’s a good idea to take a look at their official extensions page.

Most are similar to Gravity Forms, but both tools have a few integrations that the other doesn’t.

Here’s a list of the current most popular Ninja Forms add-ons:

  • Conditional logic
  • Multi-part forms
  • Front-end posting
  • File uploads
  • Layout and styles
  • MailChimp
  • Campaign Monitor
  • Constant Contact
  • AWeber
  • PayPal Express
  • Stripe
  • Trello
  • Zapier

Reporting, Data and Statistics

It’s one thing to make a form, but you also need to be able to access the data you collect.

It’s also convenient to see basic stats for forms like how many views and entries it’s received, instead of having to try and cross-reference your site analytics (e.g. Google Analytics).

Let’s see what both offer.

Gravity Forms

Gravity Forms offers this data right on the dashboard.

Beside each form is the number of entries, views, and conversion rate (entries divided by views).

Gravity Forms Bulk Actions

Clicking the “entries” plugin menu option, or the “entries” link that appears when you hover over a form title on your dashboard will load a new page of entries.

Gravity Functions Entries

The base entries form is just a summary, but clicking one of those entries will load another page with full details:

Gravity Forms Payment

If you’ve installed any payment integrations (e.g. PayPal), there will be a separate reporting tab for sales.

Gravity Forms Product Forms

This will give you a graph of orders over time, plus a table underneath of all the individual orders.

Overall, Gravity Forms has all the data and analytics most people will need.

Ninja Forms

The only way to view submissions in Ninja Forms is through the “submissions” menu option:

Ninja Forms Submission

It shows you all the entries in table form, but that’s it.

It meets the minimum requirements for form analytics in a plugin, but could be improved.

Advanced Features and Add-ons

Several extensions for both Gravity Forms and Ninja Forms aren’t integrations with other products, but extra functionality in the form of advanced features.

I can’t go through all of them here, but both share certain popular advanced features.

Conditional Logic

Conditional logic lets you create dynamic forms.

If a certain trigger condition is met, you can specify an action.

For example, you can use it to displace certain fields depending on the option a user picks from a dropdown menu.

Gravity Forms Example

When you expand a field in the Gravity Forms form builder, there’s an option to enable conditional logic in the advanced tab.

Gravity Forms Builder

It’s reasonably straightforward. You can show or hide that specific field based on any the activity for any other form field so far.

In Ninja Forms, you can do the exact same sorts of things:

If you have the conditional logic plugin, you’ll find its settings in the “advanced” tab of the form editor.

Gravity Advanced Tab

The interface is much prettier than in Gravity Forms, but the elements are virtually identical:

Gravity Forms Condition

You define a condition based on one field, and that can be used to specify what should happen to fields later on.

It’s a bit more intuitive of a layout than Gravity Forms, and its nice to see all conditional logic in one place, so I’d give a small edge to Ninja Forms here.

Multi-Part Forms

Dividing forms up into multiple smaller pages can improve conversion rates, since it seems like less work to users.

In Gravity Forms, there’s a “page” element in the standard fields section that you can drag onto your form.

Putting this field anywhere in your form creates a new page, and you can have as many pages as you’d like:

Gravity Start Paging

When you preview it, you’ll see that a “next” button has been added at the bottom of your form instead of a “submit” button.

There’s also a progress bar that shows how many pages you’ve added.

Gravity Forms Progress

In Ninja Forms, you’ll need an add-on to create multi-page forms.

If you have it, you’ll see a grey plus sign in your form builder. Each time you click this, a new page is added:

Ninja Forms Multi Page

When you add new pages, a page navigation menu is added to the bottom. This makes navigating between pages on a long form easier than in Gravity Forms, which would require tons of scrolling.

Ninja Forms Navagation

Both plugins make it easy to add multiple pages, and the end result is the same. No big edge either way unless you like the look of one approach more than the other.

Spam Protection

If you’ve ever created a basic HTML form of your own, you know that you’ll be flooded with spam submissions made by bots if you don’t implement protection.

Both Gravity Forms and Ninja Forms offer reCAPTCHA.

In Gravity Forms, there’s a “CAPTCHA” field you can drag onto your form under “advanced fields”. It ends up looking like a standard human check:

Gravity Forms Captcha

In Ninja Forms, this feature is included on the free plan.

You can find is under “miscellaneous fields”:

Ninja Forms Recaptcha

Both offer good spam protection through this feature, and there’s no big difference between the two plugins here.

File Uploads

Most sites that rely on user-submitted content need to allow users to upload files. Both of these plugins offer the ability to add file upload buttons to forms.

In Gravity Forms, there’s a “file upload” in advanced fields.

By default it’s not the prettiest option, but it works.

Gravity Forms File Upload

The file will be saved on your WordPress server, but you can also use an add-on (like the Dropbox Add-on) to upload the file to a third-party server instead.

If you have the file uploads add-on in Ninja Forms, you will see the “file upload” field under the common fields in the form builder.

Ninja Forms File Upload

You can choose to save to your media library, or save the file to an external service.

Again, virtually identical.

Calculations

Sometimes it’s nice to create dynamic fields based on calculations.

For example, you could create a project estimate form that takes in the number of hours someone would like to hire you for, and show the user an estimate based on a simple calculation.

In Gravity Forms, calculations can only be made based on number fields.

Once you have multiple number fields, you can add a third one and choose the “enable calculation” option.

Using the “insert merge tab” option, you can insert the values of those previous fields, and apply basic operations to them:

Gravity Forms Calculations

For this example form I simply multiplied the first 2 number fields together.

Ninja Forms Calculations

When a user enters the first 2 number fields, the total is automatically updated.

Ninja Forms also offers calculations as an add-on.

The calculations can be based on any fields that accept a number input (not just “number” field inputs).

You’ll add calculations through the advanced tab of your form:

Ninja Forms Advance Tab Calculations

To use it, you create a variable name that will be the result of some calculation based on existing fields:

Gravity Forms Advanced Tab

The process looks very similar as in Gravity Forms.

To use the value, you’ll have to add an HTML form to your field and insert that variable name in curly braces.

Ninja Form Document Calculations

The NInja Forms documentation on calculations is very good, and you’ll need it the first few times.

Calculations in either plugin aren’t exactly intuitive, but also not too complicated once you understand them. There’s no big differences here.

Multi-Column Layouts

Finally, a common feature it to put smaller fields together in a row to minimize space needed.

This is not included in Gravity Forms, but you can use an unofficial third-party plugin to enable this functionality.

In Ninja Forms, this feature is included in an add-on. It lets you easily put two or more fields in a single row:

Ninja Forms Multi Column

If this is a feature you’re looking for, I’d suggest going with Ninja Forms, which you don’t need to rely on an unofficial plugin for.

Customer Support

I’ve found that when using any sort of “advanced” tool, there are many times where things don’t work as they should.

That’s why good support is important.

Gravity Forms

Gravity Forms doesn’t offer any phone, chat, or email support.

If you really need help, you can open a ticket, but you’re not getting immediate help.

Your other option is to try and find an answer in the documentation. Some of it can be found in the “help” section of the plugin itself:

Gravity Forms Documentation

For some reason, you’ll find way more documentation on the Gravity Forms website itself.

The articles themselves are well-written, but there’s not very many of them. Few contain any troubleshooting instructions or guides to unique cases. So if you run into a strange problem, a ticket is your best bet.

Overall, those are some weak support options.

Ninja Forms

You can submit a support request (email/ticket) through the plugin backend if you need help:

Ninja Forms Help

But support is only available Monday through Friday, from 8 AM to 4:30 PM EST.

Just like Gravity Forms, you’ll likely end up at the documentation.

I’m impressed by Ninja Forms’ knowledge base. They have high quality video walkthroughs of well over 50 topics:

Ninja Forms Walkthroughs

They also have well-written guides to doing a wide variety of things, with detailed instructions and clear images.

So while the live support options are still weak, the documentation is very good. Both Gravity Forms and Ninja Forms could improve in this area, but I’d give Ninja Forms the edge.

Gravity Forms vs Ninja Forms: Which Should You Choose?

It should be clear that both plugins are solid form builders and offer most of the functionality that you’ll ever need.

So which one is right for you?

Let’s summarize each section one last time:

Aspect Winner Reasoning
Pricing Gravity Forms Gravity Forms is usually cheaper. However, Ninja Forms lets you buy individual plugins, so it can work out to be cheaper if you only need 1 or 2 specific features. Ninja Forms also offers a free plan, Gravity Forms does not.
Installation No winner Both are easy to get up and running.
Core form builder Ninja Forms (slight winner) Both are simple to use and offer a wide variety of fields. Ninja Forms has a nice user interface, and gives you more control over CSS classes of elements.
Integrations No winner Both offer a wide variety of integrations with email marketing tools and CRMs. However, Ninja Forms is continually developing more, so they may have the better library in the future.
Reporting Gravity Forms Ninja Forms shows you entry data, but nothing more. Gravity Forms shows you views and entry statistics on the dashboard and offers a bit more insight.
Advanced Features No winner Both offer all the most common advanced features that most users will need.
Customer support Ninja Forms Both could stand to improve on their live support options. However, the Ninja Forms documentation is excellent, while Gravity Forms’ documentation could be improved.

There’s no clear winner to me in this head-to-head matchup. Of course, you may also just prefer the look and feel of one over the other.

If I had to pick an overall winner, I’d go with Ninja Forms. Their interface is cleaner and a bit easier to use, and certain advanced features are also a bit easier to use.

If you don’t have a clear choice in mind at this point, I’d recommend breaking down the advanced features you need, and then seeing how much it would cost for each tool.
