Best Form Builders for Your Website in 2025

Need to add a form to your website? Whether it's a contact form, registration form, survey, or lead capture form, you've got options.

Here are the 5 best form builders in 2025, ranked by flexibility and value.

What Makes a Good Form Builder?

A good form builder should:

• Let you create the exact form you need
• Work seamlessly on your existing website
• Match your brand design
• Handle validation and logic correctly
• Be affordable for your use case
• Provide reliable data collection

Different builders take different approaches. Let's break them down.

1. Embeddable: Fully Custom AI-Built Forms

Best for: Custom forms that don't fit templates.

(Embeddable)[/] takes the AI approach: describe the form you want in plain English, and it builds it exactly to your specs. No templates, no limitations, just 100% customizable forms.

Why Embeddable for Forms

Build Anything Need a multi-step registration form with conditional logic? A survey with custom validation? A contact form with file uploads? Just describe it and the AI builds it. No "this template doesn't quite work" compromises.

Perfect Brand Match Give Embeddable your website URL and it automatically matches your colors, fonts, and design style. Your form looks like it was custom-coded for your site.

Embed Anywhere or Use Standalone Get an embed code for your website, or use it as a standalone page with your custom domain. Total flexibility.

Fast Changes Need to add fields or change the validation rules? Just chat with the AI. Updates happen in seconds, not dev sprints.

Pricing

• Free: 25 tokens/month to try it out
• Paid plans: Starting at $19/month

Choose your plan based on usage needs.

Browse free form templates and customize them with AI to match your exact needs.

2. CommonNinja: Template-Based Form Builder

Best for: Quick forms from proven templates.

CommonNinja's form builder gives you pre-styled templates you customize with a visual editor. Great if your form fits a standard pattern.

Why CommonNinja for Forms

Pre-Built Templates Start with templates for contact forms, registration forms, surveys, and more. Customize fields, validation, and styling to make it yours.

AI Editor CommonNinja includes an AI editor for faster customization when you need to go beyond basic template tweaks.

Affordable At $2/month starting price, it's one of the most budget-friendly options if you need multiple widgets.

The Tradeoff

Templates work great for standard forms but can feel limiting if you need something unique or highly customized.

Pricing

• Free: Basic access
• Paid plans: Starting from $2/month

Price increases based on how many widgets and features you need.

3. Jotform: Comprehensive Form Platform

Best for: Feature-rich forms with extensive integrations.

Jotform is one of the most established form builders with thousands of templates and powerful features for complex forms.

Why Jotform

Massive Template Library Over 10,000 form templates across every industry and use case. If it exists, there's probably a template for it.

Extensive Integrations Connect to 100+ apps and services including payment processors, CRMs, and marketing tools.

Advanced Features Conditional logic, calculations, payment collection, e-signatures, and HIPAA compliance options.

Team Collaboration Multiple users can work on forms together with role-based permissions.

The Catch

The free plan is quite limited, and Jotform's interface can feel overwhelming with so many features. Pricing scales quickly as you need more forms and submissions.

Pricing

• Free: 5 forms, 100 monthly submissions, 1 user, 100 MB storage, 1,000 monthly form views, 500 total submission storage, 100 fields per form, 10 monthly payment submissions, 10 monthly signed documents

Jotform branding appears on free forms. HIPAA compliance features unavailable on free tier.

4. Fillout: Modern Form Builder

Best for: Clean, simple forms with generous free tier.

Fillout combines simplicity with powerful features, offering one of the best free tiers in the form builder market.

Why Fillout

All Question Types Access to all question types even on paid plans, including multiple choice, dropdowns, file uploads, and more.

Custom Branding Remove Fillout branding and add your own custom themes, share links, and even custom CSS on higher plans.

The Tradeoff

While the free tier is excellent, you'll need paid plans for higher response volumes and advanced features like custom domains.

Pricing

• Free: Unlimited forms, unlimited seats, 1,000 responses/month, all the basics
• Starter: $19/month (everything in Free, all question types, 2,000 responses/month, custom endings, custom themes, redirect on completion)

• Business: $89/month (everything in Pro, form analytics, unlimited responses, custom domain, partial submissions, custom code, priority support)

5. involve.me: Interactive Form Funnels

Best for: Forms as part of lead generation funnels.

involve.me focuses on interactive forms within multi-step experiences and funnels. It's more than just a form builder, it's a lead gen tool.

Advanced Analytics Track completion rates, drop-off points, and conversion metrics to optimize performance.

The Catch

involve.me is priced for marketing teams running lead generation campaigns, not just simple website forms. You're paying for the full funnel-building platform, which can be expensive for basic form needs.

Pricing

• Starter: $49/month (5 live funnels, 1 user access, participant emails, conditional logic, 50+ content elements, 30+ integrations)
• Pro: $99/month (15 live funnels, 3 users included, everything from Starter, remove watermark, hidden fields, detailed funnel analytics)
