The best free WordPress form plugin for Gutenberg-based sites is Giraforms — it's the only one with native block editor support, built-in submission storage, and multi-layer spam protection in the free tier. For users who want maximum simplicity and don't need submission storage, Contact Form 7 remains the classic reliable option.
With WordPress powering over 43% of all websites on the internet (W3Techs, 2025), there are dozens of form plugins competing for your install. Most promise simplicity but deliver a frustrating maze of locked features and upsell banners. This guide cuts through the noise: we tested five of the most widely used free form plugins on a fresh WordPress 6.7 install and report honestly on what each one actually delivers for free.
How we evaluated these plugins
We assessed each plugin against criteria that matter for real-world WordPress sites: native Gutenberg block editor support, submission storage in the free tier, spam protection, ease of setup, availability of form templates, and the quality-to-price ratio if you eventually need to upgrade.
Every plugin was installed on an identical WordPress 6.7 test site running the Twenty Twenty-Five block theme. We created a simple contact form, a form with file upload, and a form with a select field on each plugin to assess the setup experience, visual quality, and feature parity. Spam protection was evaluated by reviewing the plugin's own documentation and security architecture.
We're the team behind Giraforms, which means this comparison isn't fully neutral — but we've done our best to be factual and fair. We've noted genuine strengths in competing plugins, including cases where they outperform our own product for specific use cases.
1. Giraforms — Best for block editor sites
Giraforms is built natively for the Gutenberg block editor. Every form element — text fields, email inputs, selects, file uploads, submit buttons — is a standard WordPress block. You add them the same way you add any other block: via the + inserter, by typing a slash command, or by dragging from the block library. The form is rendered live in the editor, so what you build is exactly what your visitors see.
The free tier is notably generous: 18+ field types, 10 form templates (contact, newsletter, quote request, survey, and more), built-in submission storage with no companion plugin required, CSV export, email notifications with customizable subjects and reply-to addresses, and multi-layer spam protection (honeypot, submission speed check, IP rate limiting) enabled by default.
Pros: Only form plugin with true native Gutenberg blocks. Stores all submissions without extra plugins. Strong default spam protection. Clean, fast UI. Free tier has no artificial limits on submissions or fields.
Cons: Newer plugin with a smaller community than CF7. Advanced features (multi-step forms, conditional logic, Stripe payments, booking) require Pro at $39/year. Less third-party tutorial content available.
Best for: Anyone using Gutenberg who wants a modern, future-proof form plugin with data ownership built in from day one. Download free from WordPress.org →
2. Contact Form 7 — The time-tested classic
Contact Form 7 has been installed on more than 5 million WordPress sites, and that number is a testament to its reliability and longevity. First released in 2009, it has been the default recommendation for basic contact forms for over fifteen years. It's completely free with no paid tier, no upsell banners, and no artificial limits.
The core experience is shortcode-based. You build your form in a dedicated admin panel using CF7's own markup language, copy a shortcode, and paste it where you want the form to appear. There's no live preview — you see the raw shortcode in the editor and the rendered form only on the front end. For the Gutenberg editor, you'd need to add a Shortcode block and paste the code there.
Pros: Over 5 million active installs (massive ecosystem of tutorials and add-ons). Very lightweight — minimal JavaScript. Zero upsell pressure. Handles basic email-forwarding contact forms perfectly. Well-documented.
Cons: Shortcode-based with no visual editor or live preview. No submission storage (requires the separate Flamingo plugin). Spam protection is basic. No form templates. Not GDPR-compliant by default (no submission log = no data subject access requests). No paid tier means no advanced features ever.
Best for: Sites using the Classic Editor, or anyone who only needs a basic email-forwarding form and already has CF7 running successfully.
3. WPForms Lite — Beginner-friendly with heavy upsell
WPForms is one of the most polished form plugins available, and its free Lite tier is designed to showcase that polish while steering you toward a paid upgrade. The drag-and-drop form builder is genuinely excellent — it's intuitive, the interface is clean, and the onboarding flow helps new users build their first form quickly. There are pre-built templates to start from, though most of the useful ones (payment forms, registration forms, surveys) are locked to paid plans.
The critical limitation of WPForms Lite is submission storage: the free version does not save entries to your WordPress database. Every submission is email-only. If your hosting provider has mail delivery issues, submissions vanish. You must upgrade to WPForms Basic ($49/year) to unlock entry storage.
Pros: Excellent drag-and-drop builder. Good onboarding experience. Well-designed admin interface. Large template library (though mostly paid).
Cons: No submission storage in free tier. Most useful templates require paid plans. Adds noticeable page weight. The free tier feels like a prolonged trial rather than a fully functional product. Starting paid plan at $49/year.
Best for: Users who want the best drag-and-drop experience and are willing to pay for WPForms Pro to unlock the full feature set.
4. Ninja Forms — Flexible but complex
Ninja Forms takes a modular approach: the free core plugin handles form building and submission storage, while additional capabilities (email marketing integrations, conditional logic, multi-step forms, file uploads, payments) are sold as separate paid add-ons. This makes the free tier reasonably capable — you get a builder, entry storage, and email notifications — but the multi-panel interface can be confusing for users who aren't comfortable with a non-linear admin experience.
The builder uses a modal-based workflow rather than an inline editor, which feels dated compared to modern alternatives. That said, Ninja Forms has strong REST API support and is extensible for developers who need to build custom integrations.
Pros: Stores submissions for free. Extensible via add-ons. REST API support. No hard submission limits in free tier. Good for developers.
Cons: Confusing multi-panel admin interface. Most powerful features (email marketing, multi-step, payments) are expensive separate add-ons. Can feel heavy on the front end. Less intuitive for non-technical users.
Best for: Developers building complex form-driven workflows who need extensibility and don't mind the learning curve.
5. Formidable Forms — For power users
Formidable Forms is unlike any other plugin on this list. Its defining feature — available in the free tier — is the ability to display form submission data on the front end using "Views." This means you can build a directory, a job board, a searchable database, or a custom reporting dashboard using Formidable Forms without any custom development. No other major form plugin does this in the free tier.
The tradeoff is complexity. Formidable Forms has the steepest learning curve of the five plugins we tested. The free plan is also relatively limited — calculated fields (one of the plugin's signature capabilities) and most View types require a paid plan, which starts at $99/year — the highest on this list.
Pros: Unique Views feature (display form data on the front end). Stores submissions. Calculated fields concept is powerful. Good for data-driven applications. Entries available for free.
Cons: Steep learning curve. Free plan is limited — most useful Views and field types require Pro ($99/year). Not suitable for casual users. Interface can overwhelm non-developers.
Best for: Developers or advanced users who need to build applications that display form submission data on the front end.

Which free WordPress form plugin should you choose?
