Pros & Cons
Forminator
Pros
- ✓Exceptionally generous free version — payments, calculations, conditional logic, and quizzes included at no cost
- ✓Stripe and PayPal payment integrations available for free (most competitors charge for this)
- ✓Built-in polls and quizzes alongside forms — three tools in one plugin
- ✓Strong anti-spam: honeypot, reCAPTCHA, hCaptcha, and Turnstile all included free
- ✓WPMU DEV membership includes the entire plugin suite (Smush, Hummingbird, Defender, etc.)
Cons
- ✗Pro version requires a full WPMU DEV membership — cannot buy Forminator Pro standalone
- ✗No conversational forms or AI form builder
- ✗Heavier frontend footprint (~130KB CSS+JS) compared to lighter alternatives
- ✗Native integrations are limited — HubSpot, Salesforce, Zoho require third-party connectors
Gravity Forms
Pros
- ✓Calculated fields built into every plan (no add-on needed)
- ✓Best-in-class third-party ecosystem (GravityView, Gravity Perks, Gravity Flow)
- ✓All core form capabilities identical across plans — only add-ons differ
- ✓Strong REST API and developer hooks
- ✓Nonprofit pricing ($129/yr for Elite-level) is excellent
Cons
- ✗No free version or trial — requires upfront payment
- ✗Most advanced features (signatures, surveys, geolocation, webhooks) require Elite ($259/yr)
- ✗Third-party ecosystem can make total cost unpredictable
- ✗No AI form builder
- ✗Conversational forms only available at Elite tier ($259/yr)
- ✗Not Gutenberg-native; block merely embeds the classic builder
Kadence Blocks Forms
Pros
- ✓Seamlessly integrated within Gutenberg page building (no context switching)
- ✓600K+ install base gives confidence in stability and updates
- ✓Clean, well-styled forms that match theme design by default
- ✓Free tier handles basic form needs without any add-ons

Cons
- ✗No multi-step forms, payments, calculated fields, user registration, surveys, or quizzes

- ✗Limited integrations compared to dedicated form plugins
- ✗Pro adds good features but at $119+/yr for a form module feels expensive
