Standout Differences
Outgrow scores and qualifies leads automatically
Outgrow assigns point values to user answers so leads are automatically qualified and segmented, a lead scoring capability that is not documented for either Fillout or Heyflow.
Outgrow
Fillout syncs natively with Notion and Airtable, on unlimited seats
Fillout's two-way Notion and Airtable sync updates records the instant a form is submitted, and every pricing tier, including free, includes unlimited team seats.
Fillout
Heyflow validates leads for paid traffic
Heyflow's phone number validation and OTP verification filter out low-quality submissions, paired with native Meta and Google Ads integrations built for paid acquisition campaigns.
Heyflow
Outgrow spans the widest range of content types
Outgrow supports quizzes, calculators, assessments, polls, and chatbots, a broader interactive-content range than the form-and-quiz focus of Fillout or the funnel focus of Heyflow.
Outgrow
Branding removal and advanced logic are paid-tier features on all three
Fillout, Heyflow, and Outgrow each reserve branding removal and their most advanced logic or integration features for mid-to-upper pricing tiers.

Pros & Cons
Fillout
Pros
Generous free plan with 1,000 responses per month and unlimited forms and seats, more permissive than many competitors' free tiers.
Unlimited seats on every paid tier removes the per-user cost penalty common in other form builders.
Native two-way sync with Notion and Airtable avoids the latency and extra cost of Zapier-style automation middleware.
Broad feature set (payments, e-signatures, scheduling, PDF generation) reduces the need for separate point tools.
Cons
Paid tiers are gated primarily by monthly response volume, which can require an upgrade sooner for high-traffic forms.
Removing Fillout's own branding requires at least the Pro plan, not available on Free or Starter.
Advanced governance features like SSO and audit logs are reserved for the custom-priced Enterprise tier.
The company's 2025-2026 restructuring under the Zite parent brand may create some confusion for customers researching the company versus the product.

Strong lead-quality tools with phone and OTP validation built in

Cons
Pricing scales with response volume, which can get expensive for high-traffic campaigns
Branding removal and A/B testing are gated behind higher-tier plans
Free plan is limited to only 10 responses per month
Smaller global brand recognition compared to Typeform or Unbounce
Advanced features like custom code require Scale or Enterprise tiers
