Reasons buyers look elsewhere
- While Fillout offers analytics, it lacks detailed funnel insights such as question-level drop-off rates found in Typeform
- Compared to Typeform's rich media library (photos, videos, icons), Fillout’s design customization is powerful but lacks built-in multimedia assets
- Some advanced features—like removing branding, larger file uploads, and maps autofill—require higher-tier plans, which may deter small teams
