Reasons buyers look elsewhere

Slack

No alternatives guidance available yet.

Fillout

  • 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
