Drag-and-Drop Form Builder and AI Prompt Assistant

23 Input Field Types: Supports short text, paragraph, email, phone, number, website URL, single choice, multiple choice, dropdown, country selector, opt-in checkbox, rating scales, ranking lists, sliders, date pickers, time selectors, dividers, spacers, hidden fields, eSignatures, and file uploads.
Multi-Page Forms: Break lengthy questionnaires into multi-step pages with progress bars to reduce form abandonment and improve completion rates.
Conditional Display Logic: Show or hide specific fields and form pages dynamically based on prior respondent answers.
File Upload Support: Collect attachments up to 50 MB per file with no overall account storage limits.

Workspace administrators can invite colleagues, freelancers, and clients without incurring additional monthly seat charges. Each account includes three separate workspace slots to organize forms across distinct brands, clients, or internal departments.

Security, Privacy, and Data Management

Hosted strictly on European infrastructure in Germany, Deftform delivers strict compliance with GDPR regulations. The platform incorporates ALTCHA and reCAPTCHA spam protection to filter bot submissions automatically.

Evaluation: Who Should Choose Deftform

Deftform is an ideal form builder for European businesses, agencies, HR departments, and SaaS founders who require GDPR compliance, unlimited response volume, zero per-seat team costs, and seamless Stripe payment collection. It is less suitable for users looking for a free tier. For teams prioritizing data privacy, transparent pricing, and robust automation, Deftform is an exceptional value.
