Deftform

Deftform is a clean, no-nonsense form builder from Germany that pairs drag-and-drop simplicity with an AI assistant, conditional logic, Stripe payments and unlimited forms, responses, and teammates for one flat price.

What is Deftform?

Deftform is built by ivy.mayhem GmbH, a small German SaaS company that also runs tools like Eniston, InPrivy, and FeatureShift, and it shows the same lean philosophy across all of them: give people the 90% of features they actually use and skip the bloat. You build forms with a drag-and-drop editor (23 field types including e-signature, ratings, rankings, sliders, and file uploads) or describe what you want and let the AI Assistant draft the fields for you. Forms can be split across multiple pages, show or hide fields based on answers via conditional logic, accept payments through your own Stripe account with no platform cut, and sit on your own domain with SSL and fully custom CSS/JS styling. Where most competitors nickel-and-dime you per user, Deftform includes unlimited team members on every plan, and every package ships unlimited responses with CSV and PDF exports, webhooks, email notifications, and a documented REST API. Direct integrations cover HubSpot, Google Sheets, Airtable, Slack, Discord, MailerLite, Make, and Pabbly Connect. Everything is hosted in Germany with ISO 27001-certified infrastructure providers, GDPR compliance, captcha protection, and a 99.9% uptime guarantee, which makes it an easy recommendation for EU-based businesses collecting customer data. There is no independent review footprint yet — its reputation rests on roughly 96 AppSumo buyer reviews averaging 4.86 out of 5 — and B2B extras like data enrichment and email verification are reserved for a paid Business add-on rather than the lifetime license.

Key Features

• Drag-and-Drop Builder — 23 field types including e-signature, rating, ranking, slider, date/time, and media, with adjustable widths and required-field controls

• Unlimited Team Members — every plan allows as many collaborators as you need with no per-user charges, organized into up to three workspaces (more purchasable)

Who is it for?

• Marketers and lead-gen teams wanting branded forms on their own domain without a Typeform-sized bill
• Course creators and coaches collecting sign-ups, feedback, and payments via Stripe
• Customer support and success teams running CSAT surveys and intake forms
• Small agencies managing client forms across multiple workspaces with several teammates
• EU businesses with GDPR requirements that prefer German-hosted data collection

Who is it NOT for?

• Teams needing deep enterprise survey logic, statistical analysis, or panel management (look at Qualtrics-class tools)
• Anyone who requires a huge native integration library out of the box instead of webhook/Make glue
• Buyers who want B2B lead enrichment included — that's a separate €18/month add-on here
• WordPress users wanting a plugin that lives inside their dashboard rather than a hosted SaaS
