To the point...

The Good

- Super flexible styling: Tweak presets or roll your own styles. Extra stylesheets/scripts give you full control.
- Easy to use: The whole builder is super simple — even I got it fast.
- Layout power: Different element widths make it more than a basic form tool.
- Solid overall UX: Clean, fast, and fun to work with.

The Wishes

- Button controls:- Choose alignment (left/center/right) without custom CSS
- Adjust button size via UI

- Text spacing:- Paragraph/Text padding is a bit large → add small adjustment options (like the page width presets)

- Lists in paragraphs:- List indentation is good, but spacing above a list (e.g., after a heading) gets too big → need a spacer that can increase and decrease gaps

- Editing long text:- Paragraph/Text fields should allow scrolling and/or resizing when content exceeds the visible area (HTML elements already behave better here)

- Headings:- Make H1 a few sizes larger by default

- Payments:- Direct PayPal integration would be fantastic

- Integrations:- MailerLite, Mailchimp, and Moosend would make it a no-brainer

Use Cases

- Marketers and founders who want polished forms fast, without deep coding
- Designers who like fine control via custom stylesheets/scripts
- Teams needing flexible layouts and clean embeds
- And the use cases never ends

Verdict
Deftform is really well done.
It’s flexible, powerful, and dead simple to use. 5 tacos — and 2 more on top to eat right away.
If they add the small polish items (especially spacing controls and button options) plus PayPal and email integrations, it’s an easy recommend for almost anyone.

***Highly recommended***
