Stop Paying €39/Month for Form Builders You Can't Control
Have you ever needed to add a form to your application but dreaded the complexity? You either had to:
- Pay €39-99/month for a SaaS solution (and give up control of your data)
- Spend hours coding a custom form from scratch (time you don't have)
- Compromise on features to make something "good enough"
Today, there's a better way.

✅ Complete control over their forms and data
✅ Zero cost (no monthly subscriptions)

The Problem We Solved
When you're building a web application, form builders like Typeform, JotForm, or Formspree fall short because:
- You lose control of your data - Submissions go to their servers
- Expensive - €39-99/month adds up fast
- Limited customization - You're stuck with their design system
- Iframe hell - They force you to embed iframes instead of true integration
- Vendor lock-in - Switching solutions is painful
- No API control - You can't handle submissions the way you want
We built SupaForm to fix all of these problems.
How SupaForm Works
The Developer Workflow:
- Design your form visually (drag-and-drop, no coding)
- Copy-paste the code into your application
- Handle submissions in your own backend
- Own your data completely
Why We Built SupaForm
Six months ago, I was frustrated.
Every project needed forms. Every time, I had these options:
- Use a SaaS tool → €39/month × 5 forms = €195/month 💸
- Build custom → 8 hours coding × $50/hr = €400 💸
- Settle for mediocre → Users experience a janky form 😞
None of these were good.
So I asked myself: Why isn't there a form builder designed for developers?
SupaForm was born.
Using modern tools we already love:
- React 19 - Beautiful UI
- TypeScript - Type safety
- Vite - Lightning-fast builds
- Firebase - Serverless backend
