Questions & Answers

As answered by people managing Private Captcha and nForms.eu.

Who are some of the biggest customers of your product?

nForms.eu's answer:

nForms is in public beta. Early users are solo developers and small agencies in Germany building client websites. The contact form on nforms.eu is a live demo — dogfooding the product.

What makes your product unique?

nForms.eu's answer:

nForms is the only form backend that ships bot protection and accessible form validation in a single script tag. Most tools make you choose — Formspree for the backend, reCAPTCHA for spam, then manual ARIA code for accessibility. nForms handles all three. Zero cookies, zero CAPTCHA puzzles, EU-only data storage.

Why should a person choose your product over its competitors?

nForms.eu's answer:

If you care about GDPR compliance, accessibility, or just hate cookie banners: nForms uses Proof-of-Work instead of CAPTCHA, so there are no cookies and no US data transfers. The same script tag also adds WCAG 2.2 AA validation automatically — no hand-written ARIA code needed. Setup is one HTML attribute, not an npm install or backend integration.

How would you describe the primary audience of your product?

nForms.eu's answer:

Web developers and agencies building static sites, landing pages, or JAMstack projects who need a form backend with built-in spam protection. Especially relevant for EU-based developers who need GDPR-compliant infrastructure and EAA-compliant accessible forms without extra tooling.

What's the story behind your product?

nForms.eu's answer:

I kept adding the same three things to every client site: reCAPTCHA (cookies, US data, consent banners), manual ARIA attributes for accessibility, and a form backend like Formspree. Each solved one problem but created new ones. I built nForms to replace all three with a single script tag — Proof-of-Work for bots, automatic ARIA for accessibility, EU-only infrastructure for GDPR. Solo-built on Cloudflare Workers.

Which are the primary technologies used for building your product?

nForms.eu's answer:

Cloudflare Workers (Hono framework) for the API, Cloudflare D1 for the database, Cloudflare R2 for file storage — all EU jurisdiction. Next.js for the dashboard and marketing site. SHA-256 WebWorkers for client-side Proof-of-Work computation. Resend for transactional email.
