In their own words, as submitted to SaaSHub.


nForms is the form backend that replaces two tools developers are tired of gluing together: reCAPTCHA and manual ARIA accessibility code. Shield — Bot Protection SHA-256 Proof-of-Work challenges run in the browser (~200ms). Invisible to users, computationally expensive for bots at scale. No...

As answered by people managing nForms.eu and Cozystack.
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.
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.
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.
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.
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.
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.
