nForms is the form backend that replaces two tools developers are tired of gluing together: reCAPTCHA and manual ARIA accessibility code.

Shield โ€” Bot Protection

SHA-256 Proof-of-Work challenges run in the browser (~200ms). Invisible to users, computationally expensive for bots at scale. No cookies, no puzzles, no user interaction needed.

Composite scoring combines PoW verification, timing analysis, honeypot detection, and AI spam scoring.

Accessible โ€” WCAG Validation

Add data-validate="required|email" to your fields. nForms automatically injects aria-invalid, aria-describedby, role="alert", and manages focus on errors. WCAG 2.2 AA compliant, EAA-ready since June 2025.

EU-Only Infrastructure

All data processed and stored on Cloudflare Workers, D1, and R2 in Frankfurt. No US data transfers, no tracking cookies, no fingerprinting. GDPR by architecture, not by checkbox.

Pricing

Analysis of nForms.eu

Overall verdict

  • nForms.eu appears to be a form-building/data-collection tool, but without verified, independent details on its current features, pricing, and support quality, a definitive assessment can't be fully confirmedโ€”so approach with reasonable diligence before committing.

Why this product is good

  • May offer a straightforward interface for creating online forms and surveys
  • Could provide customizable templates suited to various business needs
  • Potentially includes data export and integration options for collected responses
  • May offer competitive pricing compared to larger form-building platforms

Recommended for

  • Small businesses needing basic online forms
  • Freelancers or individuals collecting simple survey data
  • Users seeking a lightweight alternative to more complex form tools
  • Teams testing form solutions before committing to premium services

Analysis of Sane Stack

Overall verdict

  • I don't have verified, reliable information about Sane Stack (sanestack.com) to make an informed assessment. I cannot confirm details about its features, pricing, quality, or user experiences, and I don't want to fabricate claims about a product I have no confirmed data on.

Why this product is good

  • I do not have specific, verified information about this product in my training data
  • Making claims about an unfamiliar product could provide you with inaccurate or misleading information
  • The domain name suggests it may be a tech stack, boilerplate, or development tool, but I cannot confirm its actual purpose or quality

Recommended for

  • I'd recommend checking the official website directly for accurate details on features and pricing
  • Look for independent reviews on platforms like G2, Trustpilot, Reddit, or Hacker News for real user experiences
  • Consider reaching out to their support team with specific questions about your use case
  • Check if they offer a free trial or demo to evaluate firsthand before committing

Questions & Answers

As answered by people managing nForms.eu and Sane Stack.

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 โ€” 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 โ€” 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 โ€” 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 โ€” 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 โ€” 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.
