Analysis

An editorial look at what each product does well and who it suits.

Cap Captcha
nForms.eu

Overall verdict

  • Cap (capjs.js.org) is a solid, modern CAPTCHA alternative that uses a proof-of-work challenge instead of tracking users or requiring image puzzles. It is open-source, lightweight, privacy-friendly, and self-hostable, making it a good choice for developers who want a simple bot-mitigation solution without relying on third-party services like Google reCAPTCHA.

Why this product is good

  • Open-source and free, giving full transparency and control over the code
  • Privacy-focused since it uses proof-of-work challenges rather than tracking user behavior or data
  • Lightweight and fast, with a much smaller footprint than traditional CAPTCHA solutions
  • Self-hostable, so you aren't dependent on external providers or their availability
  • No annoying image puzzles for users, resulting in a smoother user experience
  • Easy to integrate with a straightforward API and framework-agnostic design

Recommended for

  • Developers building privacy-conscious applications who want to avoid third-party tracking
  • Small to medium websites needing basic bot protection on forms and logins
  • Projects that prefer self-hosted, open-source solutions over commercial services
  • Teams wanting a lightweight, low-friction alternative to Google reCAPTCHA or hCaptcha
  • Applications where a seamless user experience without puzzle-solving is a priority

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 confirmed—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

  • Users seeking a lightweight alternative to more complex form tools
  • Teams testing form solutions before committing to premium services

Questions & Answers

As answered by people managing Cap 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.
