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

  • Developer: โ‚ฌ9/month โ€” full PoW, WCAG validation, webhooks

React Complex Tree features and specs

  • Customizability
    React Complex Tree offers a high degree of customizability, allowing developers to tailor the tree component to fit their specific needs. This can be especially useful for creating unique UI experiences.
  • Feature-Rich
    The library includes a wide range of features out of the box such as drag-and-drop support, keyboard navigation, and dynamic data loading, which can save development time.
  • Accessibility Support
    React Complex Tree is designed with accessibility in mind, providing support for ARIA attributes and keyboard interactions, which helps ensure that applications are usable by people with disabilities.
  • Performance
    The component is optimized for performance, handling large data sets efficiently without significant slowdowns, which is critical for applications that manage extensive hierarchical structures.
  • Community and Documentation
    The library has a supportive community and well-structured documentation, providing developers with ample resources to troubleshoot and extend its functionality.

Possible disadvantages of React Complex Tree

  • Complexity
    Due to its extensive features and customizability, React Complex Tree can be complex to set up and configure properly, which may lead to a steeper learning curve for new users.
  • Bundle Size
    As a feature-rich component, React Complex Tree can increase your bundle size, which might be a concern for projects where performance and loading time are critical.
  • Third-Party Dependency
    Relying on a third-party library introduces dependencies outside of your control, which may present challenges in terms of long-term maintenance and potential update or deprecation issues.
  • Specific Use Case Tailoring
    While it offers a lot of features, developers may find that very specific use cases require additional effort to customize or extend the component beyond its intended use.

Questions & Answers

As answered by people managing nForms.eu and React Complex Tree.

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.
