About nForms

nForms combines bot protection and form accessibility in a single script tag. Its Shield feature replaces CAPTCHA with a SHA-256 proof-of-work challenge that runs invisibly in the browser, uses a single-use nonce and composite scoring, and has a no-JavaScript fallback. The site says it sets no cookies and makes no US data transfers.

The second half is accessibility. By adding data-validate attributes such as required, email or minlength to fields, nForms injects the WCAG 2.2 AA markup automatically, including aria-invalid, alert roles and focus management, so developers do not write ARIA code by hand. Infrastructure runs in Frankfurt, and the interface is available in German and English. The product is in beta, with 100 submissions per month free, Shield Basic included, and no credit card required. It also has docs and pricing pages.
