CAPTCHA Alternative 2026: Invisible, GDPR-Compliant Bot Protection

The problem with classic CAPTCHAs

• They interrupt every user (or many users) with a puzzle.
• They can exclude people with disabilities and conflict with WCAG 2.2 and the European Accessibility Act.
• AI and bots can solve or bypass them.
• Some rely on cookies and tracking, raising privacy and consent issues.

The alternative: invisible, background protection

A modern CAPTCHA alternative does two things:

1. Evaluates each request – Before the page is served, your server (or CDN) calls a check-request API (Bot Protection). It gets back allow, challenge, or block. Real users are usually allowed without seeing anything.
2. Challenges only when needed – When the result is “challenge,” the visitor is sent to a short challenge (e.g. proof-of-work or a text/code challenge). Use a solution that is privacy-friendly and accessible - for example taCAPTCHA, which offers proof-of-work (Frictionless) and Code Captcha (text challenge), with no cookies or tracking.

So: no CAPTCHA for real users, and challenge or block for bots and scrapers. That’s the core of an invisible CAPTCHA alternative.
