Trusted by enterprises
An enterprise CAPTCHA built for complex infrastructure, not just websites
Privacy-first, zero-PII architecture
MTCaptcha uses background Proof-of-Work and request-metadata analysis instead of user tracking.
With no tracking cookies and no personal data collected, your legal and compliance teams take on less risk.
Built-in accessibility compliance
WCAG 2.1 AAA, EAA, Section 508, and EN 301 549 compliant out of the box.
Full keyboard navigation, an audio alternative, and a colorblind-safe design help you meet accessibility mandates across major markets.
Invisible bot protection
MTCaptcha provides invisible bot protection that verifies visitors quietly in the background, with no checkboxes or puzzles.
Your most valuable conversion flows stay protected and friction-free.
Adaptive risk scoring
Every request returns a real-time risk score from 0.0 to 1.0.
Your backend can then trigger MFA, rate-limit, or block suspicious traffic while trusted users pass straight through.
Flexible SDKs and integration
MTCaptcha fits into your existing stack without custom middleware.
SDKs for React, Vue, React Native, Java, Node.js, and PHP plug in at the application layer, while server-side verification keeps your backend in control of every decision.
Edge-based DDoS protection
Malicious requests and sudden surges are stopped at the edge, before they ever reach your servers.
Auto-scaling keeps your services available and your infrastructure costs steady, even when something goes wrong.
Global availability
MTCaptcha runs on a global edge network, so verification stays quick no matter where your visitors are.
That includes mainland China and other restricted networks, where many traditional CAPTCHA services struggle to load.
Fully customizable styling
Choose from eleven preset themes, or fine-tune style and color through the JavaScript initialization config so the widget matches your brand.
You can preview your changes in the Code Builder's Custom Style tab before adding them to your site.
