Block fake signups before they reach your database

Fake signups can distort your analytics, drain your resources, and exploit your free plans.

Checker helps you stop them before they ever touch your backend.

It works by instantly identifying disposable emails and suspicious domains at the point of signup.

With over 170,000 known temporary email domains and sub-200ms response times, it’s designed for speed and scale.

You can integrate Checker via API or use the WordPress plugin for no-code protection.

A real-time dashboard shows you blocked signups, domain activity, and threat trends.

It also protects your freemium model by stopping users who try to create multiple trial accounts.

Coming soon, it will detect risky IPs and device/browser fingerprint abuse to block more advanced fraud.

For SaaS products, membership platforms, and lead-gen sites, it helps keep your user data clean from day one.

You get better data, lower infrastructure costs, and fewer support headaches — all with a lightweight setup.
