Gatekeepr

Gatekeepr protects your platform from abuse by validating user signals before they take action. It checks email, domain, IP, and user agent against multiple criteria, including disposable addresses, domain age, blocklists, Tor usage, and automation.

Gatekeepr targets developers, SaaS founders, and platform owners who want to protect their apps from fake sign-ups, spam, and automated abuse. It's built for anyone who handles user-generated actions like registrations, form submissions, or comments.
