Security Considerations

While ngrok.app is an established platform, these capabilities require extra vigilance.

User-Generated Content

ngrok.app hosts content created by its users, not the platform operator. Individual posts, profiles, or pages may contain scams, misinformation, or phishing attempts that the platform hasn't yet detected or removed.

Custom Subdomains

ngrok.app allows users to create custom addresses like "anything.ngrok.app". An address like "paypal-secure.ngrok.app" may look official but is actually controlled by whoever registered that subdomain—not ngrok, Inc..

Remember: The platform itself is established, but even established platforms can be abused.
