NGrok

ngrok provides a secure ingress platform that creates encrypted tunnels from public endpoints to local or private services without requiring changes to firewall rules or DNS configuration. Developers use it to expose localhost applications, APIs, and webhooks to the internet for testing, demos, and staging environments. The platform issues public URLs instantly, enabling quick sharing of work-in-progress applications with teammates, clients, or third-party services. Beyond individual developer use, ngrok offers an API gateway and Kubernetes-native networking layer that businesses use to manage traffic, enforce authentication, and apply security policies across distributed services. Its core capabilities include TLS termination, custom domains, load balancing, and observability tools that give engineering teams visibility into traffic flowing through their tunnels.
