What is ngrok?
ngrok is a developer infrastructure tool that routes and secures network traffic to applications, APIs, and AI models. It is used by developers to connect their services, whether they are running locally during development or deployed in a production environment. This tool helps manage how external traffic reaches internal services. Developers use ngrok to share local applications, test webhooks, and connect local servers. They can route traffic to self-hosted models, run preview workloads, and deliver secure APIs. It also allows them to receive webhooks on-premises, connect privately across networks, and open SSH and RDP sessions.
