In plain words
ngrok is developer infrastructure that creates secure tunnels routing traffic to applications, APIs, and AI models regardless of where they run. It allows developers to start applications locally and route them to production environments by changing a single URL. The platform includes built-in failover and observability features, supporting both hosted and self-hosted deployments. It functions as a cloud networking platform that secures, transforms, and routes traffic across distributed services.

This means you can expose your services without opening a public port. Pico runs as a cluster of nodes in order to be fault tolerant, scale horizontally and support zero downtime deployments. It is also easy to host, such as a…
