## What it is
zrok is an open-source tool for securely sharing local web services, files, and TCP/UDP resources over the internet without firewall or NAT changes, built on the OpenZiti zero-trust network overlay. It is available as a free hosted service or fully self-hostable, and includes a Go SDK for embedding sharing into applications.

## Use cases
- expose a localhost web app to the internet securely
- share a folder as a network drive without a server
- share TCP/UDP services privately with teammates
- tunnel through firewalls and NAT without port forwarding
- self-host a secure tunneling service
- embed secure resource sharing into a Go application

## When to choose
- you need ngrok-like public or private sharing with zero-trust encryption
- you cannot change firewall or NAT configuration
- you want to self-host the entire sharing infrastructure
- you need to share files or non-HTTP services, not just web endpoints

## When to avoid
- you only need a simple static file host without tunneling
- you require a mature GUI-based product rather than a CLI
- your traffic must not traverse any third-party relay and you cannot self-host
