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
