base on Secure internet sharing made simple. # zrok - Secure internet sharing made simple  **Share anything, anywhere, instantly. Enterprise reliability. No firewall changes. No port forwarding. No hassle.** zrok lets you securely share web services, files, and network resources with anyone—whether they're across the internet or your private network. Built on zero-trust networking, it works through firewalls and NAT without requiring any network configuration changes. ## Quick start Get sharing in under 2 minutes: 1. **[Install zrok](https://docs.zrok.io/docs/guides/install/)** for your platform 2. **Get an account**: `zrok invite` (use the free [zrok.io service](https://docs.zrok.io/docs/getting-started/)) 3. **Enable sharing**: `zrok enable` That's it! Now you can share anything: ```bash # Share a web service publicly $ zrok share public localhost:8080 # Share files as a network drive $ zrok share public --backend-mode drive ~/Documents # Share privately with other zrok users $ zrok share private localhost:3000 ```  ## What you can share ### Web services Instantly make local web apps accessible over the internet: ```bash zrok share public localhost:8080 ```  ### Files & directories Turn any folder into a shareable network drive: ```bash zrok share public --backend-mode drive ~/Repos/zrok ```   ### Private resources Share TCP/UDP services securely with other zrok users—no public internet exposure. ## Key features - **Zero Configuration**: Works through firewalls, NAT, and corporate networks - **Secure by Default**: End-to-end encryption with zero-trust architecture - **Public & Private Sharing**: Share with anyone or just specific users - **Multiple Protocols**: HTTP/HTTPS, TCP, UDP, and file sharing - **Cross-Platform**: Windows, macOS, Linux, and Raspberry Pi - **Self-Hostable**: Run your own zrok service instance ## How it works zrok is built on [OpenZiti](https://docs.openziti.io/docs/learn/introduction/), a programmable zero-trust network overlay. This means: - **No inbound connectivity required**: Works from behind firewalls and NAT - **End-to-end encryption**: All traffic is encrypted, even from zrok servers - **Peer-to-peer connections**: Direct connections between users when possible - **Identity-based access**: Share with specific users, not IP addresses ## Developer SDK Embed zrok sharing into your applications with our Go SDK: ```go // Create a share shr, err := sdk.CreateShare(root, &sdk.ShareRequest{ BackendMode: sdk.TcpTunnelBackendMode, ShareMode: sdk.PrivateShareMode, }) // Accept connections listener, err := sdk.NewListener(shr.Token, root) ``` [Read the SDK guide](https://blog.openziti.io/the-zrok-sdk) for complete examples. ## Self-hosting Run your own zrok service—from Raspberry Pi to enterprise scale: - Single binary contains everything you need - Scales from small personal instances to large public services - Built on the same codebase as the public zrok.io service [Self-Hosting Guide](https://docs.zrok.io/docs/guides/self-hosting/self_hosting_guide/) ## Resources - **[Documentation](https://docs.zrok.io/)** - **[Office Hours Videos](https://www.youtube.com/watch?v=Edqv7yRmXb0&list=PLMUj_5fklasLuM6XiCNqwAFBuZD1t2lO2)** - **[Building from source](./BUILD.md)** - **[Contributing](./CONTRIBUTING.md)** --- *Ready to start sharing?
