`zrok` is a next-generation, peer-to-peer sharing platform built on top of [OpenZiti](https://docs.openziti.io/docs/learn/introduction/), a programmable zero-trust network overlay. `zrok` is a _Ziti Native Application_.



`zrok` facilitates sharing resources both publicly and privately. Public sharing allows you to share `zrok` resources with non-`zrok` users over the public internet. Private sharing allows you to directly share your resources peer-to-peer with other `zrok` users without changing your security or firewall settings.



Like other offerings in this space, `zrok` allows users to share tunnels for HTTP, TCP and UDP network resources. `zrok` additionally allows users to easily and rapidly share files, web content, and custom resources in a peer-to-peer manner.



`zrok` is an extensible platform for sharing. Initially we're targeting technical users. Super-simple sharing for end users is planned and in the backlog.

## Frictionless



You can be up and sharing using the `zrok.io` service in minutes. Here is a synopsis of what's involved:



* Download the binary for your platform [here](https://github.com/openziti/zrok/releases/latest)

* `zrok invite` to create an account with the service

* `zrok enable` to enable your shell environment for sharing with the service



### And then... sharing...



Easily share private network resources with public internet users, securely, without having to alter any of your local network configuration:



```

$ zrok share public localhost:8080

```



![zrok share public](docs/images/zrok_share_public.png)



```

$ curl -s https://dslno640nct4.share.zrok.io | head



    

    

    

    

    

```



Share "network drives" with public and private users running on Windows, macOS, or Linux systems:



```

$ zrok share public --backend-mode drive ~/Repos/zrok

```



![zrok share public -b drive](docs/images/zrok_share_public_drive.png)



Mounting and working with shared drives is simple, and works with any applications on the end users' systems:

See the [Concepts and Getting Started Guide](https://docs.zrok.io/docs/getting-started) for a full overview.



## The `zrok` SDK



`zrok` includes an SDK that allows you to embed `zrok` sharing capabilities into your own applications. If you're familiar with a golang `net.Conn` and `net.Listener`, you'll be right at home with our SDK.



### A Simple `zrok` Sharing Service



```go

// load enabled zrok environment

root, err := environment.LoadRoot()



// request a share for your resource

shr, err := sdk.CreateShare(root, &sdk.ShareRequest{

    BackendMode: sdk.TcpTunnelBackendMode,

    ShareMode:   sdk.PrivateShareMode,

	// ...

})



// accept requests for your resource

listener, err := sdk.NewListener(shr.Token, root)

```



### A Simple `zrok` Client



```go

// load enabled zrok environment

root, err := environment.LoadRoot()



// request access to a shared zrok resource

acc, err := sdk.CreateAccess(root, &sdk.AccessRequest{ShareToken: shrToken})



// establish a connection to the resource directly

conn, err := sdk.NewDialer(shrToken, root)

```



This [blog post](https://blog.openziti.io/the-zrok-sdk) provides more details for [getting started](https://blog.openziti.io/the-zrok-sdk) with the `zrok` SDK.



## Self-Hosting



`zrok` is designed to scale up to support extremely large service instances. `zrok.io` is a public service instance operated by NetFoundry using the same code base that is available to self-hosted environments.



`zrok` is also designed to scale down to support extremely small deployments. Run `zrok` and OpenZiti on a Raspberry Pi!



The single `zrok` binary contains everything you need to operate `zrok` environments and also host your own service instances. Just add an OpenZiti network and you're up and running.



See the [Self-Hosting Guide](https://docs.zrok.io/docs/guides/self-hosting/self_hosting_guide/) for details on getting your own `zrok` service instance running.



## zrok Office Hours



We maintain a growing playlist of videos focusing on various aspects of `zrok`. This includes the "office hours" series, which are longer-format videos digging into the implementation of `zrok` and showcasing some of the latest features and capabilities:

## Building



If you are interested in building `zrok` for yourself instead of using a released package, please refer to [BUILD.md](./BUILD.md)
