    Infinitely transfer between every device over HTTP/HTTPS
    Piping Server hello


    Piping Server is simple. You can transfer as follows.

    # Send
    echo 'hello, world' | curl -T - https://ppng.io/hello
    # Get
    curl https://ppng.io/hello > hello.txt

    Piping Server transfers data to POST /hello or PUT /hello into GET /hello. The path /hello can be anything such as /mypath or /mypath/123/. A sender and receivers who specify the same path can transfer. Both the sender and the recipient can start the transfer first. The first one waits for the other.

    You can also use Web UI like https://ppng.io on your browser. A more modern UI is found in https://piping-ui.org, which supports E2E encryption.


    The most important thing is that the data are streamed. This means that you can transfer any data infinitely. The demo below transfers an infinite text stream with seq inf.

    Piping Server is designed based on the ideas as follows.

    • Infinite transfer: You can transfer any kind of data infinitely on a stream. Streams are very efficient in terms of both time and space.
    • Zero installation: All you need is to have either a Web browser or curl, which are widely pre-installed. You do not need to install any extra software.
    • Simpleness: Making simple makes it more secure.
    • Storageless: The server makes transfer more secure since the server never stores your data.
    • Purity: The server streams over pure HTTP, which makes integration easier with other softwares.
    • Engineer friendly: Also designed for Unix/Linux users, who use pipes, not only for Web browser users.


    Any data such as text streams, video streams and protocols can be streamed over Piping Server. Here are applications that fully use the power of pure HTTP.
    See: "The Power of Pure HTTP – screen share, real-time messaging, SSH and VNC"

    The most important thing is that Piping Server stays simple. The applications use Piping Server as a core of data communication. It transfers data to POST /thepath into GET /thepath streamingly. The stream makes real-time communications over every device possible.

    See "Ecosystem around Piping Server · nwtgck/piping-server Wiki" to find more about softwares using Piping Server.

    Power of HTTP

    In my experiment, Piping Server transferred 1,110TB (≈ 1PB) in a single HTTP request for 64 days and 2 hours at least. This means that it can transfer huge data and keep a request for about 2 months.

    Engineer-friendly help

    Get help and version only with curl.

    curl https://ppng.io/help
    curl https://ppng.io/version

    Transfer to multiple receivers

    You can transfer to multiple receivers. In the demo below, query parameter ?n=3 is specified to allow three receivers.

    Public servers

    Here are public Piping Servers.

    Self-host on Docker

    Run a Piping Server on http://localhost:8080 as follows.

    docker run -p 8080:8080 nwtgck/piping-server

    Run a server in background and it automatically always restarts.

    docker run -p 8080:8080 -d --restart=always nwtgck/piping-server

    Self-host on free services

    Here are easier ways to own your Piping Server.

    See "Ecosystem around Piping Server · nwtgck/piping-server Wiki" to find more about self-hosting.

    Command-line options

    Here is available CLI options by piping-server --help.

      --help          Show help                                            [boolean]
      --version       Show version number                                  [boolean]
      --http-port     Port of HTTP server                            [default: 8080]
      --enable-https  Enable HTTPS                                  [default: false]
      --https-port    Port of HTTPS server                                  [number]
      --key-path      Private key path                                      [string]
      --crt-path      Certification path                                    [string]
