pyngrok

pyngrok gives Python the complete ngrok agent, with programmatic tunnels for ingress, inspection, webhooks, demos, and APIs. ngrok is a reverse proxy that opens secure tunnels from public URLs to localhost, and because pyngrok runs the real agent, you get everything it offers, from traffic policies and OAuth to its web inspector and request replay, all callable from Python.

Installation

pyngrok is available on PyPI and can be installed using pip:

pip install pyngrok

or conda:

conda install -c conda-forge pyngrok

That's it! pyngrok is now available as a package to your Python projects, and ngrok is now available from the command line.

Basic Usage

Open a Tunnel

To open a tunnel, use the connect method, which returns a NgrokTunnel, and this returned object has a reference to the public URL generated by ngrok in its public_url attribute.

from pyngrok import ngrok

# Open a HTTP tunnel on the default port 80
# <NgrokTunnel: "https://<public_sub>.ngrok.io" -> "http://localhost:80">
http_tunnel = ngrok.connect()

# Open a SSH tunnel
# <NgrokTunnel: "tcp://0.tcp.ngrok.io:12345" -> "localhost:22">
ssh_tunnel = ngrok.connect("22", "tcp")

# Open a named tunnel from the config file
named_tunnel = ngrok.connect(name="my-config-file-tunnel")

# Open an Internal Endpoint that's load balanced
# <NgrokTunnel: "https://some-endpoint.internal" -> "http://localhost:9000">
internal_endpoint = ngrok.connect(addr="9000",
                                  url="https://some-endpoint.internal",
                                  pooling_enabled=True)

The connect method takes kwargs as well, which allows you to pass additional tunnel configurations that are supported by ngrok (or the name of a tunnel defined in ngrok's config file), as documented here.

Note: pyngrok unifies ngrok's "tunnel" (v2) and "endpoint" (v3) concepts behind a single API: connect() returns an NgrokTunnel and handles the differences for you through the config_version you set. All ngrok features are available to you through this. For v3-specific Endpoints, see Using v3 Endpoints.

ngrok's API

The api method allows you to use the local ngrok agent to make requests against the ngrok API, if you have set an API key. For example, here's how you would reserve a ngrok domain, then create a Cloud Endpoint with an associated traffic policy:

from pyngrok import ngrok

domain = "some-domain.ngrok.dev"
ngrok.api("reserved-domains", "create",
          "--domain", domain)
ngrok.api("endpoints", "create",
          "--bindings", "public",
          "--url", f"https://{domain}",
          "--traffic-policy-file", "policy.yml")

Command Line Usage

This package puts the default ngrok binary on your path, so all features of ngrok are available on the command line.

ngrok http 80

For details on how to fully leverage ngrok from the command line, see ngrok's official documentation.
