pyngrok

pyngrok is a Python wrapper for ngrok that manages its own binary, making ngrok available via a convenient Python API.

ngrok is a reverse proxy that opens secure tunnels from public URLs to localhost. It's perfect for rapid development (test webhooks, demo local websites, enable SSH access), establishing ingress to external networks and devices, building production APIs (traffic policies, OAuth, load balancing), and more. And it's made even more powerful with native Python integration through the pyngrok client.

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 our 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",
                                  domain="some-endpoint.internal",
                                  pooling_enabled=True)

The connect method takes kwargs as well, which allows us 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.

ngrok's API

The api method allows us to use the local ngrok agent to make requests against the ngrok API, if we have set an API key. For example, here we 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")

ngrok's Edges

ngrok has deprecated Edges and will sunset Labeled Tunnels on December 31st, 2025. See this issue for more details.

To use ngrok's Edges with pyngrok, first configure an Edge on ngrok's dashboard (with at least one Endpoint mapped to the Edge), and define a labeled tunnel in the ngrok config file that points to the Edge.

tunnels:
  some-edge-tunnel:
    labels:
      - edge=my_edge_id
    addr: http://localhost:80

To start a labeled tunnel in pyngrok, pass its name to connect.

from pyngrok import ngrok

# Open the Edge tunnel that is defined in the config file
named_tunnel = ngrok.connect(name="some-edge-tunnel")

Once an Edge tunnel is started, it can be managed through ngrok's dashboard.

Command Line Usage

This package puts the default ngrok binary on our 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.
