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

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.

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.

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 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.

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")

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

ngrok http 80
