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 tool that opens secure tunnels from public URLs to localhost, perfect for exposing local web servers, building webhook integrations, enabling SSH access, testing chatbots, demoing from your own machine, and more, and its made even more powerful with native Python integration through pyngrok.

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.

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(3)

# 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_tunnel_name")

The connect method takes kwargs as well, which allows us to pass additional tunnel configurations that are supported by ngrok, as documented here.

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 defind 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.

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

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

For more advanced usage, pyngrok's official documentation is available at http://pyngrok.readthedocs.io.

pyngrok is compatible with ngrok v2 and v3, but by default it will install v3. To install v2 instead, set ngrok_version to "v2" in PyngrokConfig.
