pyngrok – a Python wrapper for ngrok

pyngrok is a Python wrapper for ngrok that manages its own binary and puts it on your path, making ngrok readily available from anywhere on the command line and 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.

Basic Usage

To open a tunnel, use the connect method, which returns the public URL generated by ngrok.

from pyngrok import ngrok

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

# Open a SSH tunnel
# <NgrokTunnel: "tcp://" -> "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 properties that are supported by ngrok.

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.

ngrok Version Compatibility

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

from pyngrok import conf

conf.get_default().ngrok_version = "v2"

Python 2.7

The last version of pyngrok that supports Python 2.7 is 4.1.x, so we need to pin pyngrok>=4.1,<4.2 if we still want to use pyngrok with this version of Python. Its legacy documentation can be found here.
