Heroku makes deployment of arbitrary apps including Panel apps and dashboards very easy and provides a free tier to get you started. This makes it a great starting point for users not too familiar with web development and deployment.

To get started working with Heroku signup for a free account and download and install the CLI. Once you are set up follow the instructions to log into the CLI.

  1. Create a new Git repo (or to follow along clone the minimal-heroku-demo GitHub repo)

  2. Add a Jupyter notebook or Python script which declares a Panel app or dashboard to the repository.

  3. Define a requirements.txt containing all the requirements for your app (including Panel itself). For the sample app the requirements are as minimal as:

  1. Define a Procfile which declares the command Heroku should run to serve the app. In the sample app the following command serves the iris_kmeans.ipynb example. The websocket origin should match the name of the app on Heroku which you will declare in the next step:

web: panel serve --address="" --port=$PORT iris_kmeans.ipynb
  1. Create a Heroku app using the CLI ensuring that the name matches the URL we declared in the previous step:

heroku create app-name
  1. Push the app to heroku and wait until it is deployed.

  2. Visit the app at

Once you have deployed the app you might find that if your app is visited by more than one user at a time it will become unresponsive. In this case you can use the Heroku CLI to scale your deployment.
