Shipping ready-to-run Python apps without the need to install Python

30 minutes


Have you ever wanted to ship a script or application to a friend or client, without requiring a specific Python installation or providing complex installation instructions ? Or you want to squeeze out that last bit of juice from your Docker Python image to speed up deployment. Then eGenix PyRun is for you.

PyRun is an open source, Apache-licensed, compressed, single file Python compatible run-time, which fits into merely 5 MB on disk.

It can be used to ship pure Python products as a single file on Unix platforms, create Python Docker images with very small footprint to speed up deployment, or as a neat venv replacement, truly isolating applications from any OS or other Python installations, giving you a predictable target for Python applications across Unix platforms.

We have been using PyRun internally at eGenix for many years and open sourced it back in 2012. This year, we are moving the project to Github and relaunching it, in order to present it to the wider open source and Python community.

The talk will go into details on how PyRun is built from the Python source tree, how to create your own single file Python apps, where it can be put to good use, the roadmap we have for PyRun and what its limitations are.
