Launch Engineering for Desktop Software built using Python & Qt.

You've got something working. A Python application that works in your lab or on your machine. It solves a real problem and is ready to be used by other users. But going from a prototype to a product is a big step.

Now, you need to think about:

  • Packaging & distribution, cross-platform macOS, Windows & Linux
  • Installer design and testing, validation
  • Security management, certificates and passing Virus Scanner checks
  • UI polish that makes your users want to use your app
  • Functional update mechanism
  • Error tracking & diagnosis

That's a lot to learn just to get your software out there.

With Launch Window I provide custom launch engineering services, specifically tailored for teams looking to take their Python applications from the lab workbench to market.

I'll save you time & headaches, and let you keep focus on the things you're good at.
