You can buy an installer or dedicated portable USB. These are one time purchases that can save you time. Doing your own install is still free.
===============================================
This video is part of a series that shows you how to use free and open source software to do drone mapping and 3D scanning. In this video we will install Docker so you can run WebODM
which is the browser based GUI for OpenDroneMap. See the other videos in this series to learn how to use OpenDroneMap to process your images into textured mesh, GEOTiff and other formats.
Also to convert your 3D model to HTML format that can be used on a website or viewed with a browser.
