It’s an add-on to Zwift that lets you create your own custom routes and not be limited to the fixed ones offered by Zwift.

I’ve been working on this for a little over a year and I’ve had some good reactions from folks using it.

Even so, apart from one person sponsoring me on GitHub with a one-off that’s it money wise. I’ve been toying with the idea of a paid version but no clue if that’s even worthwhile to do.
