I did, might still go that route, but Redimo isn’t a web server (although I am building one that I’m planning to license under Mongo’s SSPL). The code is a Go / Ruby / JS library that builds with your code, so think the GPL does apply. As far as I know the LGPL doesn’t trigger if no modifications are made to the library itself.

Wanted to choose only well known licenses, but I am looking at other options. LicenseZero works only for individuals, by the way - companies will have to go through a separate process, or ask all their employees to buy separately.
