Hey!
I created an open source Outer Wilds modding tool which allows for the creation and manipulation of planets and stars either through JSON or with an API. We have a main repo, examples project, template, GUI editor, and more on our organization: New Horizons.
I help run the infrastructure for outerwildsmods.com, such as the mod manager, database, and more.
I also created a mod manager and database for distributing DREDGE mods including my own multiplayer mod, Cosmic Horror Fishing Buddies, and DREDGE VR. Find out more on dredgemods.com
