More open source, browser-accessible tools is a good thing.

That said, aren't Prusa/Orca/etc. all already open-source (and part of the same lineage)?

no shared lineage. Cura and Kiri started around the same time (2011/2012), but as completely separate projects. Cura is a C++ desktop app and Kiri has always been 100% browser-based (no cloud, all computation in the browser sandbox). the licenses are different, too. Cura/Prusa/Orca are GPL based and Kiri is MIT.

I'm not talking about Kiri; I'm talking about the mainstream derivatives of Slic3r.

		Yes, Slic3r -> Prusa Slicer -> Bambu Studio -> Orca Slicer. Many "official" slicers (Elegoo, Creality, Anycubic, and I imagine others) derive from Orca.
