Vscode is like Chrome

And

VS Codium is like Chromium

It has Microsoft BLObs baked in as part of the build process. VS Codium is the FLOSS distribution of VS code’s open source code. Liveshare doesn’t appear in the package repo Codium uses (because of the Microsoft BLObs it contains as an extension). For work I manually download the live share extension VSX and load it into vscodium
