The core program is exactly the same, built from the same source code, using the same build script, just with different default settings and configs (mainly turning off all telemetry and changing the branding). The big difference is when it comes to extensions. VSCodium does not have access to the official Microsoft extension marketplace or any of the closed source Microsoft extensions. Most Open Source and third party extensions are available, but a few will be missing, with the biggest one probably being the Remote Development tools.
