Segment 1 (Deep Dive)

Code-OSS / Visual Studio Code / VSCodium

Code-OSS is the open-source foundation upon which Microsoft’s Visual Studio Code is built. It is a distribution of the Code - OSS repository, which is developed by Microsoft in collaboration with the community under the MIT license. Code-OSS provides comprehensive code editing, navigation, debugging, extensibility, and integration with existing tools, forming the core of the edit-build-debug cycle for developers.

Microsoft’s Visual Studio Code is a proprietary distribution of the same source code with additional Microsoft-specific customizations. These customizations include Microsoft trademarks, branding (such as the product name “Microsoft Visual Studio Code”), integration with the Visual Studio Marketplace, remote development features, telemetry collection, and access to proprietary extensions like the C#/.NET debugger. The proprietary components are enforced through mechanisms such as a handshake protocol to ensure compliance with licensing restrictions.

VSCodium is a community-driven project that actively disables telemetry by default and rewrites telemetry-related code to prevent any data from being sent to Microsoft servers, ensuring a more privacy-focused experience. VSCodium also uses the Open VSX Registry as its default extension marketplace, which is open-source and vendor-neutral, allowing extensions to be published and used without requiring a Microsoft account or agreeing to Microsoft’s terms of service.
