Top Open‑Source Alternatives to VS Code You Can Use Today

VSCodium

URL: https://vscodium.com

VSCodium distributes the compiled Code‑OSS binaries built from the VS Code source without Microsoft‑proprietary add‑ons. Telemetry is disabled by default, providing a VS Code‑compatible experience while omitting Microsoft‑only components such as the C# debugger. Those components can be added manually if required.

Code‑OSS (self‑compiled)

URL: https://github.com/flathub/com.visualstudio.code.oss

Compiling VS Code from source produces an executable named Code‑OSS. The binary follows the same license as VSCodium and runs identically to the official build. When building from source, verify that telemetry is disabled on first launch.
