Choosing Vscodium for a Telemetry‑Free VS Code Experience with Open VSX

Problem: VS Code’s telemetry and marketplace dependence

Many developers appreciate VS Code’s rich extension ecosystem but are uncomfortable with the built‑in telemetry that sends usage data to Microsoft. At the same time, the default extension marketplace requires a Microsoft account and ties you to the Microsoft‑hosted gallery. If you want a fully open‑source build that removes tracking and uses a community‑driven registry, Vscodium offers a practical alternative.

What Vscodium changes

Vscodium is produced by taking the upstream VS Code source, stripping out all Microsoft‑specific telemetry, tracking, and licensing code, and then rebuilding the binaries. The resulting distribution:

• Is functionally identical to the corresponding VS Code release, minus the proprietary components.
• Uses the Open VSX registry as the default extension marketplace, so extensions are fetched from https://open-vsx.org without requiring a Microsoft account.
• Publishes SHA256 checksums and signed artifacts for each release, enabling integrity verification.

Verifying the build

Before running any binary, you should confirm that the download matches the published checksum. This step protects against tampered downloads.

# Replace VERSION with the release you want, e.g., 1.96.2
VERSION=1.96.2
PLATFORM=linux-x64
wget https://github.com/VSCodium/vscodium/releases/download/${VERSION}/Vscodium-${PLATFORM}-${VERSION}.tar.gz
wget https://github.com/VSCodium/vscodium/releases/download/${VERSION}/Vscodium-${PLATFORM}-${VERSION}.tar.gz.sha256sum
sha256sum -c Vscodium-${PLATFORM}-${VERSION}.tar.gz.sha256sum

If the command outputs “OK”, the file is intact. You can also check that telemetry is disabled by running the binary and looking for an empty telemetry ID:

./Vscodium-${PLATFORM}-${VERSION}/bin/code --version
# Example output: 1.96.2
# The telemetry ID field is omitted or empty.

Worked example: installing an extension from Open VSX

Once you have verified the binary, you can install extensions just as you would with VS Code. The difference is that the source URL shown in the Extensions view points to Open VSX.

# Assuming the extracted binary is in the current directory
./Vscodium-${PLATFORM}-${VERSION}/bin/code --install-extension ms-python.python

After installation, open the Extensions view (Ctrl+Shift+X), locate the Python extension, click the gear icon, and note the “Source” field. It should read something like https://open-vsx.org/publisher/ms-python/name/python, confirming that the extension came from the Open VSX registry.

Trade‑offs and limitations

• Microsoft‑dependent extensions: Features such as Live Share, Remote Containers, or certain Azure integrations rely on Microsoft services and may not function fully without additional configuration or may be unavailable.
• Release lag: Vscodium builds are produced after the official VS Code release, so you might see a delay of a few days before the latest bug fixes or language‑server updates appear.

Actionable closing

If telemetry‑free operation and a community‑driven extension marketplace align with your workflow, adopt Vscodium by:

1. Downloading the latest release from the GitHub releases page.
2. Verifying the SHA256 checksum as shown above.
3. Running the binary and confirming the absence of a telemetry ID.
4. Installing your usual extensions and checking that their source URLs point to open-vsx.org.

Periodically repeat the verification step when updating to a new release, and keep an eye on the Open VSX registry for any extensions you rely on that may have delayed availability.
