Vscodium

TL;DR

• What it is: Pre-built binaries of Microsoft’s VS Code source code, compiled without telemetry, proprietary licensing, or Microsoft branding. Same editor, different build. MIT-licensed.
• Who it’s for: Developers who want the VS Code experience without sending usage data to Microsoft. Privacy-conscious users, open-source advocates, and anyone on a Linux distribution that prefers fully FOSS packages.
• Cost angle: Both VS Code and VSCodium are free. This isn’t about saving money — it’s about what you give up (telemetry data, extension marketplace access) and what you gain (verified privacy, MIT license).
• Key strength: Functionally identical to VS Code. Same interface, same performance, same underlying code. If you can use VS Code, you can use VSCodium. The switch takes minutes.
• Key weakness: Cannot access Microsoft’s Visual Studio Marketplace. Uses Open VSX Registry instead, which has ~5,000 extensions versus Microsoft’s 40,000+. Key missing extensions: Remote Development pack, GitHub Copilot, Live Share.

What is VSCodium

VSCodium is not a fork of VS Code. The project’s README states it plainly: “This is not a fork. This is a repository of scripts to automatically build Microsoft’s vscode repository into freely-licensed binaries with a community-driven default configuration.”

Microsoft’s VS Code has an interesting licensing split. The source code in the microsoft/vscode GitHub repository is MIT-licensed — genuinely open source. But the binaries you download from code.visualstudio.com are compiled with a different product.json that adds Microsoft telemetry endpoints, proprietary marketplace access, and a non-FOSS license. As a VS Code maintainer explained: “When we build Visual Studio Code, we clone the vscode repository, we lay down a customized product.json that has Microsoft specific functionality (telemetry, gallery, logo, etc.)”

VSCodium takes the same MIT-licensed source code, builds it with a clean product.json that removes all Microsoft-specific endpoints, disables telemetry, and ships it under the MIT license. The result is functionally identical to VS Code — same editor, same performance, same extension host — minus the data collection.

The project has 30,539 GitHub stars. It ships for Windows, macOS, and Linux, available via Homebrew, WinGet, Chocolatey, Scoop, snap, Flatpak, and native package managers.

Why people choose it over VS Code, Cursor, and Zed

Versus VS Code. This is the only comparison that matters for most users. Functionally, VSCodium and VS Code are identical. The differences are:

1. Telemetry. VS Code sends usage data to Microsoft. You can “disable” it in settings, but you can’t verify that Microsoft fully complies — the binary is proprietary. VSCodium’s telemetry endpoints are removed at build time. Verifiable because the build scripts are open source.

2. License. VS Code’s download is under Microsoft’s proprietary license. VSCodium is MIT. For FOSS-committed Linux distributions and enterprises with strict licensing policies, this matters.

3. Extension marketplace. VS Code accesses the Visual Studio Marketplace (40,000+ extensions). VSCodium accesses the Open VSX Registry (~5,000 extensions). This is the practical cost of the switch.

Versus Cursor. Cursor is a VS Code fork focused on AI-assisted coding with native GPT-4 and Claude integration. It’s the opposite of VSCodium’s philosophy — Cursor adds more telemetry and proprietary features, not less. It costs $20/month for Pro. If AI coding assistance is your priority and privacy isn’t, Cursor is compelling. If privacy is your priority, Cursor is the wrong direction.

Versus Zed. Zed is a new editor written in Rust, claiming 2-10x faster performance than Electron-based editors. It’s open source (GPL v3) with native collaboration features and emerging AI integration. The extension ecosystem is nascent — nowhere near VS Code’s 40,000+. Zed is the forward-looking choice for developers willing to bet on a new ecosystem. VSCodium is the pragmatic choice for developers who want the mature VS Code ecosystem without Microsoft’s tracking.

What VSCodium removes vs keeps

What VSCodium removes:

• All telemetry endpoints (no data sent to Microsoft)
• Microsoft branding (logo, product name)
• Microsoft’s proprietary license (replaced with MIT)
• Visual Studio Marketplace access (replaced with Open VSX Registry)

What VSCodium keeps:

• Full editor functionality: syntax highlighting, IntelliSense, integrated terminal, Git integration, debugger, extension host
• All keyboard shortcuts and settings
• All themes and color schemes
• Extension API compatibility — any extension that works on Open VSX works identically
• Same update cadence — VSCodium tracks VS Code releases, typically shipping within days

What you lose (the marketplace gap):

• Remote Development pack — SSH, Containers, WSL development. Microsoft explicitly restricts it to VS Code. This is the most-requested missing feature.
• GitHub Copilot — requires Microsoft marketplace authentication. Alternatives: Codeium and TabNine work on Open VSX.
• Live Share — Microsoft-only real-time collaboration. Alternative: CodeTogether extension is available on Open VSX.
• ~35,000 other extensions that haven’t been published to Open VSX — though most popular extensions (Python, ESLint, Prettier, GitLens, Docker) are available.

Workarounds for the marketplace gap:

1. Download .vsix files from the VS Code marketplace website and install manually via codium --install-extension file.vsix.
2. Edit product.json to point to Microsoft’s marketplace URL (may violate Microsoft’s Terms of Service).
3. Use community tools that mirror specific extensions from the Microsoft marketplace to Open VSX.

Installation (2 minutes)

# macOS
brew install --cask vscodium

# Windows
winget install -e --id VSCodium.VSCodium

# Ubuntu/Debian — add repository, then:
sudo apt update && sudo apt install codium

# Arch Linux
yay -S vscodium-bin

Migrating from VS Code (5-15 minutes):

• Settings, keybindings, and snippets can be copied from ~/.config/Code/ to ~/.config/VSCodium/ (Linux) or equivalent paths on other OSes.
• Extensions installed from Open VSX will match most VS Code extensions.
• Settings Sync works but syncs to a different service (not Microsoft’s).

What can go sideways:

• macOS Gatekeeper. First launch on macOS Mojave+ may show “App can’t be opened because Apple cannot check it for malicious software.” Right-click and choose Open. One-time issue.
• Extension discovery. You search for an extension you use daily and it’s not on Open VSX. You need to check, install the .vsix manually, or find an alternative.
• Remote Development. If your workflow depends on SSH/Container/WSL development via VS Code’s Remote pack, switching to VSCodium breaks that workflow.

Who should use this

Use VSCodium if:

• You care about software privacy and want verified telemetry removal, not just a settings toggle.
• You’re on a FOSS-committed Linux distribution or organization with strict licensing requirements.
• Your development stack is web-focused (TypeScript, Python, Rust, Go) where Open VSX coverage is nearly complete.
• You don’t use Remote Development (SSH/Container/WSL) via VS Code’s extension pack.
• You’re comfortable installing occasional extensions manually from .vsix files.

Stay on VS Code if:

• You use Remote Development daily — there’s no VSCodium equivalent.
• GitHub Copilot is central to your workflow and alternatives don’t satisfy.
• You develop for .NET, Azure, or C++ where Microsoft-exclusive extensions are important.
• Telemetry doesn’t concern you and the convenience of the full marketplace matters more.

Use Cursor instead if:

• AI-assisted coding is your top priority and you don’t care about telemetry.
• You’re willing to pay $20/month for deeply integrated AI features.
