Open Source Alternatives to Visual Studio Code
Advertisement
Visual Studio Code is Microsoft's proprietary code editor, built on top of the MIT-licensed 'Code - OSS' project but distributed under a closed license with added telemetry, branding, and a proprietary extension marketplace. Full details →
Visual Studio Code’s official build adds Microsoft telemetry and a marketplace license restricted to Microsoft’s own binaries on top of an otherwise MIT-licensed codebase, so there’s a real gap between what’s open source and what most people actually install. VSCodium closes that gap directly, building the identical source without any of the added telemetry or licensing restrictions — it’s the closest thing to a drop-in replacement available. Neovim and Zed offer genuinely different editing paradigms instead of a like-for-like swap: Neovim’s terminal-based, modal editing suits keyboard-driven and remote workflows, while Zed’s GPU-accelerated interface and built-in collaboration target raw performance and pair programming. Pulsar rounds out the options as a continuation of GitHub’s discontinued Atom editor, aimed at anyone who was still using Atom when Microsoft ended its development.

Open Source Alternatives
VSCodium
Community builds of VS Code without Microsoft branding or telemetry
VSCodium provides free, community-built binaries of Microsoft's open source 'Code - OSS' project, with telemetry disabled and Microsoft's branding and licensing removed.
Neovim
Open source, extensible terminal-based text editor and IDE
Neovim is a free, open source refactor of Vim, focused on extensibility and modern plugin architecture while keeping Vim's modal editing model and terminal-based interface.
Zed
Open source, GPU-accelerated code editor built in Rust
Zed is a free, open source code editor built in Rust by former Atom and Tree-sitter developers, designed for high performance and built-in real-time collaboration.
Pulsar
Community-maintained continuation of GitHub's discontinued Atom editor
Pulsar is a free, open source code editor that continues development of GitHub's Atom editor after Microsoft discontinued it in December 2022, preserving Atom's interface and package ecosystem.
Feature Comparison
| Feature | Platforms | Interface | Extension Ecosystem | Best For |
|---|---|---|---|---|
| VSCodium | Linux, Windows, macOS | Identical to VS Code | Open VSX Registry | A direct, drop-in VS Code replacement |
| Neovim | Linux, Windows, macOS | Terminal-based, modal editing | Lua plugin ecosystem | Keyboard-driven and remote/SSH development |
| Zed | Linux, macOS | GPU-accelerated GUI | Growing native extension API | Performance-focused and real-time collaboration |
| Pulsar | Linux, Windows, macOS | GUI, Atom-style | Existing Atom package library | Former Atom users wanting continued updates |
Frequently Asked Questions
Is Visual Studio Code actually open source?
Partially. Microsoft publishes the underlying 'Code - OSS' source under the MIT license, but the official Visual Studio Code product you download from Microsoft is a separate, proprietary build with added telemetry and a marketplace license restricted to Microsoft's own binaries. VSCodium builds the same MIT-licensed source without any of that.
What's the closest free alternative to VS Code?
VSCodium is the closest match by far — it's built from the exact same source code as VS Code, so the interface, shortcuts, and core features are identical. The main trade-off is using the community-run Open VSX Registry instead of Microsoft's marketplace for extensions.
Do these alternatives support VS Code extensions?
VSCodium supports most VS Code extensions through Open VSX, though a small number of Microsoft-published extensions are marketplace-restricted and unavailable. Neovim, Zed, and Pulsar each have their own separate plugin ecosystems and are not directly compatible with VS Code extensions.
