VSCodium Alternatives That Stay Open Source

VSCodium builds Microsoft's open source VS Code repository and ships the result as MIT-licensed binaries with telemetry turned off, per vscodium.com. It is alive and updated. The latest tag on GitHub, 1.143.17232 from October 28, 2026, moves to VS Code 1.143.1. Microsoft's official build reached 1.145 on November 4 and now ships weekly, so VSCodium usually sits a version or two behind.

The common reasons to look elsewhere come from the same extensions doc. VSCodium uses the Open VSX Registry, some Marketplace extensions are missing there, and Microsoft licenses Remote Development and its C# and C/C++ debuggers for the official build only. Other readers want an open source editor that is not built on Electron at all. The list below covers both groups.

Prices below are as of November 6, 2026. Our method is on How we review tools.

Quick comparison

Tool Best for Price Platforms

Zed

Zed drops Electron entirely. It is written in Rust on GPUI, a GPU-accelerated UI framework made by the same team, per zed.dev. The licence split is clear: InfoQ reports GPL for the editor, AGPL for server components and Apache 2 for GPUI, since the code opened in early 2024.

For a VSCodium user the appeal is a fast editor where AI is optional and works with your own keys. Vim mode and language server support are built in. VS Code extensions do not run, so you trade a big catalogue for speed.

Best for: VSCodium users who want an open source editor that feels faster and does not depend on Microsoft's codebase.

Pricing:

  • Personal: $0 forever, with your own API keys or external agents
  • Pro: $10 per month, unlimited edit predictions and $5 of tokens included
  • Business: $30 per seat per month

Watch out for:

  • Zed signs you in for hosted AI and collaboration. If you picked VSCodium to avoid accounts, keep to the local features.
  • It needs a DirectX 11 GPU on Windows and a Vulkan GPU on Linux, which rules out some older laptops and VMs.

Eclipse Theia IDE

Theia is the only pick here that runs the same extensions VSCodium does. The Theia site points users to more than 3,000 extensions on open-vsx.org, the same registry VSCodium uses. The code is separate from Microsoft's, though, and the project sits at the Eclipse Foundation with vendor-neutral governance.

The latest release is 1.76, with a Community Release dated 2026-08. Downloads cover Windows, Linux as AppImage or Snap, and macOS on Intel and ARM, plus an online trial. Its AI features take any model, cloud, self-hosted or local, and the site says it sends no telemetry on your code, prompts or AI usage.

Best for: Teams that want VS Code-style extensions in an editor governed by a foundation rather than a single vendor.

Pricing:

  • Free and open source

Watch out for:

  • The download section warns that the Mac x86 build may run slowly and unstably on recent ARM Macs, so Apple silicon users must pick the ARM download.
  • Because it is not a VS Code fork, some extensions that rely on newer VS Code APIs may not work, so test your must-have ones before moving a team.

Visual Studio Code

Sometimes the honest answer is Microsoft's own build. Only it can install Remote SSH, Dev Containers, WSL and the C# and C/C++ debuggers, because Microsoft licenses those extensions for the official product. The FAQ says it is free for private and commercial use.

You also get new features first. Microsoft now tags a new release every week, per the VS Code tags, and version 1.145 shipped on November 4, 2026. Our VS Code alternatives guide covers the rest of the family, including AI-first forks.

Best for: Developers who need Microsoft's remote or debugger extensions and can accept a proprietary licence.

Pricing:

  • Free for private and commercial use

Watch out for:

  • The binary is under a Microsoft product licence, not MIT, and telemetry is on until you set telemetry.telemetryLevel to off. The setting does not cover what extensions collect.

Neovim

Neovim suits VSCodium users who already run a Vim extension and keep wishing it were the real thing. It is a terminal editor with a built-in LSP client and Lua configuration. Version 0.12, released in March 2026, added a built-in plugin manager, as AlternativeTo reported.

The newest release on GitHub is 0.12.6 from October 9, 2026, with a Windows MSI, a macOS tarball and Linux AppImages for x86_64 and arm64. No company account, store or telemetry is involved.

Best for: Keyboard-first developers who want an editor that works the same over SSH as on their laptop.

Pricing:

  • Free and open source

Watch out for:

  • There is no official GUI in the release assets, and you assemble the IDE yourself from plugins and language servers. Expect a few evenings of setup.

Kate

Kate is a native Qt app from KDE, so it skips the Electron memory cost entirely. The feature list covers what most VSCodium users rely on day to day: LSP completion, a project sidebar, split views, an embedded terminal, multi-cursor editing and 400+ languages.

Like VSCodium, it has no account and no telemetry to switch off. Wikipedia lists LGPL and MIT terms, and Windows builds are on the Microsoft Store.

Best for: Linux users who want a lighter native editor with the core IDE features and no extension store to manage.

Pricing:

  • Free and open source

Watch out for:

  • The macOS downloads are nightly builds the get-it page recommends for testing only.
  • There is no extension marketplace. If a language server or tool is not covered by Kate's built-in plugins, you configure it by hand.

Pulsar

Pulsar is the community fork of Atom, the editor VS Code replaced at GitHub. It is still Electron-based and fully community run. It has its own package repository and builds for Windows, macOS and Linux on the project site.

The Pulsar blog shows steady releases: 1.131.0 moved to Electron 30 in February 2026 and 1.132.0 added a core terminal package in May. On GitHub, 1.133.0 moved to Electron 32.3.3 on October 29, 2026, and 1.133.1 followed on November 1 with a fix for a Linux renderer crash. Themes and UI tweaks are plain CSS and JavaScript you can edit live.

Best for: People who liked Atom's hackable UI and want an Electron editor with no corporate parent at all.

Pricing:

  • Free and open source

Watch out for:

  • The project's own Electron 30 post warns that some community packages may need updates, and many Atom-era packages are unmaintained.

GNU Emacs

For licence purists, Emacs is the GNU Project's own editor and about as free as software gets. Version 31.1 appeared on the GNU FTP server on August 24, 2026, a year after 30.2.

The download page lists distro packages for Linux, a Windows installer or zip from GNU mirrors, and Homebrew, MacPorts or emacsformacosx.com for macOS. Everything, including the editor's own commands, can be changed in Emacs Lisp.

Best for: Developers who want one GPL tool for code, notes and Git, and do not mind learning Emacs Lisp.

Pricing:

  • Free and open source (GPL)

Watch out for:

  • Default keybindings are nothing like VS Code's, and a good setup takes weeks of tuning. Vim users usually add the Evil package.

Helix

Helix gives you a working IDE in the terminal with almost no configuration. The Helix site lists tree-sitter highlighting, built-in LSP, a fuzzy file finder, project search and Kakoune-style multiple selections, all on by default.

It is written in Rust and installs through Winget, Scoop, Homebrew, Flatpak, Snap and most Linux package managers, per the install docs. The latest release on GitHub is 25.07.1 from July 2025.

Best for: Terminal users who want modal editing and language servers working on day one without a plugin setup.

Pricing:

  • Free and open source (MPL-2.0)

Watch out for:

  • There is no plugin system yet. The Helix site says one is planned but gives no timeline.
  • Releases are infrequent, with no tagged release since July 2025.

When to stay with VSCodium

Stay with VSCodium if your extensions are on Open VSX and you do not need Microsoft's remote or debugger extensions. It keeps the VS Code interface, your settings.json and your keybindings, with MIT-licensed binaries and telemetry off. A lag of a few versions behind Microsoft rarely matters for daily work.

Frequently asked questions

What is the difference between VSCodium and VS Code?

VSCodium builds the same open source code without Microsoft's branding, licence and telemetry. It installs extensions from Open VSX instead of the Visual Studio Marketplace, and a few Microsoft extensions, such as Remote Development, only work in VS Code.

What is the best open source alternative to VSCodium?

Eclipse Theia IDE if you want to keep using VS Code-style extensions. Zed if you want a faster editor and can live without that catalogue. Neovim or Helix if you work in the terminal.

Is VSCodium still maintained?

Yes. The project published 1.143.17232 on October 28, 2026, based on VS Code 1.143.1. Before that came 1.140 earlier in October, 1.135 in September and 1.126 in July.

Can I use VS Code extensions outside VSCodium?

Eclipse Theia IDE installs them from Open VSX, as VSCodium does. Zed, Neovim, Kate, Emacs and Helix do not run VS Code extensions, though all of them can use the same language servers.
