description VS Code Web Overview
VS Code for the Web brings Microsoft's familiar code editor into a browser without requiring a desktop installation. It supports browsing repositories and making lightweight edits, with features such as syntax highlighting and language assistance. Web-compatible extensions can add functionality, making it useful for learning JavaScript or reviewing a small web project on a machine without a configured development environment. The browser version preserves much of the editor's interface, but it cannot automatically provide everything available in desktop VS Code.
Extensions that need a local runtime may not work, and ordinary local execution or debugging requires a suitable supporting environment. Its strength is convenient access to source files and familiar editing tools. It suits quick changes and educational work, while larger development tasks may need desktop or remote computing resources.
help VS Code Web FAQ
What is the difference between vscode.dev and GitHub Codespaces?
vscode.dev is VS Code running in the browser for lightweight editing, often without a full backend machine. GitHub Codespaces, launched by GitHub as a cloud development environment, gives you a hosted container where you can run builds, terminals, and server processes.
Can VS Code Web open local files?
VS Code for the Web can open local files in supported browsers, but browser security limits what it can do compared with the desktop app. The desktop VS Code, first announced by Microsoft in 2015, remains stronger for terminals, native debugging, and local toolchains.
Do normal VS Code extensions work in the browser version?
Some extensions work in VS Code Web, especially language and theme extensions that run fully in the browser. Extensions that require Node.js, local binaries, or direct filesystem access often need desktop VS Code or a remote environment like Codespaces.
Why do GitHub repositories open in github.dev?
github.dev is a browser editor for GitHub repositories that uses the VS Code interface for quick edits and pull-request work. It is lighter than Codespaces because it does not automatically give you a full cloud VM or dev container.
