vscode.dev brings VS Code to the browser. Open a folder on your local machine and start coding. No install required. It supports all major languages with some limitations.

• Good: For most programming languages, vscode.dev gives you code syntax colorization, text-based completions, and bracket pair colorization. Using a Tree-sitter syntax tree, we're able to provide additional experiences such as Outline/Go to Symbol and Symbol Search for popular languages such as C/C++, C#, Java, PHP, Rust, and Go.
• Better: The TypeScript, JavaScript, and Python experiences are powered by language services that run natively in the browser. With these programming languages, you'll get the "Good" experience plus rich single file completions, semantic highlighting, syntax errors, and more.
• Best: For many "webby" languages, such as JSON, HTML, CSS, and LESS, the coding experience in vscode.dev is nearly identical to the desktop (including Markdown preview!).
