CodeSwing is a VS Code extension that provides an interactive coding playground for building web applications ('swings') with live preview as you type. It brings the CodePen/JSFiddle experience directly into the editor, supporting HTML, CSS, JavaScript/TypeScript, and popular frameworks without any build tooling.

Use cases

  • prototype web apps with live preview inside VS Code
  • experiment with HTML/CSS/JS snippets like CodePen but in my editor
  • learn web development with interactive tutorials and guided walkthroughs
  • build React or Vue demos without setting up a bundler
  • share code snippets by exporting swings to CodePen
  • manage playground snippets as GitHub Gists

When to choose

  • you want a CodePen-like playground integrated into VS Code with your themes and extensions
  • you need instant live preview while editing web code without any build configuration
  • you teach or learn front-end concepts with runnable, editable examples

When to avoid

  • you need a full production web build pipeline with bundling and optimization
  • you are not a VS Code user
  • you need backend or server-side playgrounds rather than client-side web code
