CodeSandbox
Browser-based development environment for React, Vue, Angular, and more. Instant previews, collaborative editing, deploy with one click. Ideal for prototyping and sharing demos. It boots a full npm dependency tree in the browser, so a shared link opens a running project rather than a snippet.
CodeSandbox opens in a browser tab — no download.
Not sure how to add CodeSandbox to your home screen? Step-by-step for Chrome, Safari, Firefox and Edge — it takes about ten seconds, and there is no app store involved.
