## What it is
CodeSandbox is an online IDE for rapid web development that runs entirely in the browser, letting users create, run, and share web app projects instantly. The client is the open-source web application powering codesandbox.io, supporting frameworks like React, Vue, Angular, Svelte, and Preact.

## Use cases
- prototype a react app in the browser without local setup
- share a runnable code example with teammates
- try out vue or svelte quickly
- run and test frontend code online
- create web app sandboxes for teaching
- embed live code demos in documentation

## When to choose
- you want zero-setup web development in a browser
- you need to share runnable frontend examples quickly
- you're prototyping with popular JS frameworks

## When to avoid
- you need a fully offline or self-hosted IDE
- you work primarily with backend or non-JS languages
- you need a nonstandard license for redistribution

## Facets
- artifact type: application
- maturity: active
- function: editor, web-framework, developer-tools
- domain: web-development, developer-tools
- platform: browser
