## What it is
DartPad is a free, open-source online editor for writing, compiling, and running Dart and Flutter code directly in the browser. It includes a backend compilation service, a web frontend UI, and supports embedding in other websites via iframe.

## Use cases
- try out Dart code snippets in the browser without installing anything
- learn Dart and Flutter with an interactive online playground
- run and preview Flutter web apps online
- embed a live Dart code editor in documentation or tutorials
- share runnable Dart code snippets with others
- experiment with console and web Dart apps quickly

## When to choose
- you want to experiment with Dart or Flutter without a local SDK setup
- you need an embeddable, runnable code editor for Dart tutorials or docs
- you are teaching or learning Dart and want instant compile-and-run feedback

## When to avoid
- you need a full-featured local IDE with debugging, refactoring, and package management
- your project requires private code execution or offline compilation
- you need to run Dart code outside the browser sandbox with native dependencies
