## What it is
The open source ActionScript codebase for the Scratch 2.0 visual programming editor and player, used for both the online and offline Scratch editors. It is now in maintenance mode as development has moved to Scratch 3.0.

## Use cases
- build a visual block-based programming editor for kids
- fork Scratch 2.0 to create a custom educational coding environment
- fix bugs in the Scratch 2.0 offline editor
- study how a block-based visual language interpreter is implemented
- embed a Scratch project player in a website

## When to choose
- you need to maintain or patch a legacy Scratch 2.0 deployment
- you want to fork a proven block-based editor for educational software
- you need to understand the internals of Scratch 2.0

## When to avoid
- you want to build on the current Scratch platform - use Scratch 3.0 (scratch-gui) instead
- you need a modern web-based editor without Flash-era dependencies
- you expect new features or active community development

## Facets
- artifact type: application
- maturity: maintenance
- function: gui, interpreter, programming-language
- domain: education, programming-languages
- platform: cross-platform
- tags: scratch, actionscript, flash, visual-programming, kids-coding, block-based-programming, game-development, web-server, desktop
