## What it is
Editr.js is a self-hosted HTML, CSS and JavaScript playground built on ACE Editor, embeddable on your own server via a simple HTML element and JS configuration. It supports multiple instances per page, Emmet, preprocessors like LESS and CoffeeScript, GitHub Gist loading, and read-only presentation modes.

## Use cases
- host my own code playground like codepen on my server
- embed live html css js demos in blog posts
- self-hosted jsfiddle alternative
- show interactive code examples on documentation site
- embed editable code demo with live preview
- present code snippets in read-only mode
- load demo files from github gists

## When to choose
- you want a CodePen/jsFiddle-style playground hosted on your own server
- you need to embed multiple live code demos on a single page
- you want full control over editor styling and file storage
- you need Emmet, themes, or preprocessor support in an embedded editor

## When to avoid
- you need a full cloud IDE or server-side file editing
- you need SASS compilation support
- you want a maintained solution with an active community and license
- your stack avoids jQuery or legacy dependencies
