## What it is
CodePan is a browser-based web playground for experimenting with HTML, CSS, and JavaScript, similar to CodePen and JSBin. It is a single-page, no-backend app that works fully offline via service-worker caching.

## Use cases
- run an offline code playground in the browser
- quickly test html css and js snippets
- prototype frontend code without a server
- experiment with javascript in a sandboxed editor
- use a codepen alternative that works without internet

## When to choose
- you need a code playground that works offline
- you want a self-hosted, no-backend JSBin/CodePen alternative
- you just need to scratch-test frontend snippets quickly

## When to avoid
- you need collaborative or cloud-saved playgrounds
- you need server-side language support or backend execution
- you need a maintained tool with active development

## Facets
- artifact type: application
- maturity: maintenance
- function: frontend-framework, developer-tools
- domain: web-development, frontend, developer-tools
- platform: browser
- tags: code-playground, offline-first, spa, no-backend, vue, webpack, pwa, web-server
