## What it is
logdown is a small debug logging library for JavaScript that works in both the browser and Node.js, wrapping the console with Markdown formatting support. It provides a unified logger interface similar to debug.js, controlled via NODE_DEBUG or localStorage.debug.

## Use cases
- add colored markdown-formatted debug logging to a node app
- debug logging in the browser with devtools-friendly output
- unified logging interface across browser and server code
- enable/disable loggers via NODE_DEBUG or localStorage
- lightweight 2KB debug alternative to debug.js

## When to choose
- you want debug-style logging with markdown formatting in both browser and Node
- you need a tiny dependency-free browser logging utility
- you want debug.js-style namespace filtering with nicer output

## When to avoid
- you need structured log aggregation or log shipping to external systems
- you need log levels, transports, or file output like winston or pino
- you need an actively developed library with recent releases
