## What it is
nude.js is a client-side JavaScript nudity detection library that analyzes image data via HTMLCanvas using algorithms based on research papers. It runs entirely in the browser, letting developers decide whether to display images flagged as containing nudity.

## Use cases
- detect nude images in the browser before displaying them
- build a client-side content filter for a web proxy
- scan user-uploaded images for nudity on a social platform
- filter inappropriate images for child-safe browsing
- check images or video frames for nudity without a server

## When to choose
- you need nudity detection that runs entirely client-side in JavaScript
- you want a lightweight, dependency-free scanner using HTMLCanvas
- you need to support legacy browsers including IE9

## When to avoid
- you need high accuracy modern detection - use an ML-based NSFW classifier instead
- you need server-side or Node.js scanning
- you need an actively maintained project with a license
