## What it is
A small JavaScript library that generates GitHub-style identicon images from hash strings, outputting PNG or SVG formats. It supports customization of size, margin, colors, saturation, and brightness.

## Use cases
- generate default avatars for users without profile pictures
- create deterministic identicon images from hash values
- render GitHub-style identicons as PNG or SVG in the browser
- generate identicons server-side in Node.js
- customize identicon colors, size, and margins

## When to choose
- you need GitHub-style identicons in a JavaScript app
- you want lightweight client-side or server-side avatar generation from hashes
- you need both PNG and SVG output formats

## When to avoid
- you need identicons in a non-JavaScript language
- you need photo-based or AI-generated avatars
- you need exact GitHub-identical identicons from usernames (GitHub uses internal database identifiers, not username hashes)

## Facets
- artifact type: library
- maturity: maintenance
- function: image-processing, graphics
- domain: web-development, frontend, graphics
- platform: browser
- tags: identicon, avatar-generation, png, svg, github-style, nodejs, javascript
