## What it is
BootstrapCDN is a free content delivery network service hosting Bootstrap, Font Awesome, Bootswatch, and Bootstrap Icons, backed by jsDelivr. The repository contains the Express.js website that generates copy-paste CDN links with SRI hashes and exposes an API for version lookups.

## Use cases
- serve bootstrap css and js from a cdn
- get font awesome cdn links
- find latest bootstrap version via api
- load bootswatch themes from a cdn
- add sri hashes to bootstrap script tags
- speed up website by using a shared css cdn

## When to choose
- you need production-ready CDN links for Bootstrap, Font Awesome, Bootswatch, or Bootstrap Icons
- you want automatic minor-version aliasing without manual updates
- you need SRI hashes generated for you
- you want a free, high-availability CDN used by millions of sites

## When to avoid
- you need to host private or custom-built assets - it only serves published NPM packages
- you require strict GDPR-style control over third-party requests on your site
- you need a general-purpose CDN for arbitrary files - use jsDelivr directly
- you want pinned versions with SRI plus auto-updating aliases, which are mutually exclusive
