BootstrapCDN is a free CDN hosting the Bootstrap framework and Font Awesome icons, now powered and maintained by jsDelivr infrastructure.
BootstrapCDN is a free, publicly hosted content delivery network that serves the Bootstrap front-end framework's CSS and JavaScript files, along with the Font Awesome icon library, so that developers do not need to download, host, or update these assets themselves. It was launched in 2012 by David Henzel and Justin Dorfman while they were at MaxCDN, and quickly became one of the most widely referenced public CDNs on the web due to Bootstrap's popularity.
The service works on a simple model: developers copy a link or script tag pointing to a BootstrapCDN-hosted file into their HTML, and the browser fetches that file from the nearest edge server rather than from the developer's own hosting infrastructure. Because so many sites reference the same public URLs, browsers can also benefit from shared caching across different websites using the identical CDN link.
In a significant operational change, BootstrapCDN moved under the stewardship of jsDelivr around 2021. jsDelivr assumed full ownership of the bootstrapcdn.com domain and migrated the underlying delivery infrastructure while preserving every previously issued hostname, so legacy code referencing old MaxCDN or StackPath-branded BootstrapCDN URLs continues to function without any changes required from site owners.
The core feature of BootstrapCDN is free, always-current hosting of the Bootstrap framework's compiled CSS and JavaScript bundles across multiple Bootstrap versions, letting developers pin to a specific release or track the latest stable build via a hosted URL.
It also hosts Font Awesome, the widely used icon library, meaning a single service covers two of the most common front-end dependencies used in traditional multi-page websites and legacy jQuery-based projects.
Under jsDelivr's operation, the service benefits from a modern CDN stack: Cloudflare handles DNS and edge traffic routing, origin files are stored in Amazon S3, and BunnyCDN provides origin shielding, URL rewriting, and HTTP header management, giving the free service enterprise-grade reliability and global edge coverage.
BootstrapCDN is entirely free to use for any website or project; there is no paid tier, subscription, or usage-based billing for developers linking to its hosted Bootstrap or Font Awesome files.
The service is funded as open infrastructure rather than a commercial product, similar to how jsDelivr funds its broader open-source CDN network through sponsorships and its own backing infrastructure providers rather than charging end users.
Because there is no account system or paid plan, there is nothing to sign up for or subscribe to; developers simply reference the public CDN URLs directly in their project's markup.
