BootstrapCDN

BootstrapCDN is a free content delivery network (CDN) providing production-ready hosting for popular front-end web development libraries. It serves as the recommended CDN for Bootstrap, Font Awesome, Bootswatch themes, and Bootstrap Icons, making it a go-to resource for web developers who need reliable, fast-loading assets.

Services

  • Bootstrap — CSS framework (v5.3.3, v4.6.2, and older versions)
  • Font Awesome — Icon library
  • Bootstrap Icons — Official Bootstrap icon set
  • Bootswatch — Free Bootstrap themes
  • Bootlint — Code quality tools for Bootstrap projects

The service is operated by jsDelivr and powered by the Globalping network testing platform. Major sponsors include Cloudflare, Fastly, NS1, BunnyCDN, and developer Dmitriy Akulov.

Infrastructure

  • DNS: Cloudflare nameservers (brenda.ns.cloudflare.com, keenan.ns.cloudflare.com)
  • CDN: Cloudflare network (IPs: 104.18.10.207, 104.18.11.207)
  • IPv6: Fully supported (2606:4700::6812:acf, 2606:4700::6812:bcf)
  • Protocols: HTTP/2 and HTTP/3 enabled
  • DNSSEC: Not signed

Legacy subdomains (maxcdn.bootstrapcdn.com, stackpath.bootstrapcdn.com, netdna.bootstrapcdn.com) reflect the service's historical association with MaxCDN/StackPath before transitioning to its current jsDelivr-operated infrastructure.
