Hi 👋, we're Fastly.

A montage of Fastly contributors made using Imagemagick

Fastly empowers everyone to build the good internet together.

With features ranging from DDoS and bot protection to caching and edge computing, we help make apps, websites, and connected devices faster, safer, and more engaging. We power GitHub Pages, the Linux Foundation, downloads of cURL, registries like RubyGems and PyPi, public CDNs like JSDelivr, and much more. We're BFFs with your refrigerator and your favorite news site.

At Fastly, open source is a part of our heritage, essential to our operations, and central to our future. Our core technologies are built on open-source code, and we use and contribute to the software and open internet standards that make the modern internet.

Fast Forward

To nurture and support those who share our vision of an open internet that is fast and secure for all, we extend free and deeply discounted services to eligible open source projects and the nonprofits that support them: Kubernetes, Mastodon, Rust, and over 100 more.
