Fastly

Programmable edge cloud platform for content delivery, edge compute, security, and observability. Delivers sites and APIs from the network edge with real-time cache control, instant purge, and code execution in VCL, Rust, Go, or JavaScript.

Trusted by GIPHY, 1stdibs, Kubernetes, and GitHub. Named Gartner Customers' Choice for Web Application and API Protection seven years running and IDC Leader in Edge Delivery Services.

• Next-Gen WAF and DDoS protection
• Real-time observability and Edge Observer dashboards
• Terraform provider and API clients for CI/CD integration

Teams use Fastly for ecommerce and retail where real-time inventory and fast checkout matter, streaming media with low-latency delivery, digital publishing with instant content updates, and SaaS or API platforms that need edge-side logic for personalization, auth, or geolocation.
