Which Should You Choose?

Choose Bun if:

  • •You need a JavaScript runtime for your application server
  • •You want fast local builds, tests, and server execution
  • •You are choosing a runtime, not a CDN or edge platform

Choose Fastly if:

  • •You need a programmable enterprise CDN with VCL or Compute@Edge
  • •You want real-time cache purging and edge logic at global scale
  • •Your app serves high-traffic media or APIs requiring consistent low-latency delivery

Fastly is an enterprise CDN and edge platform; Bun is a JavaScript runtime. They solve different problems. Fastly's Compute@Edge can run JavaScript at the edge, so there is a narrow overlap for edge JS. For application server code, Bun is the right tool. For CDN-level distribution and cache management, Fastly is the right tool. Most teams need both.
