Fastly vs Vercel Functions

Fastly

Fastly is a developer-centric edge cloud distinguished by instant cache purges (global purge in under 150ms), a powerful edge-compute platform (Compute@Edge with WebAssembly), and real-time log streaming. Built for engineering teams that need fine-grained control over caching logic and sub-millisecond cold starts at the edge, it powers some of the web's highest-traffic properties.

Vercel Functions

Vercel Functions are serverless and edge compute runtimes deeply integrated with the Vercel frontend deployment platform, offering zero-config deployments for Next.js, SvelteKit, and other frameworks. With automatic region routing, streaming responses, and a generous free tier, they enable frontend teams to add backend logic without managing infrastructure.
