Ultra Edge Runtime

Ultra is a framework and runtime for deploying JavaScript/TypeScript code at the edge—on Cloudflare, Vercel, and other edge networks that have 100+ global locations. Instead of deploying to a single region (London, us-east-1), you deploy to edge nodes nearest users, cutting latency from 100–200ms to 10–30ms. You write request handlers in TypeScript, define routes, and deploy via CLI. Ultra handles routing, request/response handling, and environment variable management across edge nodes. It integrates with KV stores (caches) for fast data access and can make requests to regional databases or APIs for data not suitable for edge caching.
