Ship to the edge.
Everywhere at once.
Relay serves and runs your code from 340+ cities in 128 countries. Static, dynamic, and streaming, answered from the point of presence nearest your visitor, in single-digit milliseconds.
Measured from where your users actually are.
Live p95 latency sampled from real client requests over the last 60 seconds. No single-region fallbacks, no cold origins. Every edge holds a warm copy.
One network. Every layer of the request.
CDN, compute, security, and DNS answered from the same node, so a request never leaves the edge to be resolved, cached, filtered, or rendered.
Smart tiered caching
Content is pinned across regional shields, so origin fetches drop to near zero. Tag-based purge propagates worldwide in under 150ms.
98.7% cache hit ratioEdge Functions
Deploy JavaScript, TypeScript, and WASM to every POP. V8 isolates boot in under 5ms with zero cold starts. No containers, no regions to pick.
<5ms isolate bootAlways-on DDoS shield
248 Tbps of absorption capacity mitigates L3–L7 floods at the edge before they reach your origin. Rules update globally in seconds.
248 Tbps capacityEdge KV & cache API
Strongly-consistent key-value storage replicated to every region. Read your data from the same isolate handling the request. No round trip.
<1ms local readsAnycast & instant DNS
A single anycast address routes each visitor to the closest healthy node. Authoritative DNS resolves in a median of 9ms worldwide.
9ms median resolveReal-time analytics
Per-request logs, latency histograms, and cache diagnostics stream to your dashboard with sub-second lag. Query 30 days of edge traffic.
<1s log latency// runs in every one of 340+ cities export default async function handler(req) { const geo = req.cf.geo; // resolved at the edge const hit = await Relay.KV.get(geo.city); if (hit) return new Response(hit, { headers: { "x-relay-pop": geo.pop } }); const data = await render(geo); // <5ms isolate Relay.KV.put(geo.city, data, { ttl: 3600 }); return new Response(data); }
Push once. Run in every city.
One relay deploy ships your function to the entire fleet. No region selection, no autoscaling config, no idle instances. The code lives where your users are and scales to the request.

From click to byte in four hops.
Every request rides the same optimized path: resolved, routed, filtered, and answered without ever leaving Relay's backbone.
Anycast resolve
DNS points your visitor to the single nearest POP via one anycast IP, 9ms median, worldwide.
Shield & filter
L3–L7 mitigation and WAF rules run inline at the edge, dropping hostile traffic before it costs you.
Cache or compute
A warm cache answers instantly; a miss spins a V8 isolate in under 5ms and stores the result nearby.
Stream back
The response streams over HTTP/3 from the same node. No backhaul, no origin round trip.
Priced by traffic, not by region.
Bandwidth is metered flat, worldwide. No per-region multipliers, no egress traps. The same rate whether your users are in Ohio or Osaka.
