Pick your edge runtime — 10 options across the five categories that decide most picks
Your edge runtime decides whether your AI streams in 50ms or 500ms, whether your bandwidth bill is reasonable or punishing, and whether your team writes V8-isolate code or Docker containers. Filter by V8 isolate / serverless / WASM / CDN-function / JS runtime, plus pricing and Node compatibility.

Showing 10 of 10
Bun
Fast JS runtime. Not edge-native but ships everywhere — pair with edge platforms via standard fetch.
WasmEdge
CNCF WebAssembly runtime for cloud and edge. Tiny footprint, polyglot, infra-flavoured.
Cloudflare Workers
V8 isolates on 300+ PoPs. Sub-millisecond cold starts, lowest cost at scale, the edge default.
Vercel Edge Functions
V8 isolates inside Vercel. Tight Next.js integration, smaller PoP network than Cloudflare.
Deno Deploy
V8 isolates from the Deno team. Web-standard APIs, cleaner runtime than Node.
AWS Lambda@Edge
AWS Lambda functions running on CloudFront. Full Node, slow cold starts, AWS-locked.
AWS CloudFront Functions
Sub-millisecond JS at CloudFront edge. Lighter than Lambda@Edge, narrower scope.
Fastly Compute
WASM-based edge compute. Multi-language (Rust, Go, AssemblyScript), enterprise-shape.
Akamai EdgeWorkers
JavaScript at the Akamai edge. Enterprise CDN-attached compute, narrower runtime.
Fly.io Machines
Docker containers at 30+ regions. Heavier than V8 isolates, full Node + binary support.

The runtime choice is the easy half — your platform integration is the hard one
Picking the runtime is the easy half. The hard half is integrating with your existing data layer, your auth, your build pipeline, and your monitoring. The 30-min call is where you describe your stack and your latency budget; I tell you what fits.
