Cloudflare Workers: The Edge Platform

Strengths

300+ locations. The largest edge network. Your code runs within 50ms of 95% of the world's internet-connected population. No other platform matches this distribution.

Sub-millisecond cold starts. V8 isolates start almost instantly. No container spin-up. The first request is as fast as the thousandth.

Full storage ecosystem:

• KV: Global key-value store (eventually consistent)
• R2: Object storage (S3-compatible, zero egress fees)
• D1: SQLite at the edge
• Durable Objects: Stateful, single-instance compute (real-time collaboration, WebSockets)
• Queues: Message queues
• Hyperdrive: Connection pooling to external databases

Durable Objects are unique. No other edge platform offers single-instance stateful compute. Build: real-time collaboration, WebSocket servers, rate limiters, and stateful workflows — at the edge.

Cron Triggers. Schedule Workers to run on a cron schedule. Background tasks at the edge.

export default {
  async fetch(request: Request, env: Env) {
    const data = await env.KV.get('key');
    return new Response(data);
  },
  async scheduled(event: ScheduledEvent, env: Env) {
    // Runs on cron schedule
    await env.KV.put('key', 'updated');
  },
};

Weaknesses

• Not full Node.js. Many Node.js APIs don't work (fs, net, child_process). npm compatibility is improving but not complete.
• CPU limits. 10ms CPU time (free) / 30s (paid). CPU-intensive tasks (image processing, heavy computation) may hit limits.
• Bundle size limit. 1MB free / 10MB paid (after compression). Large dependencies are problematic.
• Debugging. Local development (wrangler dev) works but doesn't perfectly replicate the edge environment.

Pricing

	Free	Paid ($5/mo)
Requests	100K/day	10M/mo included
Overage	—	$0.30/million
CPU time	10ms	30ms-15min
KV reads	100K/day	10M/mo

Best For

API backends, middleware, A/B testing, authentication at the edge, real-time applications (Durable Objects), and global content delivery.

Vercel Edge: Next.js Native

Strengths

Next.js integration. Edge functions in Next.js are first-class:

// app/api/hello/route.ts
export const runtime = 'edge';

export async function GET(request: Request) {
  return new Response(JSON.stringify({ hello: 'world' }));
}

One line (export const runtime = 'edge') moves your function from serverless to edge. Seamless.

Edge Middleware. Run code before every request:

// middleware.ts
export function middleware(request: NextRequest) {
  // Runs at the edge on every request
  if (!isAuthenticated(request)) {
    return NextResponse.redirect('/login');
  }
}

Authentication, geolocation, A/B testing, redirects — all at the edge with zero latency overhead.

Edge Config. Ultra-low-latency key-value store for feature flags and configuration. Read in ~1ms from any edge location.

Vercel ecosystem. Analytics, Speed Insights, image optimization, ISR — all integrated. If you're on Vercel, edge functions are natural.

Weaknesses

• Vercel-centric. Edge functions are deeply tied to Vercel's platform. Moving to another host means rewriting.
• Limited compute. 30-second execution limit. No long-running tasks.
• Fewer edge locations. ~20 regions vs Cloudflare's 300+. Adequate for most applications but not as globally distributed.
• No stateful compute. No Durable Objects equivalent. Stateless only.
• Pricing complexity. Edge function invocations are part of your Vercel plan. Overages on Pro plan: $2/100K invocations.

Pricing

Included in Vercel plans:

Plan	Edge Invocations
Hobby	100K/mo
Pro ($20/user/mo)	1M/mo
Enterprise	Custom

Best For

Next.js applications. Middleware (auth, redirects, A/B testing). Teams already on Vercel. Edge rendering of dynamic content.

Deno Deploy: Simplicity First

Strengths

Simplest deployment. Write a TypeScript file → deploy:

Deno.serve((req: Request) => {
  return new Response("Hello from the edge!");
});

deployctl deploy --project=my-app main.ts

Deno-native. Full Deno API: TypeScript out of the box, top-level await, Web Standard APIs, and npm package support via npm: specifier.

Deno KV. Built-in key-value database with strong consistency:

const kv = await Deno.openKv();
await kv.set(["users", "123"], { name: "John" });
const user = await kv.get(["users", "123"]);

SQLite-backed locally, globally distributed on Deno Deploy.

GitHub integration. Push to GitHub → auto-deploy. No CI configuration.

Generous free tier. 100K requests/day, 512MB storage, KV included.

Weaknesses

• Deno ecosystem. While npm compatibility exists, some packages don't work. Deno-first packages are growing but smaller than Node.js.
• Fewer regions. 35+ regions (good, but less than Cloudflare).
• Less mature. Newer platform with fewer production case studies.
• Limited storage options. Deno KV only. No object storage, no queues, no durable objects.
• Framework support. Fresh (Deno's framework) and Hono work well. Next.js doesn't run on Deno Deploy.

Pricing

Plan	Price	Includes
Free	$0	100K req/day, 512MB KV
Pro	$20/mo	5M req/mo, 5GB KV
Enterprise	Custom	Custom

Best For

Simple APIs and microservices. Deno projects. Developers wanting the simplest deployment experience. Edge functions that need a built-in database (Deno KV).

FAQ

Can I use Node.js packages at the edge?

Cloudflare: growing support via node: compat. Vercel Edge: limited Node.js API support. Deno: npm: specifier for most packages. All three have limitations — not every Node.js package works at the edge.

Which is fastest?

Cloudflare Workers (sub-ms cold starts, 300+ locations). But for most applications, all three are "fast enough" — the difference is milliseconds.

Can I migrate between edge platforms?

If your code uses Web Standard APIs (Request, Response, fetch): migration is straightforward. Platform-specific features (KV, Durable Objects, Edge Config) require rewriting.

Do I need edge compute?

For global applications where latency matters: yes. For applications serving one region: standard serverless is fine and simpler. Edge adds complexity — use it when the latency improvement justifies it.

Bottom Line

Cloudflare Workers for the most capable edge platform. Best network, most storage options, unique features (Durable Objects). The default for serious edge applications.

Vercel Edge for Next.js applications. Seamless integration, edge middleware, and the Vercel ecosystem. Don't use it standalone — it's best as part of a Vercel deployment.

Deno Deploy for simplicity. Deploy a TypeScript file with built-in KV database. Best for microservices and simple APIs that need global distribution.
