Best Serverless and Edge Function Platforms in 2025

Top serverless and edge compute platforms in 2025 — compared on cold starts, global reach, pricing, and runtime support.

Serverless and edge function platforms let you run code without managing servers, often close to your users. The key differences are runtime (V8 isolates vs containers), global reach, cold start behaviour, and storage options. Here are the leading platforms with verified pricing as of May 2025.

#1

Cloudflare Workers

Top Pick

V8 isolates across 330+ PoPs — zero cold starts

Cloudflare Workers runs JavaScript, TypeScript, Python, and Rust (via WASM) on V8 isolates globally. No cold starts, 330+ points of presence, and a rich storage ecosystem (KV, R2, D1, Durable Objects).

Pricing

Free: 100,000 requests/day. Workers Paid: $5/mo for 10M requests/mo then $0.30/M.

Best for

Edge middleware, API routing, and compute-light serverless functions

Strengths

  • Zero cold starts via V8 isolates
  • 330+ global PoPs
  • Native KV, R2, D1 storage
#2

PandaStack Edge Functions

OpenWhisk-powered edge functions alongside full-stack hosting

PandaStack edge functions run on Apache OpenWhisk and support Node.js, Python, and Go. Unlike pure edge platforms, your functions live alongside your containers, databases, and cron jobs — no separate platform needed.

Pricing

Included in PandaStack plans. Free plan available.

Best for

Teams already on PandaStack that want edge functions without a second platform

Strengths

  • Co-located with containers and databases
  • Multiple runtimes (Node, Python, Go)
  • Function invocation tokens
#3

Deno Deploy

TypeScript-first global serverless with built-in KV storage

Deno Deploy runs TypeScript and JavaScript on Deno isolates globally. Built-in Deno KV for global key-value storage, 1M requests/mo and 20 GB egress on the free plan.

Pricing

Free: 1M req/mo, 20 GB egress, 15 CPU-hours/mo, 1 GiB volume storage.

Best for

TypeScript-first teams wanting a generous free tier

Strengths

  • TypeScript-native runtime
  • 1M requests/mo free
  • Built-in Deno KV
#4

Vercel Edge Functions

Edge middleware tightly integrated with Next.js and Vercel deployments

Vercel Edge Functions run at the edge globally and integrate natively with Next.js Middleware. Best suited for teams already deploying on Vercel.

Pricing

Included in Vercel plans. Pro plan $20/seat/mo.

Best for

Next.js teams on Vercel needing edge middleware

Strengths

  • Native Next.js Middleware integration
  • Global edge deployment
  • Simple deployment from Vercel dashboard
#5

AWS Lambda@Edge / CloudFront Functions

Enterprise-grade serverless at the edge via AWS infrastructure

AWS offers two serverless edge products: Lambda@Edge (full Lambda at CloudFront edge, 128 MB–10 GB RAM) and CloudFront Functions (lightweight JS-only, sub-millisecond execution). Powerful but more complex to configure.

Pricing

Lambda@Edge: $0.60 per 1M requests + $0.00000625125/GB-second. CloudFront Functions: $0.10/M requests.

Best for

Enterprises already on AWS infrastructure

Strengths

  • AWS ecosystem integration
  • High request volume pricing
  • Both lightweight and full-Lambda options
