Serverless Function Deployment Without AWS: A Practical Comparison

AWS Lambda redefined how teams think about compute. But the Lambda programming model — IAM roles, deployment packages, VPC configuration, CloudWatch logs scattered across a dozen pages — carries a significant ops overhead. In 2026, there are genuinely excellent alternatives for teams that want serverless compute without the AWS tax.

What We're Comparing

This comparison focuses on five criteria that matter to application developers:

1. Cold start latency
2. Developer experience (local dev, deployment, logs)
3. Runtime support and limits
4. Pricing model
5. Ecosystem integrations

Cloudflare Workers

Cloudflare Workers runs on V8 isolates distributed across 300+ edge locations globally. Cold starts are under 5ms because isolates don't require container spin-up. The trade-off: you're restricted to the Web APIs subset — no native Node.js fs, net, or most npm packages that rely on native bindings.

Best for: Ultra-low-latency edge logic, A/B testing, authentication middleware.

Pricing: 100k requests/day free. $5/month for 10M requests.

Vercel Edge Functions

Vercel's edge runtime is built on the same V8 isolate model as Cloudflare Workers. The integration with Next.js is seamless — deploy an edge function by adding export const runtime = 'edge' to any API route. Logs appear in the Vercel dashboard instantly.

Best for: Next.js applications, SSR personalisation, geo-routing.

Pricing: Generous free tier; scales with Vercel Pro at $20/month.

Deno Deploy

Deno Deploy runs Deno (TypeScript-first, secure-by-default) functions globally. First-class TypeScript support without a build step is the headline feature. Global KV storage and message queues are built in. The npm compat layer handles most packages but isn't perfect.

Best for: TypeScript-native teams, projects using Deno's standard library.

Pricing: Free for 1M requests/month. Generous paid tier.

moqapi.dev Serverless Functions

moqapi.dev targets a different use case: application logic functions organised around API projects. Write functions in a browser IDE, attach shared dependency layers, bind them to API Gateway routes, and invoke them via HTTP or cron schedule. Logs are unified across functions, API calls, and webhook deliveries in a single viewer.

Best for: Teams that want full-stack API management (mock APIs + real serverless + crons + webhooks) in one platform without a cloud account.

Pricing: Free tier available.

The Comparison Table

Platform	Cold Start	Runtime	Free Tier	DX Score
AWS Lambda	100ms–1s	Node, Python, Go, Java, Ruby	1M req/month	3/5
Cloudflare Workers	<5ms	V8 (Web APIs)	100k req/day	4.5/5
Vercel Edge	<5ms	V8 (Web APIs)	Generous	5/5 (Next.js)
Deno Deploy	<5ms	Deno / TypeScript	1M req/month	4/5
moqapi.dev	Low	Node.js / JS	Free tier	4.5/5

How to Choose

If your workload is latency-sensitive and globally distributed, Cloudflare Workers or Vercel Edge are hard to beat. If you're building TypeScript-first and want to avoid build tooling, Deno Deploy is excellent. If you want a complete platform for mock APIs, API Gateway, cron jobs, webhooks, and serverless functions under one roof — without wiring up five different AWS services — moqapi.dev is worth a serious look.
