AWS Lambda is rated higher (4.1 vs 3.5). AWS Lambda is the original FaaS service — run code without servers. Supports 15+ runtimes, 1M free requests/month, and integrates deeply with 200+ AWS services. Triggered by S3, DynamoDB, API Gateway, and more. Napkin lets you write and run Node.js and Python serverless functions directly in the browser with zero setup, deploying them as authenticated HTTP endpoints.

AWS Lambda
Pros
- + Zero idle cost with a free tier that covers small products: 1M requests and 400,000 GB-seconds monthly
- + Graviton pricing at $0.0000133334 per GB-second undercuts x86 by roughly 20%
- + Automatic multi-AZ scaling with a 99.95% per-region SLA and no capacity planning
- + Deep event integration across AWS services, with three form factors (Event/Web Functions, MicroVMs)
Cons
- - Per-request and GB-second pricing gets expensive against committed compute at steady high utilization
- - Cold starts — hundreds of milliseconds to seconds depending on runtime — with provisioned concurrency as an extra meter
- - 15-minute execution limit and payload caps make it wrong for long-running batch work
- - AWS-specific event plumbing creates real lock-in; distributed event chains are hard to debug
Napkin
Pros
- + Genuinely free plan: $0/month with 25,000 API calls, unlimited functions, custom domains, and team invites
- + One-click deploy from a browser editor — Node.js and Python, no cloud console or CLI required
- + Clear published limits: 500 MB/0.5 vCPU free (2 GB/2 vCPU Pro), 15s/30s timeouts, explicit rate caps
- + Endpoint SSL, auth, production logs, and scheduled triggers included on both tiers
- + Pro tier is capacity-only at $10 per user per month — no feature gating, no sales call
Cons
- - No published SLA, regions, or data residency; small-vendor reliability story
- - Free tier caps at 5 requests/second and a 15-second timeout — real design constraints
- - Browser-only workflow with no local development story and no obvious export path
- - Node.js and Python only — no Go, Rust, PHP, or Ruby runtimes
- - Stale limit figures circulate on marketing and third-party pages, so verify before budgeting
