A 2026 comparison of serverless / FaaS pricing: price per million requests, per GB-second, free tiers and egress across AWS Lambda, Cloudflare Workers, Google Cloud Run, Vercel, Azure Functions and more.

Cold starts and pricing are linked: scale-to-zero saves money but adds latency, and wall-clock vs CPU-time billing changes what a cold start costs you. Here's how the models compare.

AWS Lambda and Cloudflare Workers price serverless very differently — GB-seconds vs CPU-milliseconds, $0.09/GB egress vs none. Here's which is actually cheaper, with a worked example.

Serverless looks free until the bill arrives. The real costs are egress, API gateways, NAT gateways, GB-seconds from over-provisioned memory, and platform minimums — here's what to watch.

Serverless wins on spiky, low-volume and bursty workloads; a $5 VPS wins on steady, always-on traffic. Here's the break-even logic and the numbers behind it.

For a side project the cheapest serverless is almost always $0 — here are the free tiers that actually let a small app run forever without a bill, ranked.
