Serverless pricing rankings

These rankings answer the questions people ask most about serverless cost: which platform has the most generous free tier, which ones scale to zero (so idle costs nothing), and which are cheapest per million requests and per GB-second. For most small workloads the practical cheapest answer is the free tier — Lambda, Cloudflare Workers and Cloud Run all run light apps at $0.

Data as of June 2026.

Most generous free tier

Which serverless platforms give the most away for free every month — the question side projects ask first.

Scale-to-zero platforms

Platforms that cost $0 while idle (pay only for actual usage) versus those that bill while running.

Cheapest per 1M requests

Request-priced FaaS ranked by the fee per million requests, from $0.20 (Lambda) up.

Cheapest per GB-second

GB-second-metered platforms ranked by the memory-time rate that usually dominates a serverless bill.
