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.
