Serverless functions

12 services

Serverless free tiers count requests or invocations, and the period matters as much as the number. AWS Lambda and Azure Functions each include 1M requests a month. Cloudflare Workers and Deno Deploy both cap at 100,000 requests a day, which suits steady traffic but not bursts; Deno Deploy adds 100 GB of transfer a month. ampt.dev stacks three caps at once: 50,000 invocations a month, 2,500 a day and 500 an hour. Edge runtimes also limit CPU time per request, so heavy work may not fit even within the request quota.

For long-running or multi-step jobs, durable workflow engines are a better fit than plain functions. Inngest includes 50,000 executions and 500,000 events a month with no card. Trigger.dev gives $5 of compute credit a month with 20 concurrent runs and is open source. Val Town runs TypeScript snippets as endpoints or scheduled jobs, with cron as often as every 15 minutes and 1 minute of runtime per run. Modal targets Python and GPU workloads with a $30 monthly credit, though some accounts get $5.
