Upstash QStash

Serverless HTTP message queue

Free tier + paidAutomation & background jobsupstash.com

What it is

A hosted queue and scheduler that speaks pure HTTP: you POST a job and QStash calls your endpoint later, with retries, delays up to a year, cron schedules, dead-letter queues and request signature verification. No connections, no workers, no Redis to operate.

Why it earns a slot

The simplest way to add background work to a serverless app: one fetch to enqueue and one route handler to do the work. Works from Vercel, Cloudflare, Deno or anything that can receive an HTTP POST.

Know before you commit

Each delivery attempt counts as a message, so a flaky endpoint with retries multiplies your bill. The free tier keeps DLQ and logs for only 3 days and caps message size at 1MB.
