Upstash QStash

Add serverless messaging and scheduling with Upstash QStash. Covers HTTP-based message queues, delayed and scheduled delivery, cron jobs, retries with backoff, dead-letter handling, and signature verification for reliable jobs on serverless and edge.

This skill helps you offload background work with Upstash QStash, an HTTP-first message queue for serverless. It publishes messages to endpoints, schedules delayed and recurring cron deliveries, configures retries and dead-letter queues, verifies request signatures, and builds fan-out and callback flows that survive stateless, scale-to-zero runtimes.

When to use

Use when adding background jobs or scheduling on serverless with Upstash QStash — HTTP message queues, delayed/scheduled delivery, cron, retries, dead-letter queues, or signature verification.
