Summary

QStash is Upstash's serverless HTTP task queue for when you need reliable async calls, scheduled jobs, or webhook delivery without running infrastructure. Send messages to public HTTPS endpoints with built-in retries, schedule cron jobs that hit your APIs, or fan out events to multiple services. The signature verification is non-negotiable since your endpoints are public URLs, and the skill hammers this home hard with a critical sharp edge warning. Good fit for Next.js apps, Cloudflare Workers, or any serverless setup where you'd otherwise reach for a managed queue but everything already speaks HTTP. Delays are free, deduplication is included, and callbacks tell you when delivery succeeds or fails.
