We publish a substitute list only where a record says what kind of product it is. QStash's does not yet, so this page names none. The Messaging category lists every offer we track alongside it.
Current QStash Situation
Risk Level:source unconfirmed
Why: When we last read the page we cite for QStash, on 2026-11-08, we could read no amount, tier or rate on the page. We are not publishing a stability judgement for it until that is fixed.
