We publish a substitute list only where a record says what kind of product it is. heap.io's does not yet, so this page names none. The Analytics category lists every offer we track alongside it.
Current heap.io Situation
Risk Level:source unconfirmed
Why: When we read the page we cite for heap.io on 2026-10-23, we found a change we could not reconcile with the terms we publish for it, and we have read it again since, on 2026-11-13, without confirming them. We are not publishing a stability judgement for it until that is fixed.
