Feder and Heap: keep Heap, check the numbers you run on.
No, Feder is not a replacement for Heap. Keep Heap. Feder does a different job beside it: it reads what your connected apps recorded and compares each number with your own history, so you know when one cannot be trusted.
Why would I need this?
Because the question is not what the number is. It is whether you can trust it.
Is Feder an alternative to Heap?
No. Heap is a digital analytics tool that automatically captures every user interaction on a website or app, with session replay built in. Feder does a different job: it watches the numbers your tools record and says when one cannot be trusted. Nothing here asks you to switch.
Do I need Feder if I have Heap?
They do different jobs, so one does not stand in for the other. Keep Heap for the job it does. Feder's job is to say when a number your tools record has gone quiet or moved outside your own history.

- Feder only reads. It never changes anything in a connected app.
What should I ask about my Heap setup?
- Which numbers on my dashboard are counted at the source, and which are modeled or estimated?
- If this number stopped counting tomorrow, who would notice, and when?
- What does a normal week look like for this number, in my own history?
