Feder and Amplitude: keep Amplitude, check the numbers you run on.
No, Feder is not a replacement for Amplitude. Keep Amplitude. 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 Amplitude?
No. Amplitude is a product analytics platform that brings AI into each step of building digital products, from analytics to feedback to code. 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 Amplitude?
They do different jobs, so one does not stand in for the other. Keep Amplitude 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.

How does Feder work with Amplitude?
- Feder has no connection to Amplitude today, so it reads nothing from it.
- The two can run side by side: Amplitude keeps doing its job, and Feder checks the numbers your other tools record against your own history.
- Feder only reads. It never changes anything in a connected app.
What should I ask about my Amplitude 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?
