Feder and Fathom Analytics: keep Fathom Analytics, check the numbers you run on.
No, Feder is not a replacement for Fathom Analytics. Keep Fathom Analytics. 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 Fathom Analytics?
No. Fathom is a privacy-focused website analytics tool, offered as a simple, cookie-free alternative to Google Analytics. 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 Fathom Analytics?
They do different jobs, so one does not stand in for the other. Keep Fathom Analytics 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.
What does Fathom Analytics do better?
Fathom keeps a site's key numbers on a single, easy-to-read page.
In Fathom Analytics's words:
You get one page of useful data, not thousands of reports to hunt through.
