Feder and Piwik PRO: keep Piwik PRO, check the numbers you run on.
No, Feder is not a replacement for Piwik PRO. Keep Piwik PRO. 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 Piwik PRO?
No. Piwik PRO is a privacy-focused analytics platform, with tag management and data activation, built for highly regulated industries. 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 Piwik PRO?
They do different jobs, so one does not stand in for the other. Keep Piwik PRO 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.
