Feder and UptimeRobot: keep UptimeRobot, check the numbers you run on.
No, Feder is not a replacement for UptimeRobot. Keep UptimeRobot. 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 UptimeRobot?
No. UptimeRobot is an uptime monitoring service that continuously checks websites, APIs and other endpoints. 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 UptimeRobot?
They do different jobs, so one does not stand in for the other. Keep UptimeRobot 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 UptimeRobot do better?
UptimeRobot does not mark a monitor down on a single failed check: it re-checks first, which helps keep false alarms down.
In UptimeRobot's words:
A single failed check does not immediately mark a monitor as Down.
