Looking for a PRTG Alternative?

PRTG has been a network monitoring staple for decades. But its Windows-only server, sensor-based pricing, and desktop-era interface feel dated in a cloud-native world. FiveNines runs on Linux, prices per host, and deploys in 2 minutes.

Linux-native, no Windows server required

PRTG's core server runs on Windows only. Remote probes support Linux, but the central server doesn't. FiveNines is built for Linux environments from the ground up.

Per-host pricing, not per-sensor

PRTG charges by sensor count. A single server can consume 10-20 sensors easily. FiveNines charges per host - all metrics for that host are included regardless of how many you track.

2-minute agent install

PRTG setup involves installing a Windows server, configuring probes, and adding sensors one by one. FiveNines: run one install script, metrics flow in 30 seconds.

Why teams switch from PRTG

PRTG's sensor-based pricing means a single server can eat 10-20 sensors. The Windows-only core server and desktop-era interface feel increasingly out of place in Linux and cloud environments. Teams switch when they want per-host pricing, a modern UI, and a 2-minute agent install instead of a Windows server deployment.

Frequently Asked Questions

What's the main difference between FiveNines and PRTG?
FiveNines is cloud-native and Linux-first with per-host pricing. PRTG requires a Windows server for the core installation and charges per sensor (a single server can consume 10-20 sensors). FiveNines includes all metrics for a host in one price.
Does FiveNines support Windows servers like PRTG?
FiveNines focuses on Linux server monitoring. If your infrastructure is primarily Windows-based, PRTG is a better fit. If you run Linux servers and need SNMP monitoring for network devices, FiveNines covers both.
Can FiveNines replace PRTG for network monitoring?
For SNMP monitoring of switches, routers, and firewalls alongside Linux server monitoring, yes. PRTG offers more sensor types (WMI, NetFlow, packet sniffing) that FiveNines doesn't cover.
