“We tried PRTG, Zabbix, and Checkmk. PRTG got too expensive at scale, Zabbix was complex to manage, Checkmk's interface didn't fit. Fivenines was easier to deploy, sustainable at our scale, and the product keeps actively improving.”

Quick Comparison

The rows that usually decide whether PRTG stays in the stack or Fivenines replaces it.

Feature	P PRTG	Fivenines
Deployment	Windows core or Hosted Monitor; local probes	Hosted dashboard; local agent for SNMP
Linux monitoring	Linux targets and multi-platform probes	Linux agent; net-snmp tools for device polling
SNMP polling	v1, v2c and v3	v2c and v3
Device setup	Auto-discovery and device templates	Explicit device IP, credentials and polling host
SNMP traps	SNMP Trap Receiver sensor; check probe compatibility
Billing model	Sensor-based tiers	Shared monitor quota across servers, devices, uptime and cron
Starting price	Free up to 100 sensors; $200/mo (PRTG 500, billed annually)	€19/mo

Why teams consider Fivenines instead of PRTG

One monitor quota, not sensors

A server, a network device, an uptime check or a cron task each counts as one monitor. All of a server's metrics and a device's interface counters are included.
Servers and switches side by side

Server metrics, service integrations and interface counters share one dashboard, so a saturated uplink and the servers behind it are one view.
Incidents built in

Device, server, uptime and cron alerts open incidents with a timeline and notify your channels. Servers, uptime checks and cron jobs can also appear on a public status page.

Deep dive

PRTG on Linux: core server and probes are different

PRTG Network Monitor uses a Windows core server, but that does not mean all monitored hosts or probes must run Windows. Paessler offers multi-platform probes for Linux and PRTG Hosted Monitor for a hosted core.

With Fivenines, you install the server agent where you need host metrics. For SNMP devices, assign a polling host with that agent and the net-snmp client tools. Fivenines manages the dashboard and storage; you manage the local collector and device access.

When PRTG might be the better fit

Keep PRTG when required sensor types, automatic device discovery or SNMP trap reception are central to your operations. Fivenines focuses on configured-device polling and server monitoring; it does not reproduce the PRTG sensor catalog.

Fivenines is the better fit when server metrics and interface-level SNMP polling cover what you need, and you want them in one hosted account with a shared monitor quota.

Frequently Asked Questions

Is Fivenines a PRTG alternative for Linux? +

Yes, when you want hosted monitoring for Linux server metrics and SNMP v2c/v3 devices. Fivenines uses an agent on your network with net-snmp client tools. PRTG also monitors Linux: its self-hosted core requires Windows, but multi-platform probes run on Linux and work with PRTG Hosted Monitor.

Is Fivenines an open-source PRTG alternative? +

The Fivenines agent is open source. The monitoring platform is a paid hosted service with a 14-day trial, not a self-hosted open-source PRTG replacement. If operating your own open-source monitoring stack is required, evaluate that requirement separately.

How does pricing differ from PRTG sensors? +

PRTG licenses by sensors. Fivenines uses a shared monitor quota: one server, one network device, one uptime check or one cron task each consumes one monitor. The SNMP polling host counts as a server monitor too; the interface counters of a device do not each use another monitor. Compare your required coverage and current plans rather than treating a sensor as a device.

Can I move all my PRTG sensors to Fivenines? +

There is no PRTG sensor or historical-data import. Start with one server and one SNMP device, compare the required metrics and alerts, and run both tools in parallel. Keep PRTG for sensor types or trap reception that Fivenines does not cover.
