Is PRTG worth the price?

75/100

PRTG offers a genuinely useful free tier, 100 sensors covering roughly 10 devices is enough for a small office or homelab.

Paid plans start at $179/month (annual) for 500 sensors and scale to $1,492/month for 10,000 sensors. The per-sensor pricing model is both a strength and a trap: each device typically needs 5-10 sensors (CPU, memory, disk, network, services), so a 50-device network easily requires 250-500 sensors.

At $179/month for 500 sensors, PRTG is competitive with Datadog for small deployments, but Datadog per-host pricing becomes cheaper at scale. The 30-day trial with unlimited sensors lets you accurately size your needs before committing.

No perpetual licensing exists anymore, it is subscription-only.

Hidden Costs & Gotchas

Sensor count can balloon quickly, each device typically needs 5-10 sensors for meaningful monitoring. A 100-device network may need 500-1,000 sensors, pushing you into the $325-675/month range.

All prices are subscription-only (paid annually). There is no monthly billing option, you commit to a full year upfront. A PRTG 2500 license is $8,100/year paid at once.

PRTG Enterprise Monitor (for 1,000+ devices) is a separate product with custom pricing that is not listed on the standard pricing page, expect significantly higher costs.

Remote probes for monitoring distributed locations require additional sensor allocation from your license, there is no separate probe fee, but it eats into your sensor budget.

SNMP, WMI, and flow sensors each count separately against your limit. A single switch with SNMP traffic, bandwidth, and port sensors can consume 10-30 sensors alone.

Email/SMS notifications are included, but advanced alerting integrations (PagerDuty, Slack webhooks) require configuration effort that may need professional services.

Database monitoring, cloud monitoring (AWS/Azure), and advanced flow analysis sensors are included but consume sensors faster than basic ping/SNMP checks.

How PRTG Compares to Competitors

Datadog is the main cloud-native alternative at $18/host/month for infrastructure monitoring, cheaper per-device than PRTG for large deployments but expensive when you add APM, logs, and synthetics. Zabbix is the strongest free alternative with enterprise-grade capabilities, but demands serious Linux and configuration expertise. Nagios XI offers perpetual licensing (one-time $3,495 for 500 nodes) that PRTG no longer provides, attractive if you want to avoid subscriptions. SolarWinds NPM competes directly with PRTG in the traditional network monitoring space with similar pricing. For pure uptime monitoring (not full network monitoring), Uptime Kuma (free, self-hosted) or Better Stack ($29/month) are dramatically cheaper.

How PRTG's pricing compares

At $150/mo, PRTG is the most premium of its 2 direct competitors.
