TarleyNode compared with PRTG Network Monitor.
TarleyNode and PRTG are both self-hosted network monitors priced by sensors. This page sets out how they differ on price and features, so you can judge which fits your network.
Price
Both products count sensors, where one sensor is one check on one device. At the same sensor count, TarleyNode’s list price is about a quarter of PRTG’s, and still well under half with failover added.
| Sensors | PRTG, per year (incl. 1 failover node) | TarleyNode, per year | TarleyNode with HA (3 nodes) |
|---|---|---|---|
| 500 | USD 2,400 | USD 600 | USD 1,080 |
| 1,000 | USD 4,296 | USD 1,050 | USD 1,530 |
| 2,500 | USD 8,904 | USD 2,250 | USD 2,730 |
PRTG is billed monthly at USD 200, 358 and 742 for these tiers, paid yearly. TarleyNode’s high availability costs USD 480 a year and covers three nodes. Even with it, TarleyNode costs less than half of PRTG at every tier. Both offer a free edition with 100 sensors.
PRTG prices are Paessler’s published list prices as of 6 October 2026. Resellers may offer discounts. TarleyNode prices exclude tax.
