There's a free plan; paid tiers are quoted.
Nagios XI starts at $2,595 one-time for Standard Edition with a 100-node license; Enterprise starts at $4,690 for the same tier. Both prices include the first year of Maintenance & Support, but renewal prices are not published. There is also a Free Edition capped at seven nodes or 100 services, whichever comes first. Monthly and annual paid pricing is not published, so compare the node tier—not a monthly rate—before budgeting.

Support renewals

Enterprise add-on
The Standard Edition Enterprise add-on is listed at $2,095. Check whether it covers the features your team needs before choosing a tier.

03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Small monitoring environments | Free Edition | Costs $0, but is capped at seven nodes or 100 services, whichever comes first. |
| Teams buying node-tier licenses | Standard Edition | Starts at $2,595 one-time for 100 nodes and includes unlimited services per licensed node. |

04Is Nagios XI worth the money?
Nagios XI has broad monitoring coverage across servers, networks, databases, applications and cloud platforms, and its paid licenses include unlimited services per licensed node. But the free cap is tight, 100-node paid entry costs thousands upfront, and support renewals are unknown. We would shortlist it when Nagios’s monitoring model and one-time licensing fit the team’s needs; otherwise, compare migration scope and total ongoing support cost before committing.
