Checkmk has a free Community edition, while the published pricing information lists Pro from €190/month and Ultimate from €275/month, both billed annually; Cloud is listed at €240/month. Paid prices are shown in euros, not USD. Community is capped at about 100 hosts; Pro and Ultimate list 100–1,000+ hosts, with roughly 3,000 services at 100 hosts. Synthetic Monitoring shows €0/month but is only available with Pro or Ultimate.

The published price grid lists Pro and Ultimate in euros, and Cloud at €240/month; USD equivalents are not published.

03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Small infrastructures or personal projects | Community | It is free forever and includes 2,000+ integrations, community support, and up to about 100 hosts. |
| Growing data center teams | Pro | It starts at €190/month billed annually and lists 100–1,000+ monitored hosts with professional support. |
| Hybrid and cloud-native teams | Ultimate | It starts at €275/month billed annually and lists 100–1,000+ monitored hosts, plus professional support. |
04Is Checkmk worth the money?
Checkmk's strongest price case is a free entry tier with 2,000+ integrations and broad infrastructure coverage, plus paid options for larger or SaaS deployments. The catch is that paid prices are euro-denominated, Pro and Ultimate require annual billing, and the host and service figures make capacity part of the buying decision. We would shortlist it when infrastructure monitoring is the main need; the published pricing does not let us compare paid costs directly in USD.

What are the default username and password for Checkmk?
The published Checkmk pricing and product information does not state a default username or password. We would not assume credentials from another version or installation method. Check the setup instructions for the specific edition and deployment you are configuring.
What is the current version of Checkmk?
The published materials do not publish Checkmk's current version, so we can't verify a version number here. Check the vendor's download or release information for the latest version and its edition-specific details.

The published product and pricing information does not say whether Checkmk is based on Nagios. It describes Checkmk as a monitoring platform with open-source and paid editions, but does not identify its underlying software lineage.
