There's a free plan; paid tiers are quoted.
Checkmk Community is free and open source, with the vendor positioning it for smaller infrastructures and roughly 100 hosts. Paid plans add support, automation, distributed monitoring, and hybrid or cloud-focused features. Pro starts at €190 per month billed annually, Ultimate at €275 per month billed annually, and Cloud lists €240 per month. Pricing is described as host- and service-based, so production costs depend on the estate you monitor. The site displays these amounts in euros; it does not show USD prices.

02What the plan grid doesn't tell you
Host and service growth
Checkmk describes pricing as host- and service-based. Pro and Ultimate show 100–1,000+ hosts and about 3,000 services at 100 hosts; ask how growth changes your quote.
Cloud user cap
Cloud lists 20 user accounts and up to 50,000 services. Confirm the price and options if your team needs more accounts or services.
Synthetic test limits
Synthetic Monitoring lists three free tests and shows up to 1,000 tests; it is only available with Pro and Ultimate. Ask how paid test volume is billed.
Self-hosting operations
Community can be self-hosted, but teams need to operate the monitoring infrastructure. Include that infrastructure and maintenance work in the cost comparison.
03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Personal project or small estate | Community | Free and open source, with automated discovery and roughly 100 hosts as the stated scale. |
| Growing data center | Pro | Starts at €190/month billed annually and adds distributed monitoring, automation, and 8×5 professional support. |
| Hybrid estate using managed SaaS | Cloud | Lists €240/month, up to 50,000 services, 20 user accounts, and a 99.5% uptime SLA. |
04Is Checkmk worth the money?
The free Community edition is a practical starting point for small infrastructures and personal projects, especially if your team can operate Checkmk on premises. Pro and Ultimate make sense when distributed monitoring, automation, support, or hybrid-cloud features justify an annual commitment. Cloud is the simpler managed option, but its listed 20-user and 50,000-service limits need to fit your estate. Ask Checkmk for a quote that covers growth, extra users, synthetic-test volume, and any required support.
