Once the 30-day trial of a self-hosted Checkmk edition ends, you can either license your site with a paid subscription or continue using it for free as long as you want. The free version allows up to 750 monitored services on a single site and does not support distributed monitoring.
For Checkmk Cloud (SaaS), you must activate a paid subscription before the 30-day trial period ends to keep your monitoring active. Otherwise, your trial instance and its configuration will be automatically deleted
You can purchase a Checkmk license online or by requesting a quote from our sales team. Once you have your subscription, you simply enter your license credentials directly into your existing trial site.
The Checkmk server is not supported on Windows. However, you can monitor Windows hosts using the Checkmk agent.
For the server itself, we suggest starting a Checkmk Cloud trial — our SaaS edition that runs entirely on our cloud infrastructure.
The easiest way to get started with a PoC is to start a trial, create a new site, and use the 30-day trial period. If you need more than 30 days to build your PoC, please contact our sales team, and we will be happy to issue an extended PoC license.
