Compare Checkmk's free Community edition and paid Pro, Ultimate, and Cloud tiers, pricing from €190/month, and its 2,000+ integrations for hybrid IT monitoring.
Checkmk traces back to 2007, when Mathias Kettner founded the company in Munich, Germany, to develop what was then called Check_MK, a monitoring tool built on the open-source Nagios core and first released under the GPL in 2009. The company was renamed tribe29 in 2019 (alongside the Checkmk product rebrand) and became Checkmk GmbH in 2023, remaining headquartered in Munich with offices in Atlanta and Minneapolis.
Today Checkmk is used by more than 5,000 commercial customers plus a large open-source user base to monitor hybrid IT environments spanning networks, servers, databases, cloud workloads, Kubernetes, applications, and user experience, with over 2,000 pre-built integrations available out of the box.
Checkmk automatically discovers services across an environment and provides dashboards, alerting, and notification rules for infrastructure and application monitoring. Higher editions add distributed monitoring for large multi-site environments, advanced automation, and deeper cloud-native and Kubernetes integrations.
The Ultimate and Cloud editions extend the platform with full-stack observability and security/compliance-oriented features, while the free Community edition retains the core monitoring engine and plugin ecosystem for smaller deployments.
Checkmk Community is free and open source under the GPL, suited to environments of roughly up to 100 hosts with community-only support. Paid self-hosted editions start with Pro at around €190/month (billed annually) and Ultimate at around €275/month (billed annually), both scaling to much larger environments with professional support SLAs.
Checkmk Cloud, the SaaS edition hosted on AWS, starts at around €240/month (billed annually) with a 99.5% availability guarantee. Commercial pricing is based on monitored services, custom application metrics, and synthetic tests rather than a strict per-host fee.
