In their own words
Checkmk
Checkmk monitors cloud, hybrid, and data center infrastructure, including containers and networks. For web, mail, and database servers, it combines more than 2,000 smart checks with automatic discovery and network mapping. Monitoring can use native agents for Windows, Linux, and other systems, agentless SNMP and TCP/UDP checks, or API-based checks over HTTP/XML, SSH, or TELNET. Cloud coverage includes AWS, Azure, and Google Cloud Platform, with automatic component detection and Quick Setup. One instance can monitor thousands of servers, while distributed monitoring supports horizontal scaling. Community includes more than 2,000 integrations and is intended for smaller environments, scaling to approximately 100 hosts. The software can run on customer hardware or virtualized infrastructure, with Linux distribution packages, Docker, and a Virtual Appliance. The Community plan is free forever and includes community support. The pricing note lists paid plans from €190/mo (annual) and a 30-day trial. Other listed plan prices use USD: Pro is $275 a month, Cloud is $290 a month, and Ultimate is $400 a month. Platforms include API, Linux, macOS, self-hosted, web, and Windows.
Maintenant
Maintenant is a self-hosted, single-container dashboard for monitoring Docker and Kubernetes infrastructure. It tracks containers, HTTP and TCP endpoints, cron heartbeats, TLS certificates, and CPU, memory, network, and disk metrics. It can discover containers automatically, monitor health and restart loops, and stream logs. Update Intelligence checks OCI registries for image digest changes, while security insights identify exposed ports and risky configurations. The software uses SQLite by default, can be configured to use PostgreSQL, and does not require a separate datastore service. A REST API, real-time SSE streams, and an MCP server connect it to other systems and AI assistants. Community includes webhook and Discord alerts; paid editions add email and Telegram, and Pro adds Slack, Teams, and escalation policies. Community is free forever. Personal costs €149, paid once, including one year of updates; further updates cost 59 € incl. VAT per year. Pro costs €29 a month excluding VAT, or 290 € excluding VAT per year. There is no built-in authentication, so the dashboard and admin API need protection through a reverse proxy and authentication middleware.
