Maintenant vs Sematext Container Monitoring

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.

Sematext Container Monitoring provides visibility into containerized and distributed infrastructure. Its lightweight Sematext Agent runs as a container and gathers host and container metrics, logs, and events. Deployment options include Kubernetes DaemonSet, Docker Swarm, Rancher, Nomad, Portainer, Mesos, DC/OS, or a docker run command. The service can discover applications in containers and start monitoring agents automatically. Dashboards and alert rules are supplied for collected data, while a shared dashboard lets you filter metrics, logs, and events together. Troubleshooting views show hot containers, top processes, and Kubernetes details such as replica counts and pod restarts. Supported environments include Docker platforms, Kubernetes services, AWS ECS and EKS, AKS, GKE, OpenShift, and others. The product lists more than 100 integrations. A free plan and 14-day trial are available; the trial requires no credit card. Basic Infra Monitoring starts at $2.80 a month, with metered usage.
