Maintenant review
A broad, open-source monitoring stack with a free tier and paid security features.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Maintenant is a self-hosted monitoring product for Docker and Kubernetes environments, delivered as a single container or binary. It is aimed at individuals, teams, and infrastructure operators who need visibility across container health, resource usage, logs, image updates, endpoints, certificates, and public status pages. Automatic discovery covers Docker, Kubernetes, and Docker Swarm, while the platform supports Linux amd64/arm64, macOS, WSL2, Windows, web access, an API, and self-hosted deployment. Its open-source Community edition also makes it suitable for smaller environments that want core monitoring without a paid plan.
Pricing is split across three editions. Community is free forever and includes container auto-discovery, metrics and a status page, an alert engine, webhook and Discord routing, and the full API. Personal costs €149 one-time and adds support for up to 20 hosts, email alerts, CVE tracking, risk scoring, security posture monitoring, and 30 days of resource history. Pro costs €29 per month or €290 per year, with unlimited hosts, Slack and Microsoft Teams alerts, escalation policies, maintenance windows, status-page subscribers and branding, and support. A 14-day free trial is also available. Buyers should compare the host limit and alert-routing needs carefully before choosing a paid tier.
Maintenant’s main strength is breadth within container operations: it combines lifecycle and health checks with CPU, memory, network I/O, and disk I/O metrics; threshold alerts; real-time stdout and stderr logs; OCI image update detection; HTTP and TCP endpoint monitoring; and SSL/TLS certificate monitoring. REST API, SSE streams, and an MCP server extend its integration options, alongside Coolify, Dokploy, Unraid, and Synology support. It suits operators who want one self-hosted product spanning monitoring, incident communication, and selected security signals. Teams needing unlimited hosts, collaborative alerting, or vendor support should choose Pro; smaller deployments can remain on Community.
