What is maintenant?
maintenant monitors Docker, Docker Swarm, and Kubernetes infrastructure from a single Go binary or container. It auto-discovers containers, health checks, restart loops, and live logs without configuration. It watches HTTP/TCP endpoints declared as Docker labels, TLS certificate expiry, cron job heartbeats, host CPU/memory/network/disk metrics, image updates with CVE enrichment, and network security exposure. Alerts route to multiple channels with escalation policies. A built-in MCP server lets AI agents investigate alerts read-only. The Community edition is free forever for one host; Personal (€149 once) adds multi-host agents, CVEs, and email/Telegram alerts; Pro (€29/mo) adds unlimited hosts, Slack/Teams, escalation, and maintenance windows. Install via Docker Compose, Kubernetes manifests, a static binary for bare Linux, or cloud-init for major cloud providers. Core is Apache-2.0 licensed; commercial features use a separate source-available license.
