The problem

You're juggling 5 tools.
Or worse, you have nothing.

Uptime Kuma for HTTP, Healthchecks for crons, Grafana+Prometheus for metrics, an SSL checker, and bash scripts. None of them see the full picture.

Before — fragmented monitoring

  • ✕ Uptime Kuma — HTTP checks only
  • ✕ Healthchecks.io — heartbeats only
  • ✕ Grafana + Prometheus + cAdvisor — 3 containers
  • ✕ Separate SSL checker
  • ✕ No unified view
  • ✕ 5 dashboards, 5 configs, 5 maintenances

After — Maintenant

  • ✓ Auto-discovered containers (Docker + K8s)
  • ✓ HTTP/TCP endpoints monitored
  • ✓ Cron jobs and heartbeats tracked
  • ✓ SSL certificates validated automatically
  • ✓ CPU, RAM, network, disk metrics
  • ✓ One container. One dashboard. Everything's here.
Features

Everything you need.
Nothing more.

Containers

Docker and Kubernetes auto-discovery. States, health checks, restart loops, logs. Compose projects grouped automatically.

HTTP/TCP Endpoints

Active probing with latency, status codes, content assertions. Configure via Docker labels — zero YAML files.

Heartbeats / Cron

Unique ping URL per job. Track durations, exit codes, and get alerted when a cron doesn't run.

SSL/TLS Certificates

Automatic detection on your HTTPS endpoints. Expiration alerts at 30, 14, 7, 3, 1 day. Full chain validation.

System Resources

CPU, RAM, network and disk I/O — per container and per host. Real-time charts with configurable threshold alerts.

Update Intelligence

Detects available updates via OCI scan. Compare digests across all your containers. Stop blind docker pull.

Unified Alerts

Webhook and Discord built-in. Pro Slack, Teams, Email, escalation, routing, and custom templates.

Status Page

Real-time public page for your users. Component groups, live SSE updates. Pro Incident management, maintenance windows, subscriber notifications.

REST API + MCP

Full API under /api/v1/. Real-time SSE streams. Built-in MCP server to query your infra from an AI assistant.

Installation

Operational in 30 seconds

Deploy

Add Maintenant to your docker-compose.yml. Mount the Docker socket read-only. That's it.

docker compose up -d

Auto-discovery

Maintenant detects your containers, their health checks, Compose projects. On Kubernetes, it detects the runtime automatically.

5 containers discovered

Monitor and alert

Add Docker labels for HTTP/TCP endpoints. Configure your Discord or Slack webhooks. Your stack is under control.
