New monitoring generation · Docker & Kubernetes

Your entire stack.
One single container.

Containers, endpoints, SSL certificates, cron jobs, system resources, updates — monitored in seconds. Zero configuration.

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

After — Maintenant

Features

Everything you need.
Nothing more.

Containers

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

Containers

HTTP/TCP Endpoints

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

HTTP/TCP Endpoints

Heartbeats / Cron

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

Heartbeats / Cron

SSL/TLS Certificates

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

SSL/TLS Certificates

System Resources

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

System Resources

Update Intelligence

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

Update Intelligence

Unified Alerts

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

Unified Alerts

Status Page

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

Status Page

REST API + MCP

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

REST API + MCP

Network Security Insights

Detect open ports, exposed services, and unencrypted endpoints across your stack. Get actionable findings without external scanners.

Network Security Insights

Unified Security Posture

Pro Consolidated security view combining CVEs, exposed ports, certificate issues, and misconfigurations. Risk scoring and remediation priorities.

Unified Security Posture

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.
