maintenant

The all-in-one monitoring dashboard your self-hosted stack deserves.

Drop a single container. Watch everything. Sleep at night.

What is maintenant?

Most self-hosters juggle 3-5 tools to monitor their stack: one for containers, one for uptime, one for certs, one for metrics, and yet another for a status page. maintenant replaces all of them with a single binary, zero external dependencies, and zero configuration to get started.

Deploy one container, and maintenant auto-discovers your entire stack. Docker or Kubernetes — it does not matter.

Key Features

  • Container Monitoring — Zero-config auto-discovery for Docker and Kubernetes. State tracking, health checks, restart loop detection, log streaming.
  • Endpoint Monitoring — HTTP and TCP checks defined as Docker labels. Response times, uptime history, sparklines.
  • Heartbeat & Cron Monitoring — Create a monitor, get a URL, curl from your cron job. Tracks durations, exit codes, missed deadlines.
  • TLS Certificate Monitoring — Auto-detection from HTTPS endpoints. Alerts at 30, 14, 7, 3, and 1 day before expiry. Full chain validation.
  • Resource Metrics — CPU, memory, network I/O, disk I/O per container. Historical charts, alert thresholds, top consumers view.
  • Update Intelligence — OCI registry scanning, digest comparison. Know when your images have updates available.
  • Alert Engine — Unified alerts across all sources. Webhook and Discord channels. Silence rules, exponential backoff.
  • Public Status Page — Component groups, incident management, scheduled maintenance.
  • MCP Server — Expose monitoring data to AI assistants (Claude Code, Cursor) via the Model Context Protocol. 18 tools, stdio and HTTP transports.
