# Cetacean

Cetacean is a real-time observability and management dashboard for Docker Swarm mode clusters. It reads your
cluster through the Docker socket and keeps the page current on its own—there's nothing to poll and nothing to
refresh.

Every resource in your swarm—nodes, services, tasks, stacks, configs, secrets, networks, volumes—is browsable,
cross-referenced and editable in place. The same data is available over a web API and to AI agents over an
embedded MCP server. Add Prometheus and you get CPU and memory charts, capacity bars, and sizing
recommendations.
