Agentless Docker workspace

Every container.
One workspace.

Whale Watch is a browser-based workspace for observing Docker container resources, logs, and status through widgets you arrange—and operating containers from the same screen.

Resource monitoring stage in Whale Watch — CPU, memory, network I/O, and status in a layout you control

Your workspace

Build each stage around
the work in front of you

Whale Watch reads directly from the Docker Engine API without adding monitoring agents or packages to target containers. Organize tabs and widgets around each task.

Customizable tabbed stages

Save a name, color, grid size, and widget layout for every stage. Move and resize widgets with drag and drop, with automatic collision handling.

Real-time resource views

Combine CPU history, memory, network I/O, and container status widgets for the view you need.

Logs and interactive terminals

Read stdout and stderr logs, then open interactive TTY sessions powered by xterm.js and Docker exec.

Start, stop, and restart

Check container status and run lifecycle controls from the same browser workspace.

Update only what matters

Docker events refresh the container list without fixed polling. On inactive tabs, only pinned widgets continue updating in the background.

Quick start

Start with Docker

The SvelteKit SPA is embedded in a Go application and distributed as one container. Mount the data directory to keep stage and widget settings between updates.
