Flotilla · by melonfleet

Apple’s containers, with a window.

Apple shipped container for macOS and left it on the command line. Flotilla is the native app on top: containers, images, volumes, networks and the virtual machines they run inside — plus a real terminal in every container. Free, no account, no telemetry.

Flotilla's dashboard: memory-pressure graph over five minutes, disk and network throughput charts, and a table of every running container with CPU, memory and I/O. — **Dashboard.** What the whole Mac is doing — pressure over five minutes, disk and network throughput, and every container’s CPU, memory and I/O in one table.

Flotilla's container list: one row per container with live CPU and memory, published ports, IP address, and start, stop and delete controls. — **Containers.** Live CPU and memory per container, published ports, addresses, and start/stop/delete on the row. Switch to cards if you prefer.

Flotilla's terminal tab: a shell open inside the running nginx container, showing its version, a passing configuration test, the nginx master and worker processes, and a live HTTP 200 response. — **Terminal.** A real shell inside any running container or machine — test a config, read the process table, ask it for a page, without leaving the window.

Flotilla's log view: a single combined feed of log lines from several containers, each tagged with its source, above a filter field. — **Logs.** Every source in one feed, each line tagged with where it came from, filterable by name or text. No tab-hopping between containers.

Flotilla's machines view: the virtual machines containers run inside, with CPU and memory allocation and controls to create, resize, start, stop and open a shell. — **Machines.** The virtual machines your containers actually run inside — create, resize, start, stop, and open a shell in one.

Requirements & install Why melonfleet

Not released yet · signed, notarised 0.9.0 in testing

What it does

Everything goes through Apple’s own `container` CLI.

Flotilla shows the exact command it used, so nothing happens that you could not have typed yourself.

container run -d --name api -p 8080:80 nginx:latest

Run and watch

Start, stop and delete containers, and see live stats and logs while they run.

Shell straight in

A real terminal in any container or machine, without leaving the window.

Everything else too

Images, volumes, networks and the virtual machines your containers run inside.

Requirements & install

Two things, and nothing else.

macOS 26 or later

On Apple silicon.

Apple’s `container` CLI

Installed separately from apple/container. Flotilla drives that tool; it does not bundle or replace it.

Nothing else

No account, no telemetry. Signed with a Developer ID and notarised by Apple.

Flotilla is not released yet. There is a signed, notarised 0.9.0 for testing; 1.0 follows. A download link appears here when the repository is public and a release exists.

More fruit on the way.

Flotilla is the first thing melonfleet has put out. There is more growing — quietly, and only announced when it is actually finished. Nothing to sign up for.
