Pier

A macOS menu-bar app that looks inside every server — the Docker Compose stacks running there, their health, host trends and live logs — and tells you the moment an image is out of date so you can update it in one click — with every unhealthy container gathered into one issue center. All over the SSH you already use.

Import once, stay in sync. Pull in DigitalOcean and Hetzner — Pier adds new droplets and drops destroyed ones every hour. Agentless and read-only by default; no keys or passwords stored.

Drill in

Expand a server to see every container.

Compose stacks, per-container state and CPU, ports, and a red flag the moment something exits — like postgres here.

Logs, inspect, tunnels — without leaving the menu bar.

Pier streaming a container's logs inline, with an active SSH port-forward tunnel on a container port — Fold a container’s live logs open under its row — no terminal. Click a port to open an SSH tunnel to `localhost`; the blue badge means a newer image is out, one click updates it.

Pier container inspect detail: restart count, healthcheck output, image, memory limit, mounts and redacted env — Click any container to inspect it — restart count, last healthcheck output, image, memory limit, mounts and environment, with secret values redacted.

Pier settings: refresh interval, metrics display, image-update checks, launch at login, read-only connection — Tune refresh, parallelism, metrics, image-update checks, launch-at-login, a hardened read-only SSH key, and a one-click support bundle. Read-only until you opt in.

FAQ

Small details.

What is Pier for?

Pier gives you one glanceable place for every server you run — what Docker stacks are deployed, whether they're healthy, host load/disk, and live logs — without opening a terminal or a heavy dashboard.

How does it connect?

Over your existing SSH (the same ~/.ssh config and agent you already use). Pier stores no SSH keys and no passwords, and is read-only by default — container restart/stop/start is an opt-in setting.

Do I need to enter my key after updates?

No. Pier saves the license in the macOS Keychain. Updates keep using the same saved license on that Mac.

Are future updates included?

Yes. One Pier license includes all future updates in perpetuity for the Mac activated by that license.

Know what's running, without opening a terminal.

One license activates one Mac and includes every future update. Paste your key once — Pier remembers it.
