macOS menu-bar utility

Every port,
process & pulse —
docked.

Pier is a featherweight monitor that lives in your menu bar. See what's listening on every port, which process is hogging the CPU, and your system's vitals — then act on them in one click.

// FOUR PANELS, ONE CLICK AWAY

Your Mac, read like an instrument panel.

Flip between four panels from the menu bar. Look, understand, and act — without ever opening a terminal.

See what's listening

Every TCP & UDP port, the owning process and its app icon, the bound address, and an IPv4·IPv6 tag. A glance tells you what's exposed to the network — and one click ends it.

Find the hog, fast

Top processes ranked live by CPU or memory, with app-aware names and icons. Expand any row for the full command line, path, and parent — then end or force-quit it.

Vitals at a glance

CPU, memory, swap, disk, and live network throughput in one tidy panel — or pin a live number right next to the menu-bar icon and never open the window at all.

Skip the terminal

Start, stop, and restart your Docker / Podman containers and Homebrew services straight from the menu bar. Pier even detects when your docker is really Podman.

// FAQ

Good questions.

Why isn't Pier on the Mac App Store?+

Pier needs to see every process and act on it — listing ports, reading other processes, ending them. The App Store sandbox forbids that. So Pier is distributed directly, signed with a Developer ID and notarized by Apple, so Gatekeeper trusts it.

Does it phone home?+

Your monitoring data never does — ports, processes, and system stats are read on-device and never uploaded. Pier itself goes online only to check for updates (you can turn that off) and to activate and periodically verify your license. No third-party analytics or ad trackers.

Will it slow down my Mac?+

It's built in native SwiftUI and samples only while a panel is open or a menu-bar readout is enabled. Idle CPU rounds to zero — a resource monitor shouldn't be a resource hog.

Which Macs are supported?+

macOS 14 (Sonoma) and later, on both Apple Silicon and Intel.

Can I kill any process?+

You can end any process you own. System processes (owned by root) are flagged and guarded with a confirmation — and ending a launchd-managed daemon will just respawn it, which Pier tells you up front.
