Ports, with a face.
Every listening socket mapped to the app that owns it — and whether it’s bound to localhost or your whole network.

New in 0.1 — Ask your Mac in plain English
Every process.
Every port. Accounted for.
HyperMonitor is a native Mac app that shows what’s running, what’s listening, and what looks out of place — then explains it, without anything leaving your machine.

Overview
Four lenses.
One honest picture of your Mac.
Processes, ports, launch agents and findings — read straight from the kernel with libproc, refreshed live, and laid out the way a Mac app should be.
Triage that tells you why.
Ten plain-spoken rules flag unsigned listeners, binaries swapped while running and freshly added launch jobs — ranked critical, medium or low.
- Unsigned binary listening on all interfaceshelperd · TCP 0.0.0.0:7000Critical
- Executable changed while the process was runningUpdater · /Applications/Foo.appMedium
- Ad-hoc signature, no Team IDmy-cli · ~/bin/my-cliLow
Launch agents, uncovered.
Every agent and daemon that starts with your Mac — user or system — with the plist, the program and the process it spawned.

Explained on-device.
Not sure what mDNSResponder is? HyperMonitor asks Apple’s on-device model and answers in a sentence. Nothing is uploaded.
mDNSResponder
Apple’s Bonjour service. It resolves names like printer.local and is expected to listen on UDP 5353.
Ask your Mac.
“What’s using port 8000?” HyperMonitor hands a snapshot to the CLI you already use — and shows you exactly what goes out first.
Why is Docker listening on 2375?
That’s the Docker API without TLS. Safe on localhost, risky if bound to 0.0.0.0.
Private by design.
Your Mac stays your business.
HyperMonitor reads what macOS already knows. It doesn’t phone home, doesn’t need an account, and doesn’t install a kernel extension.
No telemetry
No analytics, no crash reporters, no network calls of its own. Check HyperMonitor’s own row — it isn’t listening on anything.
On-device answers
Explanations come from Apple’s on-device model. The process, the path, the answer — none of it leaves the Mac.
You see it before it’s sent
Ask uses the CLI already on your Mac, and only after you’ve reviewed the snapshot it will receive.
Light as a feather
A native SwiftUI app built on libproc. No agents, no extensions, no background daemons.

Questions
What happens after the trial?
The trial lasts 14 days with every feature and no signup or card. When it ends, live monitoring stops, but your history stays readable. Buy a license any time to pick up where you left off.
Is it really open source?
Yes. The source stays open on GitHub and building it yourself stays free. Buying gets you the signed and notarized build, automatic updates, the Homebrew cask and support.
How many Macs can I use it on?
A Personal license covers 2 of your own Macs; the Team 5-pack covers 5 seats. Limits are on the honor system — no activation servers.
Can I get a refund?
Yes. Refunds are available for 30 days through Lemon Squeezy.
Does the AI cost extra?
No. Ask and Explain use the Claude CLI already on your Mac, under your own subscription. There's nothing extra to pay us.
What about 2.0?
Your license includes every 1.x update. When 2.0 arrives, upgrades will be about 50% off, and your 1.x version keeps working either way.
