macOS Menu Bar Utility

Find the process making your Mac feel wrong.

LeakBar turns memory growth, baselines, release behavior, and Mac pressure into a short suspect list. Start the registered 14-day in-app trial by entering an email in the setup wizard; process data stays on your Mac unless you export it.

  • 14-day in-app trial
  • Trial lifecycle emails, no payment
  • Current release: 1.2.6

Release

Signed DMG. Install once; in-app updates take over.

Licensing

Trial first. Purchase once when it earns a spot.

Evidence

Suspicion is passive; probe, export, recover, and restart stay explicit.

Licensing

Register the 14-day trial in setup with an email. Trial lifecycle emails are sent, process data stays local, and purchase is a one-time perpetual license.

Secondary bundle

Support

Recover a license or get purchase help

Use the checkout email for private recovery lookup. The public form always returns the same generic recovery status.

License recovery

Enter the checkout email. If a matching record and delivery path exist, recovery delivery is attempted without exposing lookup results.

Support zone

What support can verify without adding an account system.

  • Checkout email anchors private lookup
  • R2 stores license records and delivery logs
  • Generic public status prevents email enumeration
  • Download page publishes the DMG, redirect, and SHA-256
Core Features

Designed around triage clarity, not dashboard noise.

Guardian mode

Menu bar scoring filters startup, cache, plateau, and normal churn patterns.

Developer probe

Wrap a command with leakbar wrap -- cargo run and capture leaks and vmmap artifacts when suspicion crosses the line.

Shipped app flow

Signed SwiftUI menu bar app with built-in updates after install.

Readable scoring

Reasons name growth, idle retention, baselines, and pressure instead of hiding behind a score.

Recovery and restart feedback

Recover and restart actions report explicit completion state.

Evidence Model

Honest about what it knows

Passive suspicion is useful; probe capture is stronger evidence.

What passive mode can tell you

  • Leak suspicion
  • Probable leak
  • Critical runaway
  • Cache bloat
  • Idle retention
  • Restart candidate

What requires probe mode

  • Confirmed leak with stack traces
  • Allocation site identification
  • Malloc history
  • Wrapped-session evidence
Lifecycle

Simple flow, fast read

1

Install

Download the signed DMG, move LeakBar.app into Applications, and launch setup. Monitoring unlocks after you register a trial email or enter a purchased license key.

2

Watch

LeakBar samples same-user processes, builds baselines, and ranks growth patterns quietly in the background.

3

Act

When something looks wrong, the menu shows the score, the reasons, and the next safe action: inspect, probe, recover, restart, ignore, or export.

Privacy

Your data stays on your Mac

LeakBar does not need an account, analytics, or cloud storage. Process data stays in ~/Library/Application Support/LeakBar/ and can be inspected locally.

This website also avoids tracking, cookies, and analytics.
