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
- Local-first monitoring
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.

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
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.
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
Simple flow, fast read
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.
Watch
LeakBar samples same-user processes, builds baselines, and ranks growth patterns quietly in the background.
Act
When something looks wrong, the menu shows the score, the reasons, and the next safe action: inspect, probe, recover, restart, ignore, or export.
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.
