Pure Swift Craftsmanship

Built to Feel Like Native macOS

Engineered ground-up using Swift, SwiftUI, QuartzCore, and AppKit accessibility APIs for instant responsiveness.

Blazingly Fast Performance

Built with 100% native Swift & SwiftUI APIs with under 15MB RAM footprint. MacAltTab opens in microseconds without lagging your Mac.

True Multi-Window Switcher

Unlike macOS default Cmd+Tab which lumps all windows together, MacAltTab previews every individual open window instance across all spaces.

Authentic macOS Glass Blur

Powered by native `NSVisualEffectView` real-time desktop blur shaders with selectable HUD Dark Glass, Popover Frosted, Vibrant, and Sidebar styles.

Floating Traffic Light Actions

Manage windows directly inside the overlay overlay! Press W or click red dot to close windows; press M or click orange dot to minimize.

Auto-Scrolling Marquee Titles

Never lose long file paths or website titles. Focused cards feature automated smooth scrolling marquee headers to view full titles.

Native Preferences & Tuning

Fine-tune card dimensions, layout orientation, hotkey triggers (Option vs Cmd), and grid column limits directly in Menu Bar preferences.

Authentic Glass Optics

Designed for Modern macOS Sequoia

Every layer in MacAltTab is custom-built with vector path masking using QuartzCore `CAShapeLayer` and transparent `NSHostingView` layer hierarchies. Visual effects update in real time with ambient desktop luminescence.

Dynamic window thumbnail generation via `CGWindowList`
Accessibility API (`AXUIElement`) integration for focus control
Support for minimized, hidden, and full-screen windows

Total Privacy & 100% On-Device

We Don't Collect Any Data. Period.

MacAltTab runs 100% locally on your Mac. No network connections, no analytics, no tracking, and zero telemetry. Your window titles, application names, and screenshot previews never leave your device.

🔒

We Don't Get Any Data

No personal data, telemetry, or window contents are ever recorded, collected, or transmitted.

📡

Zero Network Activity

The app operates completely offline with zero outbound HTTP requests or server analytics.

💻

100% On-Device Execution

All window switching, graphics, and hotkey processing remain strictly inside your local macOS system.
