In-Depth Overview
What is Amphetamine?
Amphetamine is the most powerful keep-awake utility ever created for macOS. Developed by William Gustafson and distributed free on the Mac App Store, it goes far beyond simple sleep prevention. Amphetamine offers an impressive array of automation features including Triggers that activate based on conditions like connected displays, specific apps running, battery levels, Wi-Fi networks, VPN connections, and even CPU utilization thresholds. The app supports advanced scenarios like keeping your MacBook awake while the lid is closed (clamshell mode), periodic mouse cursor movement to prevent idle detection, and Drive Alive functionality to keep external drives spinning. Despite its power, Amphetamine remains 100% free with no advertisements, in-app purchases, or data tracking. It's the go-to choice for power users who need their Mac to stay awake under complex, conditional circumstances.
What is Caffeine?
Caffeine is the quintessential macOS menu bar utility—tiny, elegant, and purpose-built. Originally created by Tomas Franzén in 2006, the app was revitalized in 2022 by Dominic Rodemer who modernized it for macOS 11+ while preserving its legendary simplicity. Caffeine places a coffee cup icon in your menu bar; click it to toggle sleep prevention on or off. A full cup means your Mac stays awake; an empty cup means normal sleep behavior. Right-click for additional options like setting a duration timer or accessing preferences. At just 4.5MB and open source under the MIT license, Caffeine is the perfect tool for users who want zero friction and immediate results. It requires macOS 11 (Big Sur) or later and runs natively on Apple Silicon. For presentations, downloads, or preventing screen dimming during reading, Caffeine delivers exactly what you need with nothing you don't.
Detailed Feature Comparison
Basic Sleep Prevention
CriticalInstant on/off toggle from menu bar. Can prevent display sleep, system sleep, screen saver, and screen dimming independently. Supports indefinite sessions or timed durations.
Simple click-to-toggle from menu bar. Prevents sleep, display dimming, and screen savers. Empty cup = normal sleep, full cup = stay awake. Supports duration timers via right-click menu.
Verdict: tie
Automation & Triggers
HighAdvanced Triggers system with 15+ conditions: external displays, app running/frontmost, battery charging/level, Wi-Fi network, IP address, VPN, audio output, drive mounted, CPU threshold, idle time, and more.
No automation features. Caffeine is purely manual—click to enable, click to disable. No triggers, conditions, or automatic activation capabilities.
Verdict: amphetamine
Closed-Lid (Clamshell) Support
HighNative support for keeping MacBook awake with lid closed. Can prevent system sleep when built-in display is closed while allowing or preventing external display sleep independently.
No specific closed-lid features. Caffeine prevents sleep system-wide but doesn't offer specialized clamshell mode configuration.
Verdict: amphetamine
Drive Management
MediumDrive Alive feature keeps external drives spinning to prevent unmounting/sleeping. Can also trigger keep-awake sessions when specific drives or volumes are mounted.
No drive-specific features. General sleep prevention may indirectly keep drives awake, but no dedicated functionality.
Verdict: amphetamine
Customizability
MediumExtensive customization: custom menu bar icons, notification sounds, hotkey shortcuts, session end actions, auto-end on low battery, idle lock screen, and periodic cursor movement settings.
Preferences include auto-start on login, auto-activate on start, and default duration. Limited visual customization—one coffee cup icon, one way to display it.
Verdict: amphetamine
Resource Usage & Performance
HighLightweight for its feature set but monitors multiple system conditions when triggers are active. Slightly higher memory footprint due to automation engine. Still efficient on Apple Silicon M3/M4.
Extremely lightweight at 4.5MB. Minimal CPU and memory usage. Designed to be virtually invisible in terms of system resources. Fast startup and instant response.
Verdict: caffeine
AppleScript & Integration
MediumFull AppleScript support for automation workflows. Can be scripted to start/stop sessions, check status, and integrate with other macOS automation tools like Shortcuts and Automator.
No AppleScript support or automation integration. Standalone utility with no external API or scripting capabilities.
Verdict: amphetamine
User Interface & Simplicity
HighClean interface but feature density can be overwhelming. Multiple panels for triggers, preferences, and session control. Excellent for power users but has a learning curve.
The gold standard of simplicity. One icon, one click. No preferences window needed for basic use. The coffee cup metaphor is instantly understandable. Zero learning curve.
Verdict: caffeine

Who Should Choose Which?
1Long software download or system update
For a one-time temporary need, Caffeine's instant toggle is perfect. Click the coffee cup and forget about it—no configuration needed.
2Developer with external monitors and closed MacBook lid
Amphetamine's closed-lid support and display-specific controls are essential for developers using clamshell mode. Triggers can auto-activate when external displays connect.
3Presentations and screen sharing
Caffeine's simplicity shines here. No risk of complex settings interfering—just click and present. The duration timer can auto-disable after your meeting ends.
4Automated workflows and build processes
Use Amphetamine's triggers to keep Mac awake while specific apps (like build tools, renderers) are running. AppleScript support enables integration into automated pipelines.
Migration Guide
From_amphetamine → Caffeine
Uninstall Amphetamine from Applications folder. Download Caffeine from caffeine-app.net. No settings to migrate—Caffeine has no configuration. Click the coffee cup icon to begin using. Consider keeping Amphetamine installed if you occasionally need advanced triggers; both can coexist.
From_caffeine → Amphetamine
Download Amphetamine from Mac App Store. Caffeine settings don't directly transfer; manually recreate any duration preferences in Amphetamine's settings. Explore the Triggers section to replicate Caffeine's simplicity through automation—set up triggers for common scenarios so you rarely need to toggle manually. Keep Caffeine as a backup for quick toggles.
Final Verdict
tie
Winner
Runner-up
Amphetamine and Caffeine represent two perfect implementations of different philosophies. Amphetamine is the automation powerhouse—unmatched in features, triggers, and customization. Caffeine is the simplicity champion—unrivaled in ease-of-use and minimal resource footprint. Both are completely free and actively maintained in 2026.
Bottom Line: Choose Amphetamine if you need conditional automation, closed-lid support, or advanced triggers. Choose Caffeine if you want instant, zero-configuration sleep prevention. For most users, we recommend trying Caffeine first—its simplicity may be all you ever need. If you find yourself repeatedly toggling it on for specific scenarios, upgrade to Amphetamine and automate those conditions.
