Best Free Alternative to Caffeinated for Mac
Caffeinated ($3.99 on the Mac App Store) is a polished anti-sleep utility developed by Yugen GmbH that keeps your Mac awake when you need it most—during video calls, presentations, file downloads, or media playback. It lives in your menu bar as a friendly coffee cup icon, offering one-click activation, an integrated timer, and optional notifications. For users who appreciate its minimalist design and reliable core functionality, Caffeinated delivers exactly what it promises without bloat. However, in 2026, many Mac users are questioning whether a $4 utility for preventing sleep is necessary when powerful free alternatives exist. The keep-awake utility market has matured significantly, with open-source and developer-built tools now offering substantially more features at zero cost. The primary free alternative, Amphetamine, not only matches Caffeinated's core functionality but dramatically exceeds it with advanced automation triggers, customizable hotkeys, AppleScript support, and a completely free price tag. Whether you're a casual user who occasionally needs to prevent screen dimming during a Zoom call, or a power user who wants sophisticated sleep management rules, you can achieve everything Caffeinated offers—and much more—without spending a dollar. This guide breaks down exactly how the free alternative compares and why switching makes financial sense.
Detailed Alternative Reviews
Amphetamine
The ultimate free keep-awake utility for Mac
brew install --cask amphetamineAmphetamine by William Gustafson is a powerhouse keep-awake utility that has remained completely free since its launch, with no advertisements, no in-app purchases, and no premium tier to unlock. It handles basic anti-sleep duties effortlessly—click the menu bar icon to prevent sleep indefinitely, for a set duration, or until a specific time. Where Amphetamine truly distinguishes itself is in its advanced automation capabilities. You can create triggers that automatically keep your Mac awake when specific conditions are met: while an external display is connected, when a particular app is running, during file downloads, while connected to specific Wi-Fi networks, when USB or Bluetooth devices are attached, or even based on CPU utilization thresholds. Amphetamine also uniquely offers the ability to keep your MacBook awake while the lid is closed, supports automated mouse cursor movement to prevent idle detection, and includes Drive Alive functionality to prevent external drives from spinning down. Despite its extensive feature set, the interface remains intuitive and the app is fully optimized for Apple Silicon Macs. For users migrating from Caffeinated, Amphetamine feels like an upgrade in every dimension while costing nothing.
Key Features:
- One-click activation with indefinite, timed, or scheduled keep-awake sessions
- Advanced triggers for automatic sleep prevention based on displays, apps, Wi-Fi, USB devices, battery status, and more
- Unique closed-display mode keeps MacBooks awake with the lid shut
- Drive Alive feature prevents external drives from sleeping
- Customizable menu bar icons, notification sounds, and hotkey shortcuts
- AppleScript support for automation and integration with other tools
- Optional session time remaining display in menu bar with 12/24 hour support
- 100% free with no ads, no tracking, no data harvesting, and no upsells
Limitations:
- • Vast feature set can feel overwhelming for users who only need basic sleep prevention
- • Interface prioritizes functionality over visual polish compared to Caffeinated's sleek design
- • Advanced trigger configuration requires some learning to set up effectively
Best for: Any Mac user who wants to prevent sleep, from casual users needing simple toggle functionality to power users requiring complex automation rules and closed-lid operation
Which Alternative is Right for You?
Preventing screen dimming during video calls and presentations
→ Both Caffeinated and Amphetamine handle this basic need perfectly. Click the menu bar icon before your Zoom meeting or Keynote presentation to keep your Mac awake. Amphetamine offers the same one-click simplicity with the added benefit of being free forever.
Keeping a MacBook awake while the lid is closed (clamshell mode)
→ Only Amphetamine supports closed-display mode, allowing you to keep your MacBook running while docked with external monitors even when the lid is shut. Caffeinated explicitly does not support this feature for safety reasons.
Automated sleep prevention when specific apps are running
→ Amphetamine's trigger system can automatically activate keep-awake when you launch specific applications like video editing software, development IDEs, or backup utilities. Caffeinated requires manual activation each time.
Downloading large files overnight without interruption
→ Both apps work for this use case, but Amphetamine offers more flexibility. You can set it to stay awake while a specific download manager is running, or use the timer to automatically allow sleep after a set duration once your download completes.
Preventing external hard drives from spinning down
→ Amphetamine's unique Drive Alive feature periodically accesses external drives to prevent them from sleeping, which is invaluable for backup workflows, media servers, or any setup requiring constant drive availability. Caffeinated does not offer this functionality.
Migration Tips
Switching from Caffeinated to Amphetamine
Migration is effortless since both apps live in the menu bar and use similar coffee-themed iconography. Simply install Amphetamine via the Mac App Store or Homebrew, grant it the necessary system permissions when prompted, and start using it immediately. You can run both apps side-by-side during your transition period to ensure Amphetamine meets your needs before uninstalling Caffeinated.
Setting up your first keep-awake session
After installing Amphetamine, click its menu bar icon to reveal session options. For Caffeinated users, the 'Indefinitely' option replicates the simple toggle you're used to. You can also explore timed sessions (1 hour, until 5 PM, etc.) and check the 'Prevent display sleep' checkbox if you want your screen to stay bright as well.
Exploring triggers for automation
Amphetamine's triggers are where it shines beyond Caffeinated. Open Preferences, navigate to Triggers, and create your first automation. A simple starting point is 'While App is Running'—select an app you always want your Mac awake for, like Final Cut Pro or Time Machine. Amphetamine will automatically activate when that app launches and deactivate when it quits.
Using hotkeys for keyboard warriors
If you prefer keyboard shortcuts over mouse clicks, Amphetamine supports customizable hotkeys. In Preferences > Hotkeys, assign shortcuts to start/end sessions, toggle display sleep prevention, or show the menu. This enables faster workflows than Caffeinated's menu-only approach.
