Best Free Alternative to Caffeinated for Mac
Looking for a free alternative to Caffeinated on Mac? Install Amphetamine from the Mac App Store. It is free, has no ads or in-app purchases, and does everything Caffeinated's $3.99 one-time purchase does, plus triggers, hotkeys, and closed-display mode. If you only want a simple coffee-cup toggle with a Homebrew install, use KeepingYouAwake 1.6.8 via brew install --cask keepingyouawake. If you live in Terminal, use Apple's built-in caffeinate and pay nothing. Caffeinated by Yugen GmbH remains $3.99 on the App Store (version 3.1.1 as of October 2025 notes, requires macOS 15+). Pay only if you specifically want that app's design and already refuse free tools.
Search variants that should land here include "caffeinated free alternative", "caffeine mac alternative", "amphetamine vs caffeinated", "keepingyouawake vs caffeinated", and "mac keep awake free". The answer pattern is stable in August 2026: free menu-bar apps already solved keep-awake. Caffeinated's App Store listing still states that lid-closed anti-sleep is intentionally unsupported for safety. Amphetamine is the free app that fills that gap. KeepingYouAwake stays the tidy open-source Caffeine spiritual successor. caffeinate remains the scriptable system tool.
This guide compares Amphetamine, KeepingYouAwake, and caffeinate against Caffeinated on price, install path, automation, clamshell mode, and when $3.99 is still rational (almost never for feature reasons; only for personal taste). Verified against the Mac App Store listings, KeepingYouAwake's site and Homebrew cask, and caffeinate documentation. Decision tree in plain language: need clamshell or app-based automation → Amphetamine; want brew and a minimal icon → KeepingYouAwake; wrapping one command → caffeinate; love Caffeinated's design after trying free tools → pay $3.99 once. There is no hidden subscription on Caffeinated today; the issue is opportunity cost, not a bait-and-switch fee. Free tools already cleared the bar.
Detailed Alternative Reviews
Amphetamine
Free keep-awake utility with more automation than Caffeinated
Mac App Store / mas search Amphetamine (no brew cask)Amphetamine by William Gustafson is the free App Store keep-awake utility people should try before paying for Caffeinated. Basic use mirrors Caffeinated: click the menu bar icon for indefinite, timed, or scheduled sessions. The gap opens on automation. Triggers can hold the Mac awake when a display is attached, when Final Cut or Xcode is running, when a download is active, on a chosen Wi-Fi network, when USB or Bluetooth devices appear, or when CPU crosses a threshold. Closed-display mode keeps MacBooks awake with the lid shut, which Caffeinated's listing explicitly does not support. Drive Alive helps external disks avoid spin-down. There is no Homebrew cask. Install from the Mac App Store or with mas search Amphetamine. Do not run brew install --cask amphetamine. The app is free with optional donations, no ads, and no premium upsell. If your query was "free alternative to caffeinated", this is the default answer for GUI users.
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:
- • No Homebrew cask: install via Mac App Store or mas, not brew install --cask amphetamine
- • 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 toggles to power users requiring automation and closed-lid operation
KeepingYouAwake
Open-source menu bar caffeine with Homebrew installs
brew install --cask keepingyouawakeKeepingYouAwake is the free open-source menu bar utility closest to classic Caffeine. Version 1.6.8 is what Homebrew currently ships (brew install --cask keepingyouawake), and keepingyouawake.app plus GitHub newmarcel/KeepingYouAwake are the upstream sources. Click the icon, pick a duration, optionally auto-disable on low battery. It does not try to match Amphetamine's trigger matrix or closed-display mode. That is the point. If Caffeinated's $3.99 feels like paying for a polished cup icon and Amphetamine feels oversized, KeepingYouAwake is the middle free path with a real brew install. Maintenance into 2026 is the signal you want before trusting a menu bar utility with power assertions.
Key Features:
- One-click prevent sleep from the menu bar
- Pre-defined activation durations
- Optional auto-disable on low battery
- Retina and Dark Mode support
- Homebrew cask 1.6.8: brew install --cask keepingyouawake
- Open source with active GitHub maintenance into 2026
Limitations:
- • Fewer automation triggers than Amphetamine
- • No closed-display / clamshell keep-awake mode
- • No Drive Alive external-disk feature
Best for: Users who want a free Caffeine-style toggle with a clean Homebrew install
caffeinate (built-in)
Apple's free Terminal keep-awake command
built-in: caffeinate -d # or caffeinate -i <command>macOS already includes caffeinate in /usr/bin. No App Store, no $3.99, no third-party trust decision. caffeinate -d asserts display wake; caffeinate -i prevents idle sleep; wrap a long job so the assertion dies with the process: caffeinate -i make release or caffeinate -i curl ... . For downloads, compiles, and CI-like local scripts this is often better than a permanent menu bar app. The downside is the missing coffee-cup UI and the risk of forgetting a background assertion. Pair with Amphetamine or KeepingYouAwake when you want a clickable timer; start with caffeinate when the need is one long command.
Key Features:
- Built into macOS, no download required
- Display, idle, and disk sleep assertions via flags
- Can wrap another process so keep-awake ends automatically
- Scriptable in shell, launchd, and CI jobs
- Zero cost and zero App Store dependency
Limitations:
- • No graphical menu bar interface
- • Easy to forget an assertion running in a background terminal
- • No App Store-style triggers or closed-display helpers
Best for: Developers and power users who already live in Terminal
Which Alternative is Right for You?
Preventing screen dimming during video calls and presentations
→ Amphetamine or KeepingYouAwake both handle one-click keep-awake. Amphetamine is free forever; KeepingYouAwake installs via Homebrew if you avoid the App Store.
Keeping a MacBook awake while the lid is closed (clamshell mode)
→ Only Amphetamine supports closed-display mode among these free options. Caffeinated explicitly does not support lid-closed keep-awake for safety reasons.
Automated sleep prevention when specific apps are running
→ Amphetamine's trigger system can activate when Final Cut, Xcode, or a download manager is running. KeepingYouAwake and caffeinate require manual or scripted control.
Downloading large files overnight without interruption
→ Use Amphetamine timed sessions, KeepingYouAwake for a simple overnight toggle, or caffeinate -i wrapped around the download command so sleep returns when the job finishes.
Preventing external hard drives from spinning down
→ Amphetamine's Drive Alive feature is the free answer. Caffeinated, KeepingYouAwake, and plain caffeinate do not match that workflow.
Scripting keep-awake inside a build or backup job
→ Use the built-in caffeinate CLI. It is free, requires no App Store app, and ends automatically when the wrapped process exits.
Someone who typed "caffeine mac alternative" after the old Caffeine app broke on a new macOS
→ Do not buy Caffeinated by default. Amphetamine is the maintained free App Store successor most people want. KeepingYouAwake is the open-source brew path. caffeinate is the no-install path. All three beat paying $3.99 for basic anti-sleep.
Amphetamine vs Caffeinated for closed-lid music production with an external display
→ Amphetamine. Caffeinated documents that lid-closed anti-sleep is unsupported. Amphetamine's closed-display mode is the free feature that matches this studio clamshell setup.
Family Sharing household comparing one $3.99 purchase vs free apps on every Mac
→ Amphetamine installs free on every Mac signed into the App Store account. KeepingYouAwake installs per machine via brew. Caffeinated is $3.99 and supports Family Sharing, but free tools still win unless the household insists on that exact app.
Migration Tips
Switching from Caffeinated to Amphetamine
Install Amphetamine from the Mac App Store (or mas search Amphetamine). There is no brew cask. Grant permissions when prompted. You can run both apps briefly before uninstalling Caffeinated.
Trying KeepingYouAwake via Homebrew
Run brew install --cask keepingyouawake to get version 1.6.8. Confirm releases on keepingyouawake.app or github.com/newmarcel/KeepingYouAwake if you want to verify maintenance before switching.
Setting up your first keep-awake session in Amphetamine
Click the menu bar icon and choose Indefinitely to mirror Caffeinated's simple toggle. Explore timed sessions and the Prevent display sleep checkbox when you need the screen bright too.
Exploring triggers for automation
In Amphetamine Preferences > Triggers, start with While App is Running for tools like Final Cut Pro or Time Machine. Amphetamine activates and deactivates automatically.
Using hotkeys for keyboard warriors
Amphetamine Preferences > Hotkeys lets you assign shortcuts for start/end sessions. Faster than Caffeinated's menu-only approach.
Reach for caffeinate before buying anything
In Terminal, try caffeinate -d during a call or caffeinate -i long-running-command. If that covers your use case, you do not need Caffeinated or even a menu bar app.
Uninstall Caffeinated cleanly after a week on Amphetamine
Run both for a few days if you need a confidence window. Confirm your usual call, download, and presentation flows. Then delete Caffeinated from Applications and remove it from Login Items if present. You cannot "transfer" settings; recreate any timer habits as Amphetamine sessions or triggers.
Map Caffeinated timers to Amphetamine sessions
If you used Caffeinated for 30-minute and 1-hour blocks during calls, recreate those as Amphetamine timed sessions. Pin a hotkey for your most common duration so you never open the menu during a share screen. Test once before a real client call.
Script caffeinate for overnight rsync or Time Machine prep
Prefer caffeinate -i around the exact command that must finish. That way sleep returns when the job exits instead of leaving a menu bar assertion on until morning. Example pattern: caffeinate -i rsync -aP ~/Projects /Volumes/Backup/.

Full reviewKeepingYouAwake
Best free Homebrew and open-source path when you want a simple caffeine-style toggle without Amphetamine's depth.
Bottom line
Skip the $3.99 Caffeinated purchase unless you only care about that specific UI after trying free options. Amphetamine replaces it for free with more automation, including closed-display mode that Caffeinated deliberately omits. KeepingYouAwake covers brew users who want open source simplicity. caffeinate covers Terminal and scripted jobs. If your search was "free alternative to caffeinated" or "caffeine mac alternative", start with Amphetamine today, keep caffeinate in your shell notes, and only revisit paid utilities for taste. Verified August 2026 against App Store pricing, Homebrew cask 1.6.8, and vendor docs.
