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 icon

Amphetamine

Free keep-awake utility with more automation than Caffeinated

Mac App Store exclusive — Apple does not allow Homebrew distribution.

Download from the official site

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 icon

KeepingYouAwake

Open-source menu bar caffeine with Homebrew installs

brew install --cask keepingyouawake

KeepingYouAwake 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) icon

caffeinate (built-in)

Apple's free Terminal keep-awake command

brew install --cask caffeinate-cli

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/.

The verdict

Top pick

Amphetamine

Free App Store keep-awake with triggers, hotkeys, and closed-display mode that Caffeinated does not match at $3.99.

Runner-up

KeepingYouAwake

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.

Frequently Asked Questions

Is Amphetamine completely free or are there hidden costs?
Amphetamine is 100% free with no in-app purchases, subscriptions, ads, or tracking. Developer William Gustafson funds it via optional donations.
Can I install Amphetamine with Homebrew?
No. There is no Homebrew cask for Amphetamine. Install it from the Mac App Store, or use mas search Amphetamine / mas install with the Amphetamine app ID. Do not use brew install --cask amphetamine: that command fails.
What is KeepingYouAwake and is it still maintained?
KeepingYouAwake is a free open-source menu bar utility (Homebrew cask 1.6.8) that prevents sleep with one click. The project site is keepingyouawake.app and the GitHub repo newmarcel/KeepingYouAwake still saw activity into May 2026.
Does Amphetamine work on Apple Silicon Macs?
Yes. Amphetamine runs natively on Apple Silicon and is updated for current macOS releases. Caffeinated likewise supports Apple Silicon but requires macOS 15+ as of version 3.1.1.
Can Amphetamine truly replace everything Caffeinated does?
Yes, and more. One-click activation, timers, menu bar control, and notifications are covered. Amphetamine adds closed-display mode, triggers, hotkeys, AppleScript, and Drive Alive.
Is the built-in caffeinate command enough?
For many developer workflows, yes. caffeinate can keep the display or system awake and can wrap another process. If you want a persistent coffee-cup icon and clickable timers, use Amphetamine or KeepingYouAwake instead.
Why does Caffeinated cost money when free tools exist?
Caffeinated is a commercial Yugen GmbH product focused on polished design. Amphetamine and KeepingYouAwake are free community/indie tools. Pricing reflects business model, not a monopoly on the keep-awake idea.
Can I use Amphetamine on multiple Macs?
Yes. Because Amphetamine is free on the Mac App Store, install it on every Mac signed into your Apple ID. Caffeinated is $3.99 unless Family Sharing covers additional devices.
Does Amphetamine drain battery life?
The app itself is light. Preventing sleep uses more power because the Mac stays active. Amphetamine can keep the system awake while allowing display sleep, which helps overnight jobs.
Will Amphetamine keep my Mac awake when the lid is closed?
Yes, via closed-display mode. Caffeinated does not support lid-closed keep-awake. KeepingYouAwake and plain caffeinate are not substitutes for Amphetamine's clamshell workflow.
What is the best free alternative to Caffeinated?
Amphetamine for most people: free on the Mac App Store, more features than Caffeinated, including closed-display mode and triggers. KeepingYouAwake if you want a simple open-source brew install. caffeinate if Terminal is enough.
Amphetamine vs Caffeinated: which should I use?
Amphetamine unless you have a hard preference for Caffeinated's UI. Amphetamine is free and more capable. Caffeinated is $3.99 one-time, polished, and intentionally omits lid-closed keep-awake. Feature-for-feature, Amphetamine wins on price and automation.
Is KeepingYouAwake better than Caffeinated?
For a free simple toggle, yes. KeepingYouAwake 1.6.8 is free, open source, and installable with Homebrew. Caffeinated costs $3.99 and looks more designed. Neither matches Amphetamine's advanced triggers. Pick KeepingYouAwake when you want brew + simplicity.
Does Caffeinated work with the MacBook lid closed?
No. Caffeinated's App Store description states the anti-sleep feature does not work when you close the lid, for safety reasons. Use Amphetamine closed-display mode if you need clamshell keep-awake.
Caffeinated vs built-in caffeinate command: do I need an app?
Not always. If your need is "stay awake while this download or build runs," wrap the command with caffeinate. Buy or install a menu bar app only when you want persistent one-click control without opening Terminal.
Is Caffeinated worth $3.99 in 2026?
Usually no for features. Amphetamine is free and more capable. KeepingYouAwake is free for simple toggles. caffeinate is free in Terminal. Pay $3.99 only if you tried free tools and still prefer Caffeinated's interface enough to tip the developer.
Caffeine app Mac alternative free?
Yes. The classic Caffeine utility is long past its prime for modern macOS. Free replacements are Amphetamine (App Store), KeepingYouAwake (Homebrew/open source), and the built-in caffeinate command. Caffeinated is a paid spiritual successor, not the only option.
How do I keep my Mac awake during Zoom without buying an app?
Install free Amphetamine and start a session for the call length, use KeepingYouAwake's menu toggle, or run caffeinate -d in Terminal for the duration. Also check Zoom and macOS energy settings so the display is allowed to stay on while plugged in.
Why do free keep-awake apps need accessibility or helper permissions?
Preventing idle sleep uses system power assertions. Menu bar apps may request permissions so they can respond to triggers or control display sleep cleanly. Grant only what the app documents. caffeinate needs no App Store permissions because it is a system binary you invoke yourself.
