the door.
Lock your screen. Walk away. Holdor prevents macOS from sleeping while your AI agents are running. Claude, Cursor, Windsurf, VS Code, terminals — all protected.
The Problem #
macOS Sleeps
Lock triggers idle sleep. Your long-running AI agents get killed mid-task.
The Workaround
Carry your laptop everywhere? That's not a solution. That's a problem.

What Holdor Protects Against #
Regular Mode
Default. Prevents idle sleep so your Mac stays awake when you walk away.
- Screen lock
- Display sleep
- Idle sleep prevention
- System sleep (lid close)
- Manual sleep (Apple menu)
Extended Mode
Also prevents system sleep on lid close. Great for plugged-in setups.
- Screen lock
- Display sleep
- Idle sleep prevention
- System sleep (lid close)
- Manual sleep (Apple menu)
Manual sleep (Apple menu > Sleep) cannot be overridden by any app. This is a macOS security boundary.
Features #

FAQ #
- How does Holdor prevent macOS from sleeping?
- Holdor uses macOS's built-in
caffeinatecommand, tied to each app's process ID. In Regular mode it usescaffeinate -i -w PIDto prevent idle sleep. In Extended mode it adds the-sflag to also prevent system sleep (e.g. lid close). When the watched app quits, the assertion is automatically released. - What's the difference between Regular and Extended mode?
- Regular mode prevents idle sleep — your Mac won't go to sleep from inactivity. Extended mode additionally prevents system sleep triggered by closing the lid. Extended mode is ideal for plugged-in desktop setups. Both modes allow the display to turn off and the screen to lock normally.
- Does Holdor drain my battery?
- Holdor itself uses negligible resources — it's a native Swift app with no Electron runtime. In Regular mode, it only prevents idle sleep while watched apps are running. In Extended mode, your Mac stays awake even with the lid closed, which will use more battery if unplugged.
- Which AI coding tools does Holdor support?
- Holdor has built-in support for Claude Desktop, Cursor, Windsurf, VS Code, Zed, ChatGPT, Warp, Terminal, iTerm, and Ghostty. You can also add any macOS app via the native Finder file picker. Terminal apps cover CLI tools like Claude Code and OpenCode.
- Can I lock my screen while Holdor is active?
- Yes — that's exactly the point. Holdor prevents sleep but allows the display to sleep and the screen to lock. Your security policy is satisfied while your AI agents keep running in the background.
- Is Holdor free?
- Yes — Holdor is completely free and open source under the MIT license. The source code is available on GitHub. If it saves you from carrying your laptop around, you can optionally buy the developer a pasta.
