Closing my MacBook used to kill whatever I had left running: a build, a download, sometimes an agent halfway through a task. I made Clamshell to fix that. The lid shuts, the screen goes dark, and the work carries on. No monitor, sudo, or admin setup.
Clamshell started with a very ordinary annoyance. I would close my MacBook, leave a build, download, or coding agent running, and come back later to find that the whole thing had stopped.
I tried the usual workarounds. Some only prevent idle sleep. Others change a system-wide setting that is easy to forget. I wanted one small switch I could turn on only when I needed it.
So I built Clamshell. Arm it, close the lid, and your Mac keeps working while the internal display goes dark. Open it again and normal lid behavior comes back. You can arm it from the menu bar, with a shortcut, or by holding Option while closing the lid.
It checks itself again when power changes. I also added a low-battery cutoff because keeping a Mac awake is not very useful if it runs the battery flat.
Setapp gave me a reality check before this launch: more than 500 people are already using Clamshell, and so far I have had one bug report. That bug is fixed.
If you prefer the direct version, the trial lasts seven days and does not ask for a card. After that, it is $9.99 once.
If you run long builds, downloads, local servers, or coding agents, I would genuinely love to hear how it works on your MacBook.

Hey Product Hunt,
Clamshell started with a very ordinary annoyance. I would close my MacBook, leave a build, download, or coding agent running, and come back later to find that the whole thing had stopped.
