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.

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.
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.
To answer your forum question: lid cracked open like an animal, which is exactly the problem. What I'd want next is the reverse trigger -arm it until a given process exits, so the Mac finishes the build and then actually sleeps, instead of staying awake in my bag/bed/ table until the battery cutoff catches it. Is there anything like that on the roadmap?

That’s the main idea I’m exploring for 2.0: let a specific job finish, then return the Mac to normal sleep. The hard part is knowing it genuinely finished rather than guessing from a process disappearing. Which tool would you want this for first?
Clamshell
Fair. I built Clamshell around the part I kept forgetting: making the override temporary and getting normal lid sleep back cleanly when I returned. The safety and recovery around that were what I didn’t want to manage by hand.
