The moment your MacBook lid closes, macOS clamshell sleep kills Claude Code, Codex and every local agent mid-task. RomeLid holds the lid one perfect centimeter open — so it never fires.
caffeinate can't blockYou kick off a 40-minute agent run. You close the lid to head out. You open it later — dead at 2%, progress gone.
It blocks idle sleep. Physically closing the lid triggers clamshell sleep — a different mechanism that fires instantly.
sudo pmset disablesleep 1 works — until you forget to undo it and cook your battery in a bag. Most devs won't touch it.
A fully open laptop can't go in a bag, invites spills and screen damage, and looks like an invitation to touch it.
Slide RomeLid onto the edge of your MacBook base. Soft pads grip without marks.
The lid rests on RomeLid ~1cm open. The lid sensor never reports "closed."
Pair with caffeinate -i and SSH/tmux and your agent runs until it's done — even from your bag pocket, vents clear.

Wide enough that the lid sensor never reports "closed." Narrow enough that the screen stays dark and the battery barely notices.
Every touch point is a soft pad. No adhesive, no residue, nothing rigid against aluminum or glass.
Lighter than your USB-C cable. Lives in the pouch until a long run needs to survive a commute.
RomeLid is newly launched — customer reviews will appear here as verified buyers leave them. We never publish fabricated testimonials.
Keep vents unobstructed and avoid sealed compartments during heavy compute. RomeLid keeps the lid ajar for airflow; for long heavy runs, bag-top or outer pocket placement is recommended. Monitor temps like you would any sustained workload.
No — every contact point is a soft-touch pad. No adhesive, no residue.
MacBook Air and MacBook Pro, 2016 and newer. Doesn't fit? Full refund.
caffeinate blocks idle sleep. Closing the lid triggers clamshell sleep — a separate hardware-sensor event. RomeLid stops the sensor from ever reporting "closed." Use both together for a bulletproof setup.
