Hey Product Hunt! 👋 I built Latch because I kept losing overnight Claude Code and Docker runs the moment I closed my MacBook's lid — clamshell sleep kills everything, and caffeinate can't hold through it. Latch keeps the Mac awake with the lid shut, but the part I'm proudest of is that it knows when to stop: it watches the actual process (CPU + disk, children included), rides through an AI agent's "thinking" gaps, and puts the Mac to sleep the moment work ends. No timers, no guessing. And because a Mac that can't sleep in a backpack is a hazard, every safety guardrail ships ON by default — battery threshold, thermal watch, session caps, and a self-healing watchdog. Each session ends with a receipt ("claude · 3h12' · battery −18% · peak 71°C"), pushed to Telegram if you're away. Free tier forever, no account. Pro (closed-lid mode) is a one-time $7.99. I'd love your feedback — especially from anyone running long AI jobs on Apple Silicon. AMA! ☕
