SidePulse
Your AI agents work while the lid is closed, while you're in another app, while you're across the room. SidePulse turns their status into light — a string of RGB LEDs that lives in a port you already have.
No driver. No app. The device mounts as a tiny filesystem, and you control the lights by writing a file: LEDS.LED.

Which one is for me?
- SidePulse Pro tucks into the SD card slot of a MacBook Pro — the slot that 99% of people never use. 8 RGB LEDs, inconspicuous when you want it, glowing when you need it.
- SidePulse Dot is a tiny USB-C dot with 2 LEDs. It works onevery Mac — Air, mini, iMac, Studio — and on iPhone, where the SidePulse app lets you drive it from the CLI or Shortcuts.
Both speak the same simple, CSS-inspired animation language. Learn it once, use it everywhere — the full syntax is in the LED format reference.
Don't want to learn it? Just ask your AI. Point your coding agent at the device and say "blink the lights green when the build passes" — it writes LEDS.LED for you.
Designed for the agent era
Coding agents, long builds, deploys, background jobs, downloads, reminders — anything that finishes when you're not looking. Give it a color.
First batch — built for enthusiasts. This is an early run for tinkerers and early adopters. The software is intentionally minimal right now, but it's fully hackable and agent-controllable — the device is just a file, so your own scripts and AI agents can drive the lights however you want.
Included from day one: agent monitoring (Claude & Codex), MacBook battery display, works with the lid closed, and lets your Mac sleep once your agents finish.
