SidePulse: Agent Status, at a Glance (LEDs in MacBook Pro SD Slot)

SidePulse, a new hardware accessory from Inteliwear, displays AI agent status through RGB LEDs that fit into a MacBook Pro's SD card slot or connect via USB-C, priced at $69 for the Pro model with 8 LEDs and $29 for the Dot with 2 LEDs. The device mounts as a filesystem, allowing users to control lights by writing to a file, and is designed for monitoring coding agents, builds, and background tasks, with initial support for Claude and Codex agents.

SidePulse Agent status, at a glance 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 . SidePulse Pro $69 8 RGB LEDs · MacBook Pro SD slot → SidePulse Dot $29 2 LEDs · USB-C · works everywhere → 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 on every 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 https://github.com/inteliwear/sidepulse/blob/main/LEDS FORMAT.md . 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.
