The problem
The hardest part of parallel work is remembering what’s waiting.
You start one task, jump to another, answer a message, then discover an agent has been waiting for approval for twenty minutes. Signal Lights keeps the state of your work visible, even when the windows aren’t.
Four states. Zero guesswork.
Glance once. Know what to do next.
02
Working
Your agent is moving. A warm pulse gives you confidence without demanding attention.
03
Finished, unread
The result is ready. Blue remains until you open the task, so completed work never disappears.
04
Finished and read
You’ve seen the result. The task settles into green and gets out of your way.

Questions, answered
Before you switch it on.
Does Signal Lights read my conversations?
No. It reads bounded local status metadata needed to determine whether a task is working, waiting, finished, or read. Conversation bodies are not copied or displayed.
Can I use only Codex or only Claude Code?
Yes. Onboarding connects the assistant you use. You can add the other integration later if your workflow changes.
Does it work with Claude Code in Terminal?
Yes. Official Claude Code hooks report local lifecycle events from terminal sessions. Some terminal-only sessions cannot deep-link back into Claude because Claude does not expose a link for every CLI session.
Can I use Signal Lights offline?
Yes. A successful subscription check keeps the app available offline for seven days. Signal Lights checks at most once a day and resumes automatically after you reconnect.
How do I cancel or change my plan?
Choose Manage Subscription in the Mac app to update your card, see invoices, cancel at the end of your billing period, or schedule a monthly or annual plan change for renewal.
What Mac do I need?
The current release supports Apple silicon and Intel Macs running macOS 13 or later.
