Pulseous by Adam Mackey

Pulseous is a status monitor for Claude. It lives in your browser's toolbar, and one glance tells you whether every Claude service is up.

• A green checkmark while every service is operational
• An X the moment any service is degraded, down, or in maintenance: amber, orange or red by severity, blue for maintenance
• A grey question mark if the status page itself can't be reached

Click the pulse for the detail: every Claude service with its current state — claude.ai, the Claude API, Claude Code, Claude Console, Claude Cowork and Claude for Government — plus any open incident with its latest update, and scheduled maintenance windows. Each incident links straight to its page on status.claude.com.

WHY PULSEOUS
• Know it's Claude and not you, without leaving the page you're on
• Visible from every tab: the badge is always there
• Checks every five minutes, and every time you open it
• Light and dark mode, keyboard and screen-reader accessible

PRIVATE BY DESIGN
Pulseous asks for access to no websites at all. It reads Claude's public status feed — the same one behind status.claude.com — and nothing else. No account, no sign-in, no servers, no analytics. Nothing leaves your computer.

FREE
Pulseous is free and made by one person, with nothing locked. If it helps you out, there's a "buy me a coffee" link in the popup.
