Semaphor: Uptime Widget

Semaphor answers simple question: Are my websites online and running? Stop finding out your site is down from a customer email.

PERFECT FOR
- Business owners wanting to know if their store is online
- Agencies and freelancers watching client websites
- Indie makers watching their own sites and landing pages
- Developers watching endpoints and APIs

FRESH WIDGETS
Semaphor has beautiful widgets so you can see your status anywhere on your screen.
Pick your refresh interval and turn on notifications so you never miss alert.

THE APP IS YOUR DASHBOARD
Add and organize your sites, see them all on one board, and tap any site for its response time, its recent checks and the latest HTTP result. Tap refresh to re-check every site at once.

TELLS YOU WHEN IT BREAKS
Turn on down alerts and Semaphor notifies you when a site goes red. Quiet hours hold alerts back overnight, and you can mute one site while you are busy fixing it.

SSL CERTIFICATES BEFORE THEY EXPIRE
See how many days are left on a site's SSL certificate and who issued it, and get a warning 14 days and 3 days before it expires.

UPTIME HISTORY
Uptime over 7 and 30 days, total downtime, the longest outage and the average response time, per site and across all of them.

PRIVATE BY DESIGN
No account, no sign-up. Semaphor contacts the websites you add and nothing else, and it stores your list and results on your device. No analytics, no tracking, no data collected about you. Ever.

UPGRADE IF YOU NEED MORE
Full version contains: Unlimited sites, down alerts, quiet hours, every check interval, website history, every widget size.
