Uptime watch

Your sites checked every minute from your phone, and a push notification when one goes down and when it’s back.

Get it

$ dukoi init uptime-watch

It makes a uptime-watch folder and deploys it. On the phone instead: Try a template → Uptime watch → Deploy.

What you get

A page with the last 30 checks for each site. A site counts as down after two failed checks in a row, so one slow answer doesn’t wake you.

192.168.0.112:3006

Down 3 min

Alerts go through ntfy, a free push app for Android and iOS with no account. The page shows a topic; subscribe to it in the app. To pick your own topic:

$ dukoi env set NTFY_TOPIC=my-long-hard-to-guess-topic

Make it yours

Five files. You only need to touch one.

sites.js: The sites to watch. Edit this one.
server.js: Checks, alerts and the page
public/index.html: The status page
package.json: Its name and packages
README.md: How to run it, in five minutes

Put your own sites in sites.js. Addresses on your Wi-Fi work too, which a server in the cloud can’t check:

export const sites = [
  { name: 'Shop', url: 'https://shop.example.com' },
  { name: 'Home router', url: 'http://192.168.1.1' },
]

$ dukoi deploy
