ScreenPing

Watch a screen region. Get a Telegram ping when it changes.

Perfect for ticket queues, deployment dashboards, or anything you don't want to stare at.

How it works

1. Select a screen region to watch
2. Monitor — the app takes periodic screenshots of that region
3. Compare — each screenshot is diffed against the previous one (pixel-level)
4. Alert — if the change exceeds your threshold, a screenshot is sent to Telegram

Quick start

npm install
npm start

Requires Node.js 18+

Telegram setup

1. Open @BotFather in Telegram and send /newbot
2. Copy the bot token
3. Send /start to your new bot (so it can message you)
4. Paste the token into ScreenPing and click Fetch Chat ID

That's it — you'll now receive screenshots in Telegram whenever the watched region changes.

Global hotkey

Works even when ScreenPing is in the background.

Building

Each platform must be built on that platform — Electron does not support cross-compilation.

Platform	Command	Output
Windows	npm run build	dist/ScreenPing 1.0.0.exe (portable)
macOS	npm run build:mac	dist/ScreenPing-1.0.0.dmg
Linux	npm run build:linux	dist/ScreenPing-1.0.0.AppImage
