How do I get notified when a webpage changes?

You have a few good options, depending on how reliable and automatic you want it to be:

Simple options

• Browser extensions: Tools like Distill.io, Visualping, or Page Monitor can watch a page and notify you when it changes.
• Web services: These run checks for you and can send email, push, SMS, or webhook alerts.
• RSS feeds: If the site offers an RSS or Atom feed, that’s often the cleanest way to get update notifications.
• Manual diff tools: Good if you just want occasional checks, but not ideal for automatic alerts.

What to look for in a good monitor

• Can watch either the whole page or just a specific element
• Supports login-protected pages if needed
• Handles dynamic JavaScript content
• Lets you set check frequency
• Sends notifications via email, browser, mobile push, Slack, or webhook

If you want to build your own

A simple approach is:

1. Fetch the page HTML on a schedule
2. Extract the part you care about
3. Compare it to the previous version
4. Send an alert if it changed

Common ways to do this:

• Python: requests + BeautifulSoup + a scheduler like cron or APScheduler
• JavaScript/Node: axios or fetch + cheerio
• For dynamic pages: use Playwright or Selenium

Important caveats

• Some sites block automated requests or require CAPTCHAs.
• Pages with frequent ads, timestamps, or rotating content can trigger false alerts.
• Make sure monitoring the page complies with the site’s terms of service.

If you want, I can recommend:

1. a no-code tool,
2. a browser extension, or
3. a small script you can run yourself.
