Hi everyone!
I recently built a hybrid automation stack to monitor visual changes on several web platforms that don’t play nicely with headless browsers or scraping tools. These are websites that detect Puppeteer, block API requests, or display content differently based on fingerprint or geolocation.
So here’s what I did using n8n and a stealth browser called Hidemium:
My Setup:
- Hidemium opens the real browser with a clean fingerprint and loads the target webpage
- A Prompt Script auto-navigates to the specific section (e.g., dashboard, promo page)
- Takes a screenshot of the rendered page
- Sends the image to an n8n webhook as base64
- n8n compares it with the previous version using an image diff tool or even AI to detect text differences
- If changes are found → sends alert via email, Discord, or Telegram
What This Workflow Solves:
- Detects UI changes that API/webhooks can’t track
- Works on highly dynamic websites (geo/content-sensitive)
- Doesn’t get blocked like traditional headless scrapers
- Keeps track of important updates visually over time
If anyone’s interested, I can share the n8n flow + sample Hidemium Prompt Script that makes this work.
Would love to hear if anyone else is using real browsers + n8n in a similar way!
