Auto-login & Content Extraction from Captcha-Protected Websites Using Hidemium + n8n

Built with n8n

Hey n8n community! :wave:

I recently encountered a challenge: I needed to extract data daily from a web portal that blocks headless browsers and frequently throws CAPTCHA or fingerprint-based verification walls.

Headless scraping? Blocked. API? Doesn’t exist. Manual access? Time-consuming. So, I built a workaround using Hidemium and n8n.

:hammer_and_wrench: Here’s how it works:

  1. Hidemium creates a real browser environment with a clean fingerprint and a proxy — the website doesn’t flag it as a bot.
  2. Using Prompt Script AI inside Hidemium, I created a flow like:

“Go to login page, enter credentials, wait 5 seconds, solve CAPTCHA if present, navigate to dashboard, copy table data.”

  1. The result is posted to a local webhook in n8n as structured data or screenshot (depending on the case).
  2. n8n parses the incoming data → stores it in Google Sheets → sends notification if certain conditions are met.

:white_check_mark: Why Hidemium + n8n Works Well:

  • Most CAPTCHA pages don’t load unless fingerprinting looks legit — Hidemium takes care of that.
  • n8n handles all backend logic: retries, error catching, scheduling, and output.
  • Way more reliable than Puppeteer + stealth + captcha solver combo I used before.

If anyone’s working with difficult-to-automate websites that don’t expose data APIs or actively block automation tools — I highly recommend trying this browser-based + workflow-based combo.

Let me know if you’d like a sample script + JSON flow!

I’d love to see how you did this.

Hi, thank you for your solution.
I’m new and I was trying to do exactly that (login but blocking on captcha).
I’ll like to seen your sample script + JSON flow thanks

Perfect, I like this workflow

I can’t figure out the pricing.
What’s your experience?

I’ve actually tried a very similar setup with Hidemium + n8n, and it worked surprisingly well for a client dashboard that used aggressive fingerprint checks and reCAPTCHA.

The Prompt Script AI handled the login + navigation flow smoothly, and the browser environment passed all detection — way more stable than my old Puppeteer + proxy approach.

Once I had the data flowing into n8n, everything else (storage, alerting, retry logic) was just plug-and-play. Total game changer for scraping anything beyond static pages.

Thanks for sharing your setup — definitely second your recommendation!

This is exactly the issue I’ve been facing with a local B2B portal — headless gets blocked instantly and I’ve hit a wall with Puppeteer stealth.

Would love to try your Hidemium + n8n approach. Any chance you could share the Prompt Script and n8n flow template?

Hi, I was trying to do exactly the same thing but couldn’t figure out how to do it. Can you please share the flow template?
