"What's the best way to handle screen scraping without getting blocked?"
Yo, so I’ve been screen scraping for a while now, and man, getting blocked is the WORST. Anyone got tips to fly under the radar?
I’ve tried rotating proxies, slowing down requests, and even mimicking human clicks (lol). But some sites still sniff me out like a bloodhound.
Also, anyone use headless browsers? Do they help or just make it more obvious you’re screen scraping?
And yeah, I know some folks say "just use an API," but c’mon—half the time they’re either paywalled or don’t exist.
Spill your secrets, pls. 🙏

Dude, headless browsers can be a game-changer for screen scraping, but yeah, they can also make you stick out if you're not careful.
I’ve had luck with Puppeteer-extra and its stealth plugin—it masks a lot of the telltale signs that you're automating. Also, try randomizing mouse movements and scrolls.
Proxies are a must, but don’t just rotate them—use residential ones. Datacenter IPs are easy to spot. Check out Luminati or Smartproxy.
And for the love of god, don’t hammer the site. Random delays between 3-10 seconds help a ton.
If you're getting blocked while screen scraping, you might wanna check your headers. Some sites sniff out default User-Agents from tools like requests or selenium.
I use a list of legit User-Agents and rotate them. Also, spoofing referrers helps—make it look like you came from Google.
Oh, and Cloudflare is a nightmare. If you’re hitting a CF-protected site, you might need to use tools like undetected-chromedriver.
Honestly, the best way to avoid blocks while screen scraping is to not look like a bot. Sounds obvious, but most people skip the basics.
- Rotate IPs (residential proxies > datacenter)
- Mimic human behavior (random clicks, scrolls, delays)
- Avoid patterns—don’t scrape the same page at the same time every day
ScrapingBee’s API is a solid alternative if you’re tired of getting blocked. Worth the $$ if you’re doing this at scale.
Bro, I feel your pain. Sites are getting smarter at detecting screen scraping.
One trick that’s worked for me: throttle your requests based on the site’s traffic. If it’s a low-traffic site, go slow. High-traffic? You can be a bit more aggressive.
Also, check out Bright Data’s proxy manager—it handles rotation and geo-targeting automatically.
And yeah, headless browsers are great but only if you tweak ’em right. Default settings scream "bot."
If you’re screen scraping, you gotta think like a devops engineer.
Monitor your success rate. If it drops below 90%, something’s up.
Use a combo of:
- Rotating proxies
- Randomized delays
- Header spoofing
Tools like Scrapy + Scrapy-Rotating-Proxies can help automate this. Also, avoid JS-heavy sites unless you’re using a headless browser.
Wow, thanks for all the tips, y’all!
Definitely gonna try Puppeteer-extra and residential proxies. I’ve been using datacenter IPs like a noob, so that’s probably why I keep getting busted.
Quick question though—anyone know if using Tor for screen scraping is a good idea? Or is it too slow/unreliable?
Also, shoutout to the person who mentioned ScrapingBee. Gonna check that out too. Appreciate the help! 🙌
Lol, the eternal struggle of screen scraping.
Here’s what I do:
- Use Puppeteer with stealth mode
- Rotate IPs (residential, not datacenter)
- Randomize everything—timing, clicks, scrolls
Some sites just hate scrapers no matter what. For those, you might need to use a CAPTCHA solver (like 2Captcha), but that’s a last resort.
Yo, headless browsers are a double-edged sword. They’re powerful but can get you banned fast if you’re not careful.
Try this:
- Use Playwright instead of Selenium—it’s less detectable.
- Enable realistic human-like interactions (random pauses, mouse movements).
- Avoid headless mode if possible. Some sites detect it.
Also, check out Zyte (formerly Scrapinghub). They’ve got a smart proxy system for screen scraping.
Screen scraping is all about flying under the radar.
Here’s my go-to setup:
- Residential proxies (Oxylabs or Luminati)
- Randomized request intervals (2-15 secs)
- Full header rotation (User-Agent, Accept-Language, etc.)
If you’re still getting blocked, the site might be fingerprinting your browser. Try anti-detect browsers like Multilogin.
