Web Crawler Review: Scrapy vs Puppeteer Performance Comparison

Hands-on tool selection: real-life experience of a reptile veteran

Brothers engaged in data collection understand that the wrong tool can make you three days and three nights of work for nothing. Recently, people always ask me Scrapy and Puppeteer in the end which one is good to use, these two goods are like frying vegetables and non-stick iron pan -Use it for the right occasion to get resultsI'm not sure if you're a good person, but I'm not a good person. To cite a chestnut, last week I helped customers catch the price of an e-commerce platform, with Puppeteer to open 10 windows on the trigger anti-climbing, change Scrapy with ipipgo's agent pool, froze and ran smoothly for 8 hours without turning over.

Practical guide to avoiding the pit: proxy configuration to play this way

Add proxies to Scrapy's middlewares, remembering thisgolden combination::
1. Set up the ipipgo API interface in settings.py
2. Download middleware randomly switches request headers
3. Set random intervals of 0.5-3 seconds between each request (don't use fixed delays!)
Once I got lazy and didn't do random delays, and I ended up getting recognized in half an hour, and it took a change of ipipgo's premium IP to save the day.

Puppeteer is more about browser fingerprinting camouflage, remember to add it in the launch parameter:
-proxy-server=dynamic residential proxy address for ipipgo
-disable-blink-features=AutomationControlled
The actual test with this method, a travel site continuous collection of 30,000 pieces of data was not blocked.

Seven Questions You're Sure to Ask

Q: Why am I still recognized after changing my IP?
A: Ninety percent of the IP quality is not good, free proxy basically with black history. It is recommended to use ipipgo's exclusive high-storage IP, and remember to clear the cookies for each request.

Q: Do I have to use Puppeteer to capture dynamically loaded content?
A: Not necessarily! Scrapy with splash can also render JS, but want to perfectly simulate manual operation, or Puppeteer + ipipgo dynamic IP is more stable!

Q: What should I do if my proxy IP is too slow?
A: Try ipipgo's BGP hybrid line, the measured download speed is 3 times faster than ordinary agents, especially suitable for the need for a large number of picture collection scenarios!

Ultimate Choice Recommendations

If you ask me.Scrapy + ipipgo static proxy for large data volumes, like doing long-term tasks like price monitoring. If you need to use Puppeteer + ipipgo dynamic residential IP, such as collecting social media data. Recently found a tart operation: with Scrapy scheduling Puppeteer instances, with ipipgo double authentication proxy, perfect solution to the problem of CAPTCHA.

A final reminder to novice brothers:Never save money on an agent.The last time I used an inferior agent, the data collected was misplaced! The last time with poor quality agent led to the collection of data misplaced, the customer almost did not give the settlement. Now fixed with ipipgo package, with automatic replacement of invalid IP function, the degree of peace of mind directly pull full.
