Puppeteer vs Selenium: Automation Framework Selection Guide

What's the difference between Puppeteer and Selenium anyway?

The old iron engaged in automation testing must have heard of these two tools, but many people can not distinguish their doorway. Simply put, Puppeteer is like a professional sniper, specializing in Chrome, while Selenium is more like a Swiss army knife, what browser can be tossed. For example, you want to batch collection of e-commerce prices, with Puppeteer faster; if you have to be compatible with different browsers to test, it is not Selenium.

How do proxy IPs play out in these two tools?

Do data collection is the biggest headache is IP blocked, this time you have to rely on the proxy IP to renew their lives. In Puppeteer to hang proxy, the code looks like a thief refreshing:

const puppeteer = require('puppeteer');
async function run() {
  const browser = await puppeteer.launch({
    args: ['--proxy-server=http://user:pass@ipipgo-proxy.com:8080']
  });
  // Normal operation afterward...
}

Selenium's proxy configuration is slightly more verbose and has to be handled with Options objects:

from selenium import webdriver
proxy = "ipipgo-proxy.com:8080"
options = webdriver.ChromeOptions()
options.add_argument(f'--proxy-server={proxy}')
driver = webdriver.Chrome(options=options)

Delineate the focus:No matter which framework you use, remember to choose a reliable agency service. Dynamic residential IPs like ipipgo's home, which comes with an automatic IP replacement function, can effectively avoid the anti-climbing mechanism.

What is the best way to choose between these two frames?

It's more visual to give the guys the whole comparison table:

If the project is in a hurry and you have to deal with complex web pages, close your eyes and choose Puppeteer. But if the father of the client wants to see the effect of Firefox, then we still have to use Selenium honestly.

Frequently Asked Questions QA

Q: Why is it still blocked even after hanging the proxy?
A: Mostly agent quality is not good, many free agents on the market are ten thousand people ride. Recommended to use ipipgo's exclusive IP pool, each session with a new IP, pro-measurement can carry a treasure anti-climbing.

Q: What if I need to operate multiple browsers at the same time?
A: You have to use a proxy IP pool at this point, assigning different IPs to each browser instance. ipipgo's API supports bulk IP acquisition, so you can just stuff it into a loop and use it:

ip_list = get_ipipgo_ips(count=5) take 5 fresh IPs at a time
for ip in ip_list:

Q: What should I do if I encounter a CAPTCHA?
A: A good agent can reduce the probability of triggering the CAPTCHA, but really encountered or have to pick up the coding platform. It is recommended to add a failure retry mechanism in the code, detecting the CAPTCHA will automatically change ipipgo's new IP to retry.

Say something from the heart.

The most fearful thing about automation is not code bugs, but being blackmailed by the target website. I've used seven or eight proxy services, and I've ended up using ipipgo for a long time just for the sake of stability. He has an "IP checkup" function is quite interesting, can automatically detect whether the proxy is exposed, which is particularly useful for brothers who need to run scripts for a long time.

Finally, I would like to remind newbies: Don't be lazy in proxy configuration! I've seen people because the proxy settings are not right, hard to Selenium into the "race of face ium", running half a day only to find that the IP did not take effect. It is recommended to set the proxy settings in thewhatismyip.comThese kinds of sites test the proxy to see if it works before you officially start messing around with it.
