How to Use Proxies with undetected-chromedriver

Which proxy works best with undetected-chromedriver?

For most scraping, Residential Lite is the cheapest way to get home IP addresses in the right country. Use Residential when you need a particular state or city, and Unlimited Datacenter for targets in the United States that do not block data centre addresses.

Proxy settings for undetected-chromedriver: host, port and login

A BooProxies plan gives you four things: a host, a port, a username and a password. These are the values for Residential; the username and password are on your plan page.

Host	`resi.proxies.boo`
HTTP port	`8080`
SOCKS5 port	`1080`
Username	`USERNAME`
Password	from your plan page

The country and the session are chosen in the username, not in a separate setting. The generator on your plan page writes the username for you, and Targeting and sessions explains each part.

undetected-chromedriver proxy setup, step by step

Start a local forwarder that listens without a login and passes traffic on to the proxy with your login.
Point the browser at the forwarder with --proxy-server.

undetected-chromedriver proxy example

Start a forwarder (gost)

gost -L=:8899 -F=http://USERNAME:PASSWORD@resi.proxies.boo:8080

Python

import undetected_chromedriver as uc

options = uc.ChromeOptions()
options.add_argument("--proxy-server=http://127.0.0.1:8899")
driver = uc.Chrome(options=options)
driver.get("https://api.ipify.org")
print(driver.find_element("tag name", "body").text)
driver.quit()

Replace USERNAME and PASSWORD with the login from your plan page. The example asks an IP-check address, so the output is the address your request left from.

Rotating or sticky sessions for undetected-chromedriver?

For crawling many pages with undetected-chromedriver, leave the username without a session so every request leaves from a new IP address. For anything with steps that belong together, such as a login, a cart or a paginated search that sets cookies, add a session to the username so those requests share one address.

A sticky username looks like this:

USERNAME-country-us-time-600-session-a1b2c3d4

undetected-chromedriver proxy not working?

A small local forwarder solves this: it listens on your computer without a login and adds the username and password on the way out. See proxies with a login in tools that only take IP and port.
Run one forwarder per IP address you want. Each can carry a different session ID in its username.
A 407 error means the username or password was not accepted. Copy both again from your plan page, and check that nothing added a space or cut the username short.
If the IP address is in the wrong country, look at the username: the country code is part of it. More fixes.
