Proxies for localization testing

Lowest rate for each. Every tier is on the pricing page.

Why localization testing needs proxies

Most of what changes by country is decided from the visitor’s IP address. You cannot test it from your desk.

Geo logic only fires on location

Redirects, language, currency, tax, consent banners and shipping options are chosen from the visitor’s IP. The only real test is a visit from that country.

A VPN is not what customers use

VPN and server ranges are often treated differently by CDNs, fraud checks and ad networks. A residential or mobile IP meets the same conditions a real visitor meets.

Every release needs the same checks

One script, run through a different country each time, turns a manual spot check into a repeatable test matrix for every release.

Which proxy for which testing job

Testing is light on bandwidth and uneven over time, so the never-expiring balance is usually the right start.

Run the same check from several countries

Put the country in the proxy password and rerun the same test. The example opens a page in a real browser through three countries, saves a screenshot of each and prints where the visitor was redirected. It uses the Eternal Residential format.

  • _country-DE Two-letter country code
  • _region- Region or state
  • _city- City
  • _session-qaDE Same ID, same IP for the whole test
  • _lifetime-10 Minutes to hold the IP, up to 60

Playwright (Python): screenshot the home page from three countries

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    for cc in ["US", "DE", "JP"]:
        browser = p.chromium.launch(proxy={
            "server": "http://et.vantixproxy.com:1000",
            "username": "USERNAME",
            "password": f"PASSWORD_country-{cc}_session-qa{cc}_lifetime-10",
        })
        page = browser.new_page()
        page.goto("https://example.com/")
        page.screenshot(path=f"home_{cc}.png", full_page=True)
        print(cc, page.url, page.title())
        browser.close()

curl: see the redirect a French visitor gets

curl -sI -x "http://USERNAME:[email protected]:1000" https://example.com/

Localization testing proxy questions

What is localization testing with proxies?

Visiting your own site or app through an IP in each target country to check what local visitors get: language, currency, prices, consent banners, redirects, payment and shipping options. To check how your ads appear abroad, see ad verification proxies.

Which proxy is best for localization testing?

Eternal Residential for most teams, because testing is occasional and the balance never expires. Add Mobile proxies for mobile behaviour and a Static Residential IP when a firewall has to allow you in.

Why not just use a VPN?

A VPN exits from server ranges that many sites and CDNs recognise, so what you see can differ from what a customer sees. It also gives you a handful of locations. Residential IPs cover country, region and city, and look like ordinary visitors.

Can my staging site allow only your IP?

Yes, with Static Residential. The IP is dedicated to you and does not change, so you can add it to an allowlist. Rotating IPs cannot be allowlisted because they change.

Can I test from a specific city?

Yes. The residential, datacenter and mobile products support country, region and city targeting.

Does it work with my test framework?

Yes. Every product speaks HTTP, and all but Eternal Residential Lite also speak SOCKS5. Playwright, Puppeteer and Selenium accept both. The setup guides have a working example for each.
