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.
| Testing job | Proxy type | Why | From |
|---|---|---|---|
| Release checks a few times a month | Eternal Residential | 80M+ IPs in 195 countries. The GB never expire, so quiet weeks cost nothing. | $0.75/GB |
| Mobile web and app behaviour | Mobile | Real 4G/5G carrier IPs show what people on phones are shown. | $4.40/GB |
| A fixed test IP your staging firewall can allow | Static Residential | A dedicated IP that stays yours, so it can go on an allowlist. | $1.49/IP |
| Continuous automated testing | Budget Residential | Our lowest per-GB rate for test suites that run all day. | $0.49/GB |
| CDN and cache checks at volume | Datacenter | The fastest route when a residential IP is not needed. | $0.84/GB |
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

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.
Is localization testing allowed on VantixProxy?
Checking your own sites, prices and checkout from other countries is a normal use of our proxies. Every customer agrees to our Acceptable Use Policy, so VantixProxy is not responsible for its users’ actions.
Testing apps and releases too
The QA and app testing guide covers regression runs by country, mobile networks and checkout flows.
