Cross-Geo Testing with Residential IPs

Test your website worldwide. See exactly what real users see — no proxies, no emulation.

The Problem

Your website may look and behave differently for users in different countries. Geo-restricted content, localized pricing, CDN routing, and regional regulations all affect the user experience.

Traditional testing uses VPNs or datacenter proxies — but these are often detected and served different content than real users see.

You need to test with the same browser environment your actual users have: real residential IPs, local DNS resolution, and authentic browser fingerprints.

How Ceki Solves This

  • ✓ Real residential IPs worldwide — not proxies or VPNs
  • ✓ See exactly what a real user in that country sees
  • ✓ Take screenshots for visual comparison across geolocations
  • ✓ Automate cross-geo testing as part of your CI/CD pipeline

Quick Example

import asyncio, os
from ceki_browser import connect

async def main():
    client = await connect(os.environ["CEKI_API_KEY"])
    options = await client.search({"geo": "DE"})  # test from German IP
    browser = await client.rent(options[0].schedule_id)

    await browser.navigate("https://staging.example.com/login")
    await browser.click(300, 250)  # submit button
    snap = await browser.snapshot()
    print(snap.title)

    await browser.close()
    await client.close()

asyncio.run(main())

Cross-Country Website Testing Without VPN: Using Real Residential Browsers

Show Less

Your website looks different in different countries. Not just language and currency — content delivery networks serve different versions, ad networks show regional ads, payment gateways display local options, and search results vary by location. VPNs and datacenter proxies can't reliably reproduce what a real user sees.

The problem with VPN-based geo testing

VPNs connect you through servers in other countries, giving you a different IP address. But websites are getting better at detecting VPN traffic: VPN IP ranges are known and flagged, VPN connections have datacenter-like fingerprints, DNS leaks can reveal your real location, WebRTC leaks expose your actual IP, and time zone and language settings may not match the VPN location.

When you test through a VPN, you're not seeing what a real user sees. You're seeing what a VPN user sees — and those experiences can be very different.

Residential browser testing

Real browser sessions from hosts in specific countries give you the authentic experience: real residential IP from that country's ISP, authentic locale, timezone, and language settings, genuine screen resolution and device profile, no VPN detection flags, and the exact same CDN edge node that real users hit.

This is critical for localization testing (verify translations, currency formatting, date formats), CDN verification (confirm content from right edge nodes), payment flow testing (regional payment methods), ad verification (see actual ads in specific markets), compliance checking (GDPR/privacy banners in EU), and performance testing (real-world load times from specific regions).

Automating geo tests

With API access, you can automate geo-targeted tests: search for available browsers in each target country, rent sessions sequentially or in parallel, navigate to your URLs, take screenshots, measure load times, verify content, compare results across geos, and close all sessions. This can run as part of your CI/CD pipeline.

Available coverage

The marketplace currently has hosts in 50+ countries spanning North America, Europe, Asia-Pacific, Latin America, Middle East, and Africa. Availability varies by country and time of day — high-population countries (US, UK, Germany, Brazil, India) have near-constant availability.
