Software That Works With a Stateside Line, in the Order a Marketing Team Meets It
A Stateside Proxies line is three pieces of information, a host, a port and a login, printed on the line's card at base.statesideproxies.com, plus, on server-based lines, a VLESS link for anyone who wants a whole device in the United States. Any software that accepts a proxy accepts the line. This page lists the tools marketing, verification and QA teams actually use with it, in roughly the order a team meets them: a profile browser first, then the quick browser route, then phones, then the screenshot, QA and automation tools that turn checks into evidence. Each entry has the exact settings and one plain tip.
Undetectable.io
Profile browser, Windows and MacThe profile browser we point marketing teams to first. Every market gets its own browser window with its own clock, language, cookies and line, so screenshots from Chicago can never be confused with screenshots from Miami; the built-in test names the carrier and city before a page loads; a team can sync profiles.
- Add the line in the proxy manager as a SOCKS5 entry, filling in host, port and login from the card, and call the entry after its metro.
- Run the entry's test; it should report the United States, the carrier and a city in the metro's state.
- Make one profile for the market, pick a Windows or Android fingerprint, and point it at that entry.
- Leave clock and geolocation to follow the line; set the language to US English; start the profile.
- Visit an IP lookup page inside it, confirm carrier and state, and keep that screenshot at the top of the market's folder.
- A profile per market is the rule that keeps reports clean.
- When a line shifts metro, change the entry once; every profile on it follows.
GoLogin
Profile browser, Windows, Mac, Linux, AndroidThe second profile browser we recommend, and the one for teams spread across offices: a market's profile lives in GoLogin's cloud with its line attached and opens identically from any colleague's laptop or from the Android app.
- Make a profile named after the market and accept the fingerprint GoLogin proposes.
- Under Proxy choose SOCKS5 and drop in the host:port:username:password string copied from the line's card.
- Run Check proxy; it should show the US flag, the carrier and a city in the metro's state.
- Leave clock and geolocation on Based on IP, choose US English, save.
- Share the market's folder with whoever verifies that market.
- A folder per market, shared with its verifiers, is the entire filing system.
- The Android app opens the same profile on a phone for in-app placements.
FoxyProxy
Browser extension, Chrome and FirefoxThe quickest way to put an ordinary browser on the line for a single look at a page, without a profile tool. Add the line once and switch it on and off from the toolbar.
- Install FoxyProxy from the Chrome Web Store or Firefox Add-ons.
- Add a proxy: type SOCKS5, the line's host and SOCKS5 port, and the login.
- Switch the browser to use that proxy for all sites, or only for sites matching a pattern.
- Load an IP lookup page and confirm the carrier and the state.
- In Firefox, enable proxy DNS so name lookups also leave through the line.
- Your browser's own clock and language stay as they are; for a consistent US visitor use a profile browser instead.
Hiddify
VLESS app, Android, Windows, macOS, LinuxA free app with the plainest interface for putting an entire phone or laptop in the United States. Bring in a server-based line's VLESS link and every app on the device travels through the line.
- Take the VLESS link from the line's card.
- In Hiddify pick Add profile, drop in the link, then connect.
- Visit an IP lookup page in any browser on the device; it should show the carrier and the metro's state.
- On Android, switch on per-app routing so only the apps being tested travel through the line.
- This is how in-app placements and mobile app QA are done.
- Treat the link as a password; issue a new one from the dashboard if it may have got out.
Shadowrocket
VLESS app, iPhone and iPadThe usual iPhone and iPad app for the line's VLESS link. Bring in the link and the device, or the apps you choose, travel through the US carrier address.
- Take the VLESS link from the line's card.
- In Shadowrocket tap Add Server, drop in the link, then connect.
- Visit an IP lookup page in Safari; it should show the carrier and the metro's state.
- Use global routing for a whole-device check, or write rules so only the US apps travel through the line.
- News and social apps opened this way show their US feeds and in-feed placements.
- A rotation leaves the link unchanged; the app reconnects on its own.
Playwright
Browser automation for screenshotsFor teams that script their screenshots: Playwright drives Chromium, Firefox and WebKit with a proxy per browser context and a time zone and locale per context, which is exactly the consistent US visitor a report needs.
- Launch the browser with a proxy option of the form socks5://host:port and pass the login as proxy credentials.
- Create a context with timezoneId set to the metro's zone and locale set to en-US.
- Open an IP lookup page first and assert the carrier before taking any screenshot.
- Visit the pages under check and save full-page screenshots named with URL and local time.
- Keep the pace human: a page every few seconds, not a page a second.
- A headed browser records video placements more faithfully than a headless one.
Puppeteer
Browser automation, ChromePuppeteer drives Chrome from Node and takes a proxy at launch; a small script can emulate a US phone's time zone and screen and capture the same pages from each metro in turn.
- Launch Chrome with the proxy-server argument set to socks5://host:port and authenticate with the login on the page.
- Emulate a mobile device and set the time zone to the metro's zone with the page's emulation methods.
- Load an IP lookup page and check the carrier before proceeding.
- Capture the pages under check as full-page screenshots with URL and local time in the file name.
- Pace requests as a person would; verification is looking, not crawling.
- Rotate the line between runs with the rotation link if a fresh address is wanted.
Google Sheets
ReportingNot a proxy tool, but where every verification ends: a sheet with one row per placement, listing metro, carrier, publisher, time, creative and landing page, with the screenshot linked. Clients read the sheet; the screenshots are the evidence.
- Make one sheet per campaign with columns for metro, carrier, local time, URL, creative seen, landing page, and a link to the screenshot.
- Paste the IP lookup screenshot link in the first row of each metro's section as proof of where the browser was.
- Add a row per placement as you capture it, in the moment rather than afterwards.
- Share the sheet with the client alongside the screenshot folder.
- Name screenshots metro-date-time so the sheet and the folder sort the same way.
- A short findings column, present, wrong creative, broken landing page, turns the sheet into the report.
BrowserStack
Cloud browser and device testingCloud browsers and devices for cross-browser QA. Their machines sit in datacenters, so geo-dependent checks need the line: set it as the session's proxy and the cloud browser exits from the US carrier address.
- In the session or tunnel settings, set the proxy to the line's host, HTTP port and login.
- Set the browser's time zone and locale to the metro where the platform allows.
- Open an IP lookup page in the session and confirm carrier and state.
- Run the geo, consent, currency and availability checks and capture screenshots.
- Layout tests do not need the line; geo, consent, currency and ad checks do.
- Parallel sessions can share one line within its connection limit.
curl
Command line checkFor the one colleague who likes a terminal: a single command through the SOCKS5 port against an IP lookup endpoint prints the carrier, the type and the state, and proves the line is live.
- Call curl with -x socks5h://username:password@host:port against an IP lookup endpoint that answers in JSON.
- Read the organisation, connection type and region fields in the answer.
- Keep the output with a timestamp as text-form evidence beside the screenshots.
- The h in socks5h sends name lookups through the line as well.
- Call the rotation link with curl and run the check again to see a new address from the same metro.
Two things every tool needs from you
The line decides where your traffic comes from and nothing else. The clock and the language your browser reports are set in the tool or the device and should match the metro the line sits in: Eastern for New York, Boston, Miami and North Carolina, Central for Chicago and Houston, Mountain for Phoenix, Pacific for Los Angeles, with US English as the language. Where a tool offers SOCKS5, choose it over HTTP; it carries every kind of traffic and keeps name lookups inside the line. The same login works on both proxy ports.
Proxy details or the VLESS link
Browsers, profile tools, screenshot services and scripts take the proxy details. Phones, laptops that should be entirely in the US, and networks that block ordinary proxy connections take the VLESS link through a small free app. Both arrive at the same metro on the same carrier; the difference is whether one program or a whole device makes the trip.
Rotation and moves across tools
Changing the line's address from the dashboard, the rotation link, the API or a timer is invisible to every tool here; whatever connects next uses the new address, and VLESS apps reconnect by themselves. Rotate between checks, not during one. After a free move to another metro, update the saved proxy once if the host changed, and update the clock setting to the new metro at the same time.
Integration questions
Where should a marketing team start?
Undetectable.io for a profile per market, FoxyProxy for a quick single look, Hiddify or Shadowrocket to put a test phone on the line.
Do I need a developer to use the line?
No. A host, a port and a login go into a browser or a profile tool; the automation tools are for teams that already script their screenshots.
Can several tools use one line together?
Yes, up to the line's connection limit, all leaving from the same carrier address in the same metro.
Do the proxy ports and the VLESS link share a login?
The two proxy ports share one username and password; the VLESS link carries its own identity inside itself.
