Who Are the Best Proxy Providers? A Practical Shortlist of 5 Brands

What should an ad verification or automation team look for in a proxy provider? It's a fair question, because the usual comparisons focus on pool size and price per gigabyte, and neither tells you whether a provider can handle the way these teams actually work.

Ad verification means checking that ads appear correctly to real users in specific places. That requires IPs that look like local residents or mobile subscribers, often down to a city or a mobile carrier. Automation means running many browser profiles, scripts or bots at the same time, which requires enough simultaneous connections and reliable session control.

This shortlist explains both needs in plain terms, then compares five providers on how well they meet them. Each profile highlights what matters most and what to watch out for, and the FAQ at the end answers common beginner questions.

ProxyEmpire	Included at no charge	No cap, approved use cases	$3.50 a gigabyte	$1.97 for residential and mobile
Bright Data	Mentioned on its services page	Not stated	$4 a gigabyte with code	Card-free trial
Proxy-Seller	Yes, on per-proxy mobile	Unlimited	$1.45/GB volume	$3.50/GB test option
Webshare	No mobile product	Not stated	One gigabyte at $3.50	Ten free datacenter proxies
SOAX	ISP and ASN filters on mobile	Not stated	Set by country tier	Sandbox at no cost

How to Choose the Right Provider

Start with targeting. For ad verification, you need to appear in the exact place your audience is. Check whether a provider offers city and ZIP targeting on residential IPs and carrier targeting on mobile IPs, and whether those options cost extra.

Next, check concurrency. Concurrent sessions are the number of connections you can run at once. Automation teams running dozens of profiles need a high or unlimited limit, otherwise jobs queue up and slow down.

Then look at session control. A rotating session gives a new IP on every request, which suits quick checks. A sticky session keeps one IP for a while, which suits logging in or following an ad through to a landing page.

Finally, consider how you'll test. Since refund terms vary, a trial that covers the networks you'll use, especially mobile, saves you from buying the wrong plan.

It also helps to think about billing. Verification and automation work often follows client schedules, so traffic that rolls over or never expires keeps quiet months from wasting money. If several clients share one account, per-package spending limits make it easier to keep costs separate.

#1 ProxyEmpire

ProxyEmpire places no limit on concurrent sessions across its plans, a commitment its homepage qualifies with "for approved use cases." For automation teams, that means dozens of browser profiles or scripts can run side by side without hitting a connection cap. Each job can use its own session style: a fixed time, a full session or a new IP on every request.

For ad verification, its strength is precise targeting at no extra cost. Mobile IPs can be chosen by country, city and carrier, and residential IPs down to region, ZIP, ISP and ASN. Without a contract, a residential gigabyte is $3.50 and a mobile one is $4.50, unused GB roll over, and the company reports 4M+ mobile and 30M+ residential IPs. All sales are final, so the $1.97 trial covering both networks is the place to start.

Automation managers also get practical tooling: a public API that controls sessions, locations and settings, an endpoint generator, a free Chrome extension and an Android proxy manager. Integration guides cover antidetect browsers including Multilogin, GoLogin, Kameleo and Dolphin Anty, which many automation teams use to run separate profiles.

#2 Bright Data

Bright Data is built for large verification programs. Its residential network spans 400M+ monthly IPs in 195 countries, with free targeting by country, state, city, ZIP and ASN, and its proxy services page mentions carrier selection too. For global campaigns, that reach helps cover markets where smaller pools have few IPs.

Automation teams get a proxy management API, the company's own Proxy Manager tool and per-zone daily spending caps. A KYC check, which may include a video call, is required before residential or mobile use, and mobile proxies don't appear in its current pricing menus. Residential pay as you go costs $4 per GB with code RESIGB50, and certifications such as ISO 27001 and SOC 2 help with client audits.

#3 Proxy-Seller

Proxy-Seller offers carrier targeting on mobile proxies sold per proxy from $10, with rotation every 5 or 30 minutes or on demand. That suits verification teams that want a fixed set of mobile identities they can return to day after day, rather than a rotating pool.

Its residential plans include unlimited concurrent sessions and unlimited proxy lists, with volume pricing from $1.45 per GB. Residential traffic is valid for 30 days, and refunds must be requested within 24 hours. An API with SDKs in five languages helps automation teams order and manage proxies programmatically.

#4 Webshare

Webshare is a low-cost place to build and test automation. Ten datacenter proxies cost nothing and need no card, and its full API lets developers wire up scripts before scaling to paid plans. A single rotating endpoint moves through every IP an account holds, which keeps simple automation setups tidy.

Residential traffic starts at $3.50 for 1 GB, with ZIP and ASN targeting, and plans can be built around exact bandwidth and locations as a project grows. Because Webshare sells no mobile proxies, carrier checks require a second vendor alongside it.

#5 SOAX

SOAX fits agencies that check campaigns on behalf of many clients. Administrators can give every package separate ceilings on traffic, protocols and permitted domains, and mobile traffic can be filtered by region, city, ISP or ASN as well as country. Packages, sessions and reports are all reachable through its API, which helps agencies automate client setups.

Residential and mobile share one price by country tier, and rotation can trigger per request, by count, on a timer or on error. A free Sandbox account lets you explore before buying credits, and reports that split successful requests from blocked ones make client updates easier.

Frequently Asked Questions

What is ad verification?

Ad verification is the process of checking that online ads appear correctly, in the right places and to the right audiences. Proxies let verification teams see ads as users in specific cities or on specific mobile carriers would, which helps catch misplaced ads, wrong landing pages or campaigns that don't run where they should.

Why do automation teams need unlimited concurrent sessions?

Each browser profile, script or bot usually needs its own connection. If a provider limits concurrent sessions, large automation jobs have to wait in line. Among the providers here, ProxyEmpire and Proxy-Seller list unlimited concurrent sessions.

Is mobile traffic necessary for checking ads?

When the campaign runs on phones or inside apps, it is. Ads can differ by carrier, so checking from a residential connection may not show what mobile users see. Providers that sell mobile per GB make occasional checks affordable.

Can I test proxies before buying?

Yes. ProxyEmpire offers a $1.97 trial covering residential and mobile, Bright Data's trial is free and card-free, and Webshare offers free datacenter proxies. SOAX's free Sandbox account lets you explore its dashboard, and Proxy-Seller sells residential test traffic at $3.50 per GB.
