Best Proxies for Antidetect Browsers: Cost per Profile

Sort your profiles into three buckets and buy separately for each.

Profiles that hold a login you cannot afford to lose. Marketplace seller accounts, ad accounts, social accounts with history. These need a static address that does not change between sessions and does not resolve to a hosting ASN. That means a dedicated ISP proxy, also sold as a static residential proxy, one per profile.

Profiles that browse but never authenticate. Competitor catalogs, ad creative checks, SERP snapshots, pricing pages, supplier sites. These do not need a fixed identity at all. A rotating datacenter plan priced by concurrency carries them for a flat monthly fee, and the per-profile cost collapses because dozens of profiles share the same plan.

Profiles on a target that rejects everything but cellular. A short list, and shorter than vendors imply. Pay mobile rates only after you have watched a static ISP address get rejected on that specific target.

SparkProxy sells the middle bucket: rotating datacenter proxies with unlimited bandwidth, 1M+ IPs across 80+ countries, priced per concurrent thread from $75/mo. It does not sell residential, ISP or mobile plans, so for the first and third buckets the recommendation below points elsewhere, and says so plainly. If you are still deciding whether you need a proxy layer at all, our post on why antidetect browsers need proxies covers that argument; this one assumes you have made it and are now writing a cheque.

An antidetect browser's job is to make each profile look like a separate device. It randomises canvas, WebGL, audio, fonts, screen metrics and the user agent, and it keeps cookies and storage in separate containers. Every one of those signals is under the browser's control.

The exit IP is not. It comes from whatever proxy you attach to the profile, and it is the one identifier the browser vendor cannot fake for you. Two profiles sharing an IP are two profiles with a hard, server-side link between them, no matter how different their fingerprints look. Platforms that care about multi-accounting check exactly this, because it is cheap to check and expensive to fake.

That is why the unit of purchase is the profile, not the seat. Read the proxy bill as: how many of my profiles need an address nobody else is touching this month, and how many can share. The test is simple. If the profile logs into an account that would hurt to lose, it needs its own address. If it only reads public pages, it does not.

Four products get sold for this, and they differ on two axes that matter: whether the address stays yours, and what kind of network the address belongs to.

The axis people get wrong is the second one. A rotating datacenter proxy and a rotating residential proxy behave identically from the browser's point of view. They differ in what the target sees when it looks up the address owner. A hosting ASN is a one-bit signal that the connection is not a household, and on consumer platforms that bit is often enough on its own. Our breakdown of ISP proxies versus residential proxies goes deeper on where that line sits.

The axis people over-weight is the first one. Rotation is not a stealth feature. It is a throughput feature. It lets you spread requests so no single address trips a rate limit. Applied to a profile holding a login, it does the opposite of stealth: the account appears to hop cities between page loads, which is a far louder signal than a boring static address in one metro.

Why "residential" alone is not an answer

"Buy residential" is the default advice and it hides the decision that matters. Rotating residential and static residential are sold under the same word and behave nothing alike. Rotating residential is billed per gigabyte and hands you a new address constantly. Static residential is billed per address per month and hands you the same one every time. For a profile with a login, the second is right and the first is actively harmful. For a scraper, the reverse.

Here is what the vendors publish, read on 23 September 2026. Each figure is an entry rate from that vendor's own page, and each vendor's real price depends on volume, term and location.

Three things fall out of that table.

A dedicated static address for one profile is cheap in isolation. Between roughly $1.47 and $2.70 a month depending on vendor and term. The bill only hurts because you multiply it by profile count, and because "dedicated" is the word that triples the price against "shared".

Shared static addresses are a trap for account work. At $0.23 or $0.27 they look like the obvious buy. The problem is in the name. You do not know who else is on that address or what they did with it last week, and on a consumer platform the address's history is part of your profile's history. Shared static is fine for a research profile that never logs in. For an account you care about, the $1.47 to $2.70 tier is the product.

Per-GB billing behaves badly for account work. A profile doing genuinely human browsing, with images, video previews and infinite-scroll feeds, can move 2 to 5 GB in a month. At Webshare's published $1.40/GB entry rate that profile costs $2.80 to $7.00 a month in bandwidth alone, which is more than a dedicated static address that never meters you. Per-GB is the right model for a scraper that fetches small JSON payloads. It is the wrong model for a human-paced browser session, because browsers are bandwidth hogs and you are paying for every ad and font they pull.

The honest answer is target-dependent, and anyone quoting a universal number is guessing. But the decision has structure.

One profile per address, always, for: marketplace seller accounts, advertising accounts, payment-linked accounts, and any account where a suspension costs you real money or history you cannot rebuild.

Two to five profiles per address is usually survivable for: low-stakes accounts on platforms that tolerate households, where several people genuinely could share one home connection. A family shares one IP. Five accounts behind one residential address is not inherently anomalous. Fifty is.

Unlimited sharing is fine for: profiles that never authenticate. If the profile only reads public pages, the linkage risk it carries is zero, because there is nothing to link.

The failure mode to avoid is subtle. Teams buy one good static residential IP, attach it to their five most important profiles because it is the "clean" one, and concentrate every valuable account behind a single point of failure. Spreading five valuable profiles across five cheap addresses beats concentrating them behind one expensive address.

Whatever browser you run, the proxy has to satisfy the same short list. GoLogin, Dolphin Anty, AdsPower, Incogniton and Multilogin all take proxies the same way: a per-profile entry with host, port, username and password.

Per-profile assignment, not a system proxy. The proxy must be set inside the profile, so each profile routes independently. If you set it at the OS level you have one exit for every profile, which defeats the entire exercise.

HTTP and SOCKS5 both available. Some browsers handle SOCKS5 more cleanly for UDP-adjacent traffic and WebRTC handling. Having both ports on the same credentials saves you re-buying when you switch. SparkProxy's gateway exposes HTTP/HTTPS on port 11000, sticky sessions on 11002 and SOCKS5 on 13000, all on gateway.sparkproxy.io.

Sticky sessions if the plan rotates. A rotating plan that changes address mid-page will break form posts and multi-step flows. A sticky session port holds one exit for a defined window, which is what a browser needs even for research profiles. Our explainer on sticky session proxies covers how the window behaves.

Username and password auth, not IP whitelist only. Whitelisting works until your own connection changes address, which happens on home broadband, on mobile tethering, and every time you move a machine. Credentials travel with the profile. SparkProxy plans include whitelist slots as well, from 5 on Starter to 25 on Plus, but credentials are the right default for browser profiles.

A geolocation that matches what you told the browser. This one gets missed constantly. If the profile is set to America/Chicago and the exit IP geolocates to Frankfurt, you have created a mismatch that is easier to detect than a raw datacenter IP. Check it before the profile does anything meaningful:

curl -x http://USERNAME:PASSWORD@gateway.sparkproxy.io:11002 \
     -s https://ipinfo.io/json

Read the country, region and timezone fields back, then set the profile's timezone, locale and WebRTC policy to agree with them. Most antidetect browsers will do this automatically from the proxy, but only if you let them, and the automatic setting is worth verifying once per batch of new IPs rather than trusting blindly.

Datacenter proxies get dismissed for antidetect work, and for account profiles that dismissal is correct. For everything else in the same browser, it is not.

A large share of the profiles in a working antidetect setup never log into anything. They open competitor storefronts, check how an ad renders in another country, pull search results from a different metro, watch a supplier's catalog page for a stock change, or verify that a landing page redirects correctly for a given geo. None of that authenticates. None of it carries linkage risk. All of it benefits from being fast and unmetered.

That is where a per-thread datacenter plan wins, and wins by a wide margin on unit cost. One SparkProxy Starter plan at $75/mo gives 100 concurrent threads with unlimited bandwidth on a 30-day term. Spread across 30 research profiles, that is $2.50 per profile per month with no traffic meter running while a profile loads a video-heavy page. Spread across 60, it is $1.25. The plan ladder runs Starter $75 (100 threads), Core $140 (250), Boost $240 (500) and Plus $440 (1000 threads), all unlimited bandwidth.

The limit is honest and worth stating: these exits resolve to hosting ASNs. On a consumer platform's login flow, that is usually enough on its own to earn extra verification. Do not point account profiles at them. Our guide to bypassing IP fingerprinting on clean datacenter subnets covers what datacenter ranges can and cannot survive.

For research profiles that only need pages fetched rather than browsed, there is a cheaper path still: skip the browser profile entirely and call an API. SparkProxy's Scraping API renders the page server-side and charges 1 credit for a plain fetch, 5 for a JS render, with 1,000 free credits and no card to start.

import requests

r = requests.get(
    "https://scrape.sparkproxy.io/api/v1",
    headers={"X-API-Key": "YOUR_API_KEY"},
    params={
        "url": "https://example.com/catalog",
        "render_js": "true",
        "country_code": "DE",
        "premium_proxy": "true",
    },
)
print(r.status_code, r.headers.get("X-Credits-Used"))

A profile you do not have to open is a profile you do not have to pay a browser slot for.

Here is the arithmetic on a concrete, deliberately ordinary setup. These are assumptions chosen to be plausible, not measurements from a test we ran.

The setup. 40 profiles total. 25 of them hold logins worth protecting, so each gets its own dedicated static address. 15 are research profiles that never authenticate and share one rotating datacenter plan.

Static addresses, 25 of them:

Research profiles, 15 of them: one SparkProxy Starter plan, $75/mo, 100 threads, unlimited bandwidth. Fifteen browser profiles will not come close to saturating 100 threads, which means the same plan absorbs growth without a second invoice.

Totals:

• Low end: $36.75 + $75 = $111.75/mo, which is $2.79 per profile across all 40.
• Middle: $50.00 + $75 = $125.00/mo, or $3.13 per profile.
• High end: $67.50 + $75 = $142.50/mo, or $3.56 per profile.

Now compare that with the browser licence. A 40-profile operation fits inside GoLogin's Professional tier, which its pricing page listed at $29/mo for 50 profiles on monthly billing when read on 23 September 2026, or inside Incogniton's Entrepreneur plan at $29.99/mo for 50 profiles on monthly billing from its own pricing page the same day.

The proxy layer costs roughly four times the browser licence. That ratio is the number to carry into a budget conversation, and it is the opposite of how most teams plan. They agonise over a $10 difference between browser tiers and then attach whatever proxy is nearest. Our comparison of antidetect browser pricing per profile and per seat breaks down the licence side; the cheque you should be scrutinising is this one.

What moves the total most is the split, not the vendor. Move five profiles from the account bucket to the research bucket and you save between $7 and $14 a month with no change in vendor. Move five the other way and you pay it. Auditing which profiles genuinely need a dedicated address is worth more than negotiating a discount.

Ask these in a support chat before the card comes out. The answers take minutes to get and every one of them has burned somebody.

1. Is this address dedicated to me for the whole term, or shared? "Static" and "dedicated" are different claims. Get the one you are paying for in writing.
2. What happens when an address gets flagged on my target? Free replacement, paid replacement, or nothing. Replacement policy is the single biggest hidden cost in account work.
3. Can I pick the city, or only the country? Country-level targeting is standard. City-level matters when the account's history says it lives somewhere specific.
4. What ASN do these addresses belong to? Ask for an example address you can look up. A vendor selling "residential" out of a hosting range will dodge this question, and the dodge is your answer.
5. Is bandwidth metered, capped, or throttled past a line? All three exist and are described the same way in marketing. A throttle is survivable, a hard cap at 3am is not.
6. What is the refund or trial window, and does it apply to static IPs? Trials frequently exclude the static products, which are precisely the ones you need to test.

If a vendor will not answer four of those six, that is the test result. Our checklist on spotting a fake proxy provider before you buy covers the rest of the diligence.

Buying rotating residential for account profiles. It is the most common purchase in this space and it is the wrong product. Rotation means the account's IP changes constantly, which reads as travel, which reads as compromise.

Setting the proxy once and never checking it again. Addresses get reassigned. Terms lapse. A profile that silently falls back to your office IP is worse than a profile that fails to connect, because it fails quietly and takes your other accounts with it.

Matching the proxy country to the target instead of the account. The address should match where the account claims to be, not where the site is hosted. An account with three years of history in Manchester should not suddenly appear from Virginia because Virginia had the cheapest IPs.

Treating the browser's built-in free proxies as a proxy layer. Several antidetect browsers bundle free proxy access at the entry tier. It is a genuine convenience for trying the product, not an identity layer for accounts.

Buying mobile because a forum said so. Mobile proxies are expensive because carrier-grade NAT puts thousands of real subscribers behind each address, which is exactly why they pass. That property also means you have no control over who shares your address. Buy them when a specific target has demonstrably rejected a clean static ISP address, not preemptively. The trade-offs are laid out in our post on mobile or residential proxies for account work.
