Who Actually Uses Multi-Account Browsers? Adoption by Industry in 2026

Our read: e-commerce sellers are the biggest group of multi-account browser users, scraping engineers run the most profiles, and ad verification teams spend the most per seat. Three different questions. Three different winners. Almost every "who uses multi-account browsers" article answers only the first one and calls it a day.

Freelance job listings hint at why. Postings that ask for Playwright experience, proxy management and "browser profile management" are often filed under QA Testing or Data Entry, and they rarely say "multi-accounting." The category people associate with ad-account farms is increasingly used by data engineers, QA teams and agencies who describe the work in completely different words.

So the vocabulary has drifted, which means any survey that asks "do you use a multi-account browser for multi-accounting?" undercounts part of the market by construction.

This post is an industry breakdown: where the users are, how many profiles each vertical tends to run, and which segments are growing. There is no census behind it, and no published one exists, so the method comes first and the conclusions are stated as our reading, not as measured shares.

Method: What This Is Built From (And What It Isn't)

This is not a census. Nobody has one. Multi-account browser vendors don't publish breakdowns of their customers by industry, and the users least likely to answer a survey are the ones running the most profiles. What does exist is a handful of public signals, and this post reads them together:

1. Vendor use-case pages. Multilogin, GoLogin and AdsPower all publish "who this is for" pages. The ordering on those pages reflects where their sales attention goes, and a vertical that appears on all three is more mainstream than one that appears on only one.

2. Freelance marketplace listings. Job posts on Upwork and similar platforms that mention browser profiles, proxy management or automation. They are biased toward outsourced work, but they show the vocabulary drift described above, which surveys miss entirely.

3. Software review sites. Review platforms tag reviewers by company size and industry. The samples are small and skew toward buyers willing to write a public review, so treat them as directional.

4. Automated-traffic reports. Imperva's annual bad bot research and Cloudflare's published bot-traffic figures show how much of the web is automated. That gives context for the scraping segment, even though neither report measures multi-account browsers specifically.

5. The shape of each workload. A seller with three storefronts and a script that creates profiles for every crawl need very different numbers of them. Much of what follows reasons from what each job actually requires.

The honest caveat: none of these signals measures market share, so this post doesn't print percentages. A ranking you can check against your own experience is more useful than a decimal that looks authoritative and isn't. For the other side of the market, the companies protecting the sites people test and automate, see our anti-bot vendor market share post.

Multi-Account Browser Adoption by Industry: The 2026 Split

Look at columns two and three together. The gap between them is the whole story of this post.

E-commerce: Biggest Headcount, Smallest Profile Counts

The largest single group, and the least dramatic. A typical marketplace operator runs a handful of profiles: one per Amazon or eBay storefront they operate, one or two for supplier portals, maybe a separate one for a Shopify admin kept apart from the rest. Where a marketplace restricts sellers to one account, that rule applies however the browser is set up; a second account is only legitimate where the marketplace approves it.

That's it. No fleet. No API. They open the browser in the morning, click into a few profiles, and close it at night.

Which is why this segment is the biggest by headcount and nearly the smallest by profile count. It's also the segment where evaluation is easiest to get right: a two-storefront seller with a supplier login is a workload you can run end to end inside a seven-day trial, and there's no tier above you to graduate into afterwards. Plenty of people in this vertical will never run more than a handful of profiles, and pricing shouldn't assume they will.

If a store does run into an enforcement action, a browser is not the answer. Our suspension and appeal statistics post covers what happens next, including the official appeal routes.

Affiliate and Media Buying: Loudest, Not Largest

Second by headcount, and by a wide margin the loudest. This vertical produces most of the YouTube tutorials, most of the Telegram chatter, and most of the outrage when a vendor changes pricing.

Profile counts jump: dozens is normal, and the top end of this group, mostly agencies working across many client accounts, runs into the hundreds. Spend is price-sensitive in a way that surprises people who haven't sold to affiliates. These are operators tracking ROI daily, and the monthly tooling line item moves their decision more than any feature on the page does. The engine underneath matters far more than the price line, but price is what gets compared.

Here's the interesting part. Affiliate marketing no longer looks like the center of gravity. It hasn't shrunk; everything around it has grown. Yet most multi-account browser homepages still lead with ad-account imagery, as if this segment were the whole market.

Scraping and Data Engineering: The Lane Nobody Markets To

A mid-sized group by headcount that runs more profiles than anyone else. That asymmetry is the single biggest point in this post.

The reason is mechanical: a scraping team doesn't sit down and create profiles by hand. A script creates fifty, runs a crawl, retires forty of them, and creates sixty more tomorrow. Profile count stops being a headcount proxy and becomes a throughput number. Anyone pricing per profile is billing this customer for their concurrency, which is a strange thing to charge for.

We think this is the fastest-growing segment, and it's growing for a reason that has nothing to do with multi-accounting: automating your own workflows in a real browser has become more practical than maintaining a custom headless setup. Teams that used to hand-maintain cookies, storage and proxy settings around a bare Puppeteer install are moving to a real browser with an API in front of it, where each profile keeps that state for them. Where data collection is involved, it belongs within each site's terms, robots.txt and rate limits; our guide to collecting public data at scale covers that side.

What this segment actually needs: a REST API, CDP endpoints for Playwright / Puppeteer / Selenium, headless launch, and per-profile proxy routing that doesn't require a GUI. JustBrowser ships all of that in its one plan, through a local REST API. So do some competitors. But read three multi-account browser homepages and count how many mention Playwright above the fold.

QA, Ad Verification, and the Boring Money

Two small segments that behave nothing like the rest.

QA and cross-browser testing. They're testing signup funnels against fresh-user state, checking geo-gated pricing pages, and verifying multi-tenant SaaS isolation without polluting a shared staging account. Profile counts are modest and stable. These people file support tickets in complete sentences, with repro steps, and they don't churn over a price change. Our post on DNS leaks behind a proxy covers one setup detail that trips up cross-region tests.

Ad verification. Smaller still by headcount, and in our view the highest spend per seat in the market. Agencies and brands checking how creative renders across geos, devices and browsers need consistent, reproducible profiles plus enough coverage to sample dozens of markets. They budget per seat and per market, not per licence. The ad verification workflow post walks through what that job looks like day to day.

Both look to be growing faster than affiliate. Both are almost invisible in multi-account marketing. If you're wondering where the category's growth comes from in 2027, our bet is these two plus scraping, not the segment with the loudest Telegram group.

Our view: whichever vendor stops chasing affiliate volume and builds properly for QA and verification buyers takes the next three years of this category. Nobody has done it fully yet.

Worth flagging one adjacent point: ad verification teams and click-fraud detection teams are looking at the same traffic from opposite sides. ClickzProtect sits on the detection end, scoring traffic quality for operators buying paid clicks. Same signals, inverted job.

Three Rankings, Three Different Winners

Here is the read that is the reason this post exists.

Rank by users, and e-commerce wins comfortably. Rank by profiles under management, and scraping wins, far out of proportion to its headcount. Rank by spend per seat, and ad verification wins with QA second.

Almost nobody publishes the second and third rankings, so the category's self-image is stuck on the first, plus the affiliate segment, which is over-represented in every discussion because it's the one that talks publicly.

The practical consequence is pricing. If profile count and user count moved together, per-profile pricing would be a perfectly reasonable way to bill: you'd charge bigger customers more, which is the entire point of usage-based pricing. They don't move together. Not even loosely. So per-profile pricing works out to a random tax, and it lands hardest on the segment growing fastest. Flat pricing isn't generosity. It's just the model that matches the distribution.

For reference, JustBrowser's homepage carries a dated comparison with Multilogin, GoLogin and AdsPower, several of which price by profile tier or by seat. Their published prices change, so check each vendor's own pricing page before you budget against it. JustBrowser's side of that comparison is a single plan: $9.99/month for unlimited profiles, or $99.99/year, with team seats free and unlimited. The catch worth knowing on our side is that a free seat can only run profiles shared with it; anyone who needs to create their own subscribes.

What To Do With This

If you're an e-commerce seller, start on the trial. A week of full access covers more of this vertical's real workload than any feature matrix will tell you, and you'll know before the card is charged whether the tooling earns its $9.99.

If you're on a scraping or automation team, evaluate on the API before anything else. Every vendor talks up its engine; far fewer give you CDP endpoints and headless launch. Test whether you can create, run and destroy a profile without touching a GUI. If you can't, it won't hold up once your scheduler is driving it.

If you're running affiliate campaigns, check each platform's rules on multiple accounts first; a browser doesn't change what they allow. On the technical side, extension-based tools work in JavaScript. A native C++ engine sets identity parameters lower down — canvas, WebGL, audio, fonts — across 40+ parameters, so each profile stays internally consistent.

QA and ad verification folks: you're the customer this category isn't built for yet, which means you have more say than you think. Ask vendors for the workflow features and support commitments you need, and see who says yes.

One last note for anyone measuring their own traffic while running any of this: fingerprint-based analytics gets weird fast when your visitors are your own profiles. JustAnalytics takes the cookieless route, which sidesteps that particular headache. Both products are part of Velocity Digital Labs.

Frequently Asked Questions

Which industry uses multi-account browsers the most in 2026?

By headcount, our read is that e-commerce and marketplace sellers are the largest group, mostly Amazon, eBay, Etsy and Shopify operators running a handful of storefronts each, with affiliate marketing and media buying second. No census exists, so treat that as a ranking rather than a measured share. Headcount is also only one ranking: scraping and data engineering teams are a smaller group that runs far more profiles per account, and ad verification teams spend the most per seat.

Are developers and scraping teams really using multi-account browsers?

Yes, and we think it is the fastest-growing segment. Scraping and data engineering teams are a mid-sized group by headcount but run more profiles than anyone, because automated workloads create and retire profiles by script. Freelance job listings that ask for Playwright or Puppeteer experience alongside browser profile management point the same way. Vendors with a REST API and CDP support serve this lane; most multi-account marketing still ignores it.

Do QA and ad verification teams use multi-account browsers?

They do, and they are the quietest part of the market. QA and cross-browser testing teams run isolated profiles to test signup flows, geo-gated pricing and multi-tenant SaaS accounts. Ad verification is smaller by headcount but, in our view, spends more per seat than any other vertical, because agencies need consistent geo and device coverage plus support commitments. Both look to be growing faster than affiliate marketing.

How many browser profiles does a typical user run?

It varies enormously by vertical. An e-commerce seller typically runs a handful, one per storefront plus a couple of supplier accounts. Affiliate and agency teams commonly run dozens. Scraping teams can run hundreds or more, created and destroyed by script. That spread is why flat pricing matters: JustBrowser is $9.99/month for unlimited profiles, while several competitors price by profile count or seat, which penalizes exactly the automated workloads that are growing fastest.
