A proxy changes one thing about a visit: the IP address. Everything else in the browser stays the same whichever IP you use, including cookies, saved logins, settings and the device details a site can read, such as screen size, fonts and graphics hardware. If an agency runs 50 legitimate client accounts behind 50 IPs but from one Chrome install, the platform sees one device with 50 addresses and may treat unrelated clients' accounts as linked.
Multi-account browsers, often sold as "antidetect" browsers, solve this by giving every account its own isolated, consistent profile with its own proxy. Client A's account never shares cookies, storage or settings with Client B's. The purpose is to stop legitimately separate accounts from being mistaken for one operator, always within each platform's terms. It is not a way to run accounts that a platform would not allow.
The main options for teams
The prices below are each vendor's published starting price when this guide was written. They change often, so confirm them on the vendor's site before you budget.
| Browser | Starting price | Where it fits |
|---|---|---|
| Multilogin | $99/mo+ | Larger agencies that want a broad feature set, cloud sync, team management and custom browser builds |
| Dolphin Anty | $89/mo+, free tier for 10 profiles | Affiliate and social media teams; lighter than Multilogin, with an easy interface |
| GoLogin | $24/mo+ | Cost-conscious teams that want most features in a cloud-based tool |
| Incogniton | Free / $29/mo | Small teams getting started, with a free tier of 10 profiles; fewer options as you grow |
| Kameleo | $59/mo+ | Teams whose work centres on mobile profiles |
| AdsPower | $5/mo+ team plans | E-commerce teams that want a low entry price and an API |
| Vision | Paid | Enterprise buyers that need custom integrations |
What to check before your team commits
- A proxy per profile, with HTTP, HTTPS and SOCKS5 support and DNS lookups sent through the proxy.
- WebRTC handling that reports the proxy's IP rather than your office's.
- Cookie and storage isolation, so profiles cannot read each other's data.
- Consistent profiles that keep the same settings from one session to the next.
- Team sharing with permissions, so staff open only the client profiles they manage.
- An API, if your team automates tasks with Puppeteer or Playwright.
Pairing profiles with our proxies
Each of our proxy types works with every browser listed above, over HTTP(S) or SOCKS5 with username and password sign-in. Here is a setup your team can repeat for every new client:
- Order one IP per client account: a sticky session, or a static IP from Residential Premium for accounts that stay signed in for long periods.
- Create one browser profile per account and name it after the client and the platform.
- Paste that account's proxy into the profile's proxy settings.
- Open My IP and the WebRTC leak test inside the profile to confirm the address.
- Share the profile only with the people who look after that client.
Mistakes that link accounts anyway
- One IP shared across several client profiles: it undoes the separation. One profile, one proxy.
- Cloning a profile to start a new account: cookies and settings come along with it, so create each profile fresh.
- Moving an account between proxy types or countries: keep each account on the same type and location so its sign-in history stays consistent.
