Settle the compliance question first
Many advertising networks, marketplaces and social networks limit how many accounts one person or business may run, and using a tool to make separate accounts look unrelated can breach their terms even where it breaks no law. Agencies with written permission to manage client accounts and sellers running separate businesses are in a different position, but each platform's terms decide. Work out where you stand before you spend anything, because the risk of losing accounts and ad spend sits with you, not the vendor.
Price per profile is the number to compare
Every vendor here prices plans by how many browser profiles you can keep, so count every profile you'll keep, not just the ones open on a given day. At 50 profiles the spread is narrow: AdsPower charges $21 a month, GoLogin and Multilogin $29, Incogniton $29.99 and Dolphin Anty $40 for a single user. Team pricing changes the picture. AdsPower adds $5 a month for each extra member, Dolphin Anty's team plans start at $89 a month for 100 profiles, GoLogin charges nothing per member, and Multilogin's Business plan includes unlimited seats.
Budget for proxies alongside the browser
Each profile needs its own IP address to appear as a separate location. Some plans include proxy traffic: GoLogin adds 2 GB of residential proxy data from Professional 25, Multilogin's paid plans include 1 GB a month on Pro and 5 GB on Business, and Incogniton's paid plans come with free built-in proxies. Beyond those allowances, proxies come from a separate provider, so budget the two together. Check that the tool can assign proxies in bulk rather than one profile at a time; at 50 profiles, manual setup is slow work.
Team features matter more than fingerprint marketing
Fingerprint claims are hard for a buyer to check, while the operational side can be judged on a free plan or trial: sharing profiles between team members without exposing passwords, roles and permissions, activity logs, and whether a profile opened on one machine syncs to another. These differ by tool and plan. Dolphin Anty, Incogniton and Multilogin's Business plan have roles, AdsPower and Incogniton keep activity logs, GoLogin stores every profile in the cloud, and AdsPower keeps profile data on the device unless sync is turned on.
