Browser profile

A separate browser identity inside an antidetect browser, with its own cookies, storage, fingerprint and proxy. To sites, each profile looks like a different person on a different computer, so accounts in different profiles share no trace.

Also called: antidetect profile, browser session, multi-account profile.

Castle, describing how antidetect browsers work, puts it this way: "Each browser profile runs in a fully isolated environment, with separate configuration files, cookies, and local storage." Its settings usually cover the operating system, browser version, screen, hardware, time zone, language, WebRTC behavior and proxy.

Antidetects price by the number of profiles. In October 2026, 100 profiles cost from $36 a month at AdsPower to $89 at Dolphin{anty} on monthly billing. Some vendors use another word: Linken Sphere calls them sessions.

The working rule is 1 account, 1 profile, 1 proxy. Moving an account between profiles or sharing a proxy across them links exactly what the profiles were meant to keep apart.
