Many accounts, each on its own Run them all with confidence
- Separate, realistic fingerprints
- Cookies and cache kept apart
- A dedicated IP for every profile
Why do accounts keep getting linked?
The usual problems
- Switching accounts on one computer leaves identical device traits
- Several accounts sign up and log in from the same IP
- Platforms remember your browser fingerprint, even across accounts
- Shared accounts log in from constantly changing devices and places
With Killer Whale
- Every account gets its own device fingerprint
- Every profile uses its own exit IP
- Cookies, cache and local storage never mix
- Teams share profiles without handing over passwords
A separate browsing environment for every account
A fingerprint of its own
Browser type, resolution, fonts, language, time zone and more are set per profile, so each one looks like a different computer.
- Consistent parameters with no giveaways
- Generate one with a click if you prefer
Fully isolated data
Cookies, cache and local storage are stored per profile. One account's session never shows up in another profile.
- Sessions persist between launches
- Profiles can't see each other
Proxies by region
Bind a proxy from the right region to each profile. Time zone and language follow the IP, and the login location stays stable.
- HTTP, HTTPS and SOCKS5 supported
- One exit IP per profile
Teamwork without passwords
Share a profile and your teammate can use it right away. Passwords stay hidden, and every action is logged.
- Share by project
- Adjust permissions anytime
Built for this kind of work
Works on every platform you use
Optimized for cross-border commerce
Put each account in its own browser profile and bind a separate proxy IP to each one. Every account then has its own device fingerprint, login data and exit address, with nothing to link them.
Platforms use device traits, IP addresses, cookies and more to tell whether accounts belong to the same person. Anti-association keeps each account different on all of these, so they look like separate devices and networks.
Each profile has its own fingerprint and its own storage. Cookies, cache, local storage and extension data are never shared, and separate proxies keep the network apart too.
Window sync, a local API, bulk profile management, teamwork and the Killer Whale AI Agent take repetitive multi-account work off your hands.
The client runs on Windows, macOS and Linux. The download page recommends the right version for your computer.
