Browser profiles for people who run many accounts

Every account gets its own browser.

Browz runs separate, saved browser profiles side by side on your computer. Each keeps its own sessions and storage, leaves through its own proxy with a matching timezone, and presents its own configuration.

crash, restart and recovery checks with sessions intact

Internal qualification, October 2026: Installed Chrome profiles on Apple Silicon, two full app restarts. These numbers describe browser configurations on one machine, not separate physical devices, and no tool can promise a website will never link two accounts.

Use cases

Made for people who run many accounts for a living.

Agencies, sellers, QA teams and researchers use separate profiles so one account’s history never leaks into another’s.

How it works

From a new profile to a saved session.

Create a profile, give it its own exit, sign in once, and come back to the same browser every time.

01 / 04

Create a profile for one account.

Name it, file it in a folder, and pick an engine: the Browz engine, with controls for each surface, or your installed Google Chrome with a lighter set of controls.

  • Nested folders, tags, notes and pins
  • Create one at a time or import a CSV
  • Lock a profile behind its own password
02 / 04

Give it its own exit.

Assign a proxy and Browz checks where it really exits. Timezone and WebRTC follow the measured exit, so the profile doesn't contradict its own address.

  • HTTP, HTTPS, SOCKS4 and SOCKS5, credentials sealed
  • Exit IP and location checked before use
  • Optional refusal to launch on a broken or moved exit
03 / 04

Sign in once. Come back to it.

Start the profile and sign in normally. Cookies, sessions and site storage stay with that profile when you stop it, and are there next time.

  • Storage isolated per profile
  • Survives app restarts and crashes
  • Paste cookies in to start a profile already signed in
04 / 04

Automate it, or hand it to an agent.

Every action in the app is on a local API. Start a profile and connect Playwright or Puppeteer, script it from the command line, or give an AI agent access through MCP.

  • Local API on your machine, token-protected
  • browz command-line tool
  • MCP server for AI agents

Why Browz

Everything you need to run accounts apart.

An operator’s console, not a toy: dense tables, bulk actions, and every state visible at a glance.

01

Separate, saved profiles

Each profile keeps its own cookies, storage, extensions and bookmarks, and returns exactly as you left it.

Learn more 02

A checked exit per profile

Assign a proxy, see where it really exits, and let timezone and WebRTC follow the measured exit.

Learn more 03

Two engines

The Browz engine gives every surface a control. Installed Chrome runs your own Google Chrome with lighter controls.

Learn more 04

Automation built in

A local API for everything the app does, a command-line tool, an MCP server and saved RPA flows.

Synchronizer

Tile running profiles on screen and send one navigation, click or typed text to all of them.

Teams

A workspace with roles, profiles shared at the access each person needs, one device at a time, and an activity log.

Privacy & control

Encrypted end to end. Yours.

Your profiles run on your computer, and what syncs through your account is encrypted on your device first: the server stores only ciphertext it cannot open. The app talks to its own engine over a loopback API that nothing else can use without a token.

Security & privacy
Server-blind syncProfiles and sessions sync end-to-end encrypted, with a key from your password
Sealed credentialsProxy passwords encrypted at rest, never shown again
Token-protected APILoopback only, with a rotating bearer token
Per-profile blocklistsRefuse chosen sites before any connection is made
Encrypted archivesExport a profile as a passphrase-protected .browzprofile file
Profile locksPut any profile behind its own password
No trackers hereThis site self-hosts its font and runs no analytics or ad scripts
Clear acceptable useBuilt for agencies, sellers and QA, not for fraud

The same plans. Half the price.

Free for 5 profiles. Pro from $4.99 a month, Business from $17.99 a month with unlimited members. Every plan about half the price of AdsPower, Multilogin and Dolphin Anty for the same number of profiles.

FAQ

Questions, answered.

What is Browz?

Browz is a desktop app for running many separate browser profiles side by side. Each profile has its own cookies, storage and saved sessions, its own proxy with a matching timezone, and its own browser configuration, so the accounts you keep in different profiles stay apart.

Is Browz an antidetect browser?

It is built for the same job: keeping accounts that should be separate from being tied together by shared storage, a shared IP or a contradictory configuration. We publish what we have measured and what we have not. No browser can promise that a website will never link two accounts, and we do not claim to.

Which proxies does Browz support?

HTTP, HTTPS, SOCKS4 and SOCKS5 proxies, with or without credentials. Browz checks each proxy's real exit address and location before you rely on it.

Is Browz free?

Nobody is charged during the private beta. There is a free plan with 5 profiles on your computer, without sync or team features, and paid plans from $4.99 a month: about half the price of AdsPower, Multilogin and Dolphin Anty for the same number of profiles. See pricing for details.

Which computers does it run on?

Mac and Windows. The Mac version (Apple Silicon, M1 or later) is in the private beta now, and the Windows version is joining the beta.

Can I bring my existing profiles?

You can import profiles from a CSV file today. Direct import from other multi-profile tools is in development and will be announced once it has been verified against each one.

Where is my data stored?

On your computer. Profiles and sessions stay on your machine, and proxy credentials are encrypted at rest and never shown again after you save them.

What is Browz not for?

Fraud, taking over accounts you do not own, bulk fake accounts on platforms that forbid them, or evading a ban imposed for abuse. Our acceptable use policy lists these and how we enforce them.
