Multi-window sync: do it once in one window, finish in all of them
The same reply, the same price edit, the same listing step, repeated by hand across dozens of accounts, is the most draining part of multi-account work — and the easiest place to skip a window without noticing. Tick the windows, pick a master, hit start, and every click, keystroke and scroll in the master is mirrored to the rest in real time.
Ticking and clicking only — not a single line of script.

Repeating one action dozens of times — what it really costs
Window sync is not about speed. It is about the fact that doing the same thing forty times by hand guarantees mistakes you will only discover days later.
The same action, forty times over
One price change, one identical message, one daily check-in becomes thirty repetitions across thirty accounts. It eats a morning, and even then you cannot be sure every account actually got it.
Window switching hides mistakes
With windows stacked on top of each other it is easy to skip an account or do the same one twice. You find out days later when the numbers do not match, and fixing it costs more than doing it right did.
Batch work means learning to script
Every "just automate it" answer starts with Selenium, XPath and selectors. By the time an operator has a working script, the platform has changed its markup and maintenance costs more than the manual work.
Outsourced control means handing over accounts
Giving accounts to a third-party control tool means giving away live sessions and passwords. If something goes wrong, nobody is accountable and the accounts may be used for something else entirely.
Why window sync matters
The old way
- The same action repeated by hand across dozens of windows
- Constant window switching, with mistakes easy to miss
- Batch work means learning to write scripts first
- Stacked windows leave you guessing which one is where
With NexBrowser
- Do it once in the master; every window finishes at the same moment
- All windows tiled on screen, so you can see progress at a glance
- Ticking and clicking only — no code required
- Toggle which actions sync and set the interval between them
What window sync gives you
What you see is what you get — usable from the first minute.
Real-time mirroring
Mouse clicks, keystrokes and page scrolling in the master window reach every child window in milliseconds.
Automatic arrangement
Built-in tile and cascade layouts line every window up in one click, across multiple monitors too.
No site or count limits
Sync works on any site and any account — as many windows as you select, adjustable at any time.
Configurable sync items
Toggle clicks, typing and scrolling independently, and set an interval between consecutive actions.
How master and child windows work: one action, dispatched in the same tick
The logic is simple. Among a set of open profiles you designate one as the master; the rest become child windows. From then on, the clicks, keystrokes and scrolling that happen in the master are captured and dispatched to every child window in the same tick. You are looking at one page, but dozens of accounts are performing the same action.
Worth stressing: sync copies actions, it does not merge identities. Each child window still runs inside its own profile, with its own fingerprint parameters, its own cookies and its own bound proxy, so finishing the work in one pass does not turn those accounts into one device on the platform side.
- Clicks, keystrokes and scrolling mirror to every child window in real time
- Each child window keeps its own fingerprint, cookies and exit IP — identities stay separate
- Pause at any time, and add or remove windows mid-session

Arrangement and sync options: keep dozens of windows visible and under control
The first problem with many windows is simply seeing them. Built-in arrangement offers tile and cascade layouts that spread the participating windows across the screen in one click, with split placement on multi-monitor setups. One glance tells you which window is stuck on a captcha and which one did not keep up.
The second problem is dispatching too fast. In sync options you can toggle clicks, keyboard input and scrolling independently, and set an interval between consecutive actions so pages have time to load and render. Any account that needs careful handling can be pulled out of the sync and driven on its own.
- Tile and cascade layouts, including split placement across monitors
- Clicks, typing and scrolling can each be switched on or off
- Set an interval between consecutive actions to control the pace

When to use window sync and when to use RPA
Window sync suits work where you are present and the actions vary: replies that are not identical, ad-hoc price edits, reviewing and picking things that need human judgement. Its advantage is zero configuration — you think of something and do it, with no flow to define in advance.
If the same steps repeat every day and you want them to run unattended, RPA is the better fit: chain open-page, wait-for-element, fill, click and extract into a flow, then schedule it or dispatch it to dozens of profiles at once. The two complement each other — many teams use sync for ad-hoc work and RPA for the daily routine.

The free plan gives you 1 member and 10 windows — enough to see sync in action.
Three steps to start syncing
From opening profiles to batch execution, everything happens in the UI — no config files, no scripts.
Open the profiles you want to sync from Window Management; each runs with its own fingerprint and proxy.
Open Multi-Window Sync, tick the windows taking part, and designate one of them as the master.
Hit start — from then on your actions in the master are mirrored to every child window, and you can pause any time.
Window sync FAQ
How many windows can I sync at once?
Sync itself sets no cap. How many you can run comes down to your machine (mainly RAM and CPU) and the window allowance on your plan. Most users sync anywhere from a dozen to several dozen windows on an ordinary work computer.
Does window sync make platforms link the accounts?
No. Sync copies your actions, not your session. Every child window keeps running inside its own profile with its own fingerprint parameters, cookies and bound proxy, so platforms still see independent devices.
Can I sync only some actions?
Yes. Under Sync Options you can toggle clicks, keyboard input and page scrolling independently, and set an interval between consecutive actions so they are not all dispatched at once.
Are windows arranged automatically?
Yes. Window Arrangement offers tile and cascade layouts that line the participating windows up across your screen in one click, including split placement on multi-monitor setups.
Can team members use window sync?
Yes. Window sync follows your team permission settings — members use it within the profiles they can access, and admins control by role who may start a sync and which profiles they can drive.
