# Synchronize profiles

{% embed url="<https://www.youtube.com/watch?v=jTz7OIcn8lI>" %}

The synchronizer lets you run multiple browser profiles at the same time, mirroring every action from the main profile window to all child profiles in real time. Clicks, keystrokes, and page navigation in the main window are replicated instantly across every child profile.

{% hint style="warning" %}
The synchronizer is currently supported on Windows only. Support for macOS is not yet available.
{% endhint %}

Syncing multiple profiles is particularly useful for repetitive account tasks where you want multiple profiles to follow the same actions, such as:

* Opening and navigating through the same set of websites across multiple profiles
* Logging into multiple accounts and completing basic setup steps like language other preferences
* Running initial browsing sessions to build activity history and warm up each profile (account warmup)
* Verifying fingerprint and browser configuration across multiple profiles simultaneously
* Installing extensions or configuring browser-level settings consistently across profiles

### Start a synchronizer session

To start a synchronizer session, choose one profile as the main profile and one or more child profiles to mirror its actions.

> A synchronizer session requires at least 2 profiles and a maximum of 5. One main profile and up to 4 child profiles. Also, only one session can run at a time, therefore, starting a new session automatically stops the current one.

{% stepper %}
{% step %}

#### Set the main profile

In the profile list, click the three-dot menu on the profile you want to use as the main and select **Start Synchronizer (As Main)**.

<div data-with-frame="true"><figure><img src="/files/aD89u1o03yabugQHPysl" alt=""><figcaption></figcaption></figure></div>

The **Start Synchronizer** dialog opens with that profile set as the main.
{% endstep %}

{% step %}

#### Select child profiles

Select the profiles you want to receive mirrored actions. You can search by name or group. Every action performed in the main profile window will be replicated to each profile you select.

<div data-with-frame="true"><figure><img src="/files/VJXTN7khHBRdFYD6CzFp" alt=""><figcaption></figcaption></figure></div>
{% endstep %}

{% step %}

#### Start the session

Click **Start Sync**. All selected profiles open in separate browser windows. A management panel appears in the profile list confirming the session is active.
{% endstep %}
{% endstepper %}

### Manage a running session

While the session is active, the management panel remains visible on the profiles screen. The panel has three control groups.

These controls help you manage window layout, tabs, and text input without interrupting the session. Unless stated otherwise, each action applies across all connected profiles.

#### Windows

Use these controls to arrange browser windows across all profiles.

| Control            | What it does                                                      |
| ------------------ | ----------------------------------------------------------------- |
| **Tile**           | Arranges all open windows in a grid                               |
| **Overlap**        | Stacks all windows in the same position                           |
| **Resize to main** | Resizes all child windows to match the main profile's window size |
| **Bring to front** | Brings all browser windows to the foreground                      |

{% hint style="info" %}
We recommend using **Resize to main** to keep all browser windows the same size. Consistent window sizes help reduce fingerprint inconsistencies across profiles.
{% endhint %}

#### Tabs

Use these controls to manage tabs across all profiles.

| Control               | What it does                                                  |
| --------------------- | ------------------------------------------------------------- |
| **Close blanks**      | Closes all empty tabs across all profiles                     |
| **Close non-current** | Closes all tabs except the active one across all profiles     |
| **Clone main's tabs** | Adds the main profile's open tabs to all child profiles       |
| **Navigate to URL**   | Navigates the active tab of all profiles to a URL you specify |

#### Text

These controls send text input to all profiles directly from the management panel, without requiring you to type in the main browser window.

<table><thead><tr><th width="119.94921875">Control</th><th>What it does</th></tr></thead><tbody><tr><td><strong>Send text</strong></td><td>Types text into the focused field of every profile window. You can configure the keystroke delay between a min and max (default 20–80ms)</td></tr><tr><td><strong>Paste</strong></td><td>Pastes clipboard content into the focused field across all profiles</td></tr><tr><td><strong>Clear field</strong></td><td>Clears the focused input field across all profiles</td></tr></tbody></table>

### Stop the synchronizer

Click **Stop synchronizer** in the management panel to end the session, after which all profiles remain open but stop mirroring actions from the main profile.

<div data-with-frame="true"><figure><img src="/files/LhB9YvZhVr6x9Jd4xhas" alt=""><figcaption></figcaption></figure></div>

You can close individual child profile windows during a session without ending it, and the main profile along with any remaining child profiles will continue syncing, but closing the main profile window ends the entire session.
