How to Sync Userscripts Across Multiple Devices

Userscript synchronization allows you to keep your custom browser scripts, automated tweaks, and UI enhancements consistent across all your computers and browsers. While standard browser sync features often leave third-party extensions untouched, popular userscript managers like Tampermonkey and Violentmonkey offer built-in cloud integrations to seamlessly mirror your script library. This guide explores the most effective methods to synchronize userscripts across multiple devices, comparing automated cloud backups, manual exports, and developer-oriented setups.

Automated Cloud Sync via Userscript Managers

The easiest way to keep your scripts updated across devices is by leveraging the built-in cloud storage options available in major userscript manager extensions.

1. Tampermonkey Cloud Sync

Tampermonkey supports native synchronization with several cloud providers, including Google Drive, Dropbox, OneDrive, and WebDAV.

• How to set it up:

1. Click the Tampermonkey icon in your browser and open the Dashboard.
2. Go to the Settings tab.
3. Scroll down to the Config Mode section and change it to Advanced.
4. Find the Sync section, choose your preferred cloud storage service, and toggle Enable.
5. Follow the authorization prompts to link your cloud account.
6. Repeat the process on your other devices using the same cloud account.

2. Violentmonkey Sync

Violentmonkey provides an equally streamlined, lightweight sync feature supporting Google Drive, Dropbox, OneDrive, and custom WebDAV servers.

• How to set it up:

1. Open the Violentmonkey Control Panel.
2. Click the Settings gear icon on the left menu.
3. Under the Sync section, select your desired cloud provider.
4. Authorize access and click Sync Now to push your current scripts to the cloud.

Alternative Synchronization Methods

If you prefer not to grant third-party extensions access to your cloud storage accounts, several alternative methods offer varying degrees of control.

Manual Export and Import

For a quick, one-time transfer without linking external accounts:

• Export your scripts as a single .zip or .json file directly from your userscript manager’s settings menu.
• Transfer the file to your target device via USB, email, or messaging apps, then use the Import feature in the destination browser.

Git-Based Sync (For Developers)

If you actively develop or heavily customize your scripts, hosting them in a private or public GitHub/GitLab repository provides version control alongside synchronization.

• Save your script .user.js files in a remote repository.
• In your browser’s userscript manager, add the script using its Raw URL from GitHub.
• Enable Auto-update in your manager settings. When you push changes to your Git repository, your devices will automatically fetch the updated script.
