LANLink

LANLink is a free, open-source, Windows-first LAN file sharing and remote support application.

It enables computers on the same local network to discover each other automatically without requiring Windows SMB sharing configuration. Each computer runs its own LANLink service, discovers nearby devices using UDP broadcast, and exposes only folders explicitly selected by the local user.

LANLink is designed for offices, schools, businesses, and home networks where fast and secure local file sharing is required.

How It Works

Each computer runs the LANLink service.

LANLink automatically discovers nearby computers on the same LAN using UDP broadcast.

Only folders explicitly selected by the local user are shared.

No Windows network sharing configuration is required.

Installation

1. Open the GitHub Releases page.
2. Open the latest release.
3. Download the Windows package from the Assets section.
4. Extract the downloaded archive to a permanent location.
5. Run the installer included in the package.
6. Approve the Windows permission prompt if requested.
7. LANLink automatically starts after installation.
8. The dashboard opens at:

http://127.0.0.1:8764

No separate Python installation is required when using the packaged Windows release.

Startup

LANLink can automatically start when you sign in to Windows.

The installer configures startup automatically.

Dashboard

The local dashboard is available at:

http://127.0.0.1:8764

The dashboard allows users to:

• View discovered devices
• Manage shared folders
• Configure application settings
• Monitor transfer status
• Start remote support sessions

Shared Folders

LANLink never shares files automatically.

Users must explicitly choose which folders will be shared.

Folders can be added or removed at any time from the dashboard.

Security

LANLink is designed for trusted local-area networks.

The application:

• Shares only user-selected folders
• Does not upload files to cloud services
• Does not require SMB sharing
• Does not expose files to the public internet
• Does not collect analytics
• Does not display advertisements

Users should operate LANLink only on trusted private networks.

Privacy

LANLink operates primarily within the local network.

No online account is required.

No personal data is collected for analytics or advertising.
