What is net-merge?

net-merge combines your computer or phone internet connections to increase download and upload speeds. It works with Wi-Fi, Ethernet, and mobile data from a phone hotspot or USB tethering. The app runs locally without requiring an account, external server, or virtual private network.

The software routes each new network request to a single available connection. It automatically favors faster links and stops sending traffic to inactive ones. A menu bar or system tray interface shows individual connection speeds and allows you to pause or disable merging.

Speed increases only apply to applications that open multiple simultaneous connections. Single-threaded downloads do not benefit. The tool supports Windows, macOS, Linux, and Android, and is released under an MIT license.

net-merge FAQ

Is net-merge free?

Yes, the application is completely free to download and use. It is also open source under an MIT license.

Does net-merge work on Mac?

Yes, net-merge is available for Windows, macOS, and Linux. On Mac, it lives in the menu bar.

What is net-merge used for?

It combines multiple internet connections like Wi-Fi, Ethernet, and mobile hotspots to increase speeds for apps that open many simultaneous connections.

Can I combine Wi-Fi and mobile data on my computer?

Yes. You can connect your phone via USB and enable tethering, or join its hotspot. net-merge will use that alongside your existing Wi-Fi or Ethernet.

Does net-merge send my data to a server?

No. The app runs entirely on your device. Your traffic goes directly out through your own connections. It only contacts 1.1.1.1, 8.8.8.8, and GitHub to verify internet access and check for updates.

Will a single large file download get faster?

Only if the download client splits it into multiple connections. A single connection always uses one link, so net-merge cannot speed up single-threaded transfers.
