net-merge is a free, open-source networking utility that distributes internet traffic across multiple available connections. It combines Wi-Fi, Ethernet, and mobile tethering links to improve aggregate bandwidth utilization. The software assigns new network connections to available adapters based on their relative performance. Applications using multiple simultaneous connections can benefit from the combined capacity of different networks. It supports TCP and UDP traffic over IPv4 and IPv6 without requiring a proxy, VPN, or external server. Unavailable connections are automatically excluded until connectivity returns. A system tray interface displays network activity and connection statistics. Available for Windows, macOS, Linux, and Android, net-merge provides connection-level load balancing without requiring an account.
