Speedify

About

Speedify is channel bonding software for macOS that combines Wi-Fi, 4G/5G, Ethernet, Starlink, and satellite connections into a single connection that is faster, steadier, and encrypted. Normally a device can use only one internet connection at a time, even when several are available. Speedify lets it use every connection at once, so you get their combined speed and stay online if one drops out. Automatic failover reroutes traffic to the remaining links in milliseconds.

Speedify works with any mix of connections, including several of the same kind at once, and combines them with up to 95% of their combined throughput. It gives real-time apps such as Teams, Zoom, and OBS priority over other traffic. You can set each connection as primary, secondary, backup, or never, and add data limits so metered links like cellular are used only when you want. Its Pair & Share feature lets two devices share cellular connections with each other, adding paths without extra hardware.

Every link runs through an AES-256 encrypted tunnel under a strict no-logs policy. The company states that its security is independently audited and verified through regular third-party review.
