Core Tunnel5.1

Route SSH traffic through local, remote, or dynamic port-forwarding tunnels from one Mac workspace with Core Tunnel. It manages multiple SSH connections through an automatic interface designed for OpenSSH, so hosts and tunnels can be started, watched, and maintained in one place. Its feature set includes agent forwarding, certificate authentication, proxy jump, and other OpenSSH capabilities.

Core Tunnel can connect and monitor numerous tunnels at once, while macOS Keychain securely stores passphrases for those connections. Each host has editable advanced SSH options, and contextual help explains the available ssh directives as you configure them. The app attempts to restore connections after a network interruption or after the Mac wakes from sleep. Controls and tunnel status remain available without forcing you to leave the window where you are working.

Tags help organize installations containing hundreds or thousands of tunnels, making large host collections easier to navigate. Version 5.1,4874 runs on macOS 15 Sequoia or later and supports Intel and Apple Silicon Macs. Listed in Security & Privacy, Core Tunnel is freeware and also offers a Premium option for users who want its expanded offering.
