Core Shell vs SecurSSH

Core Shell is a terminal app for managing hosts and opening remote shells with built-in OpenSSH support. It supports remote sessions, certificates and proxy jump, and the maker says a remote host can be reached with one click. Tags help organize large host lists, while per-host advanced SSH options come with contextual help. The app integrates with macOS Keychain for passphrases and can try to restore connections after network failure or waking from sleep. It also supports USB, Bluetooth and built-in serial interfaces, with common UART, RS-232, RS-422 and RS-485 adapters. Its terminal supports Terminal.app, iTerm2 and xterm compatibility and ANSI 16-color, 256-color and 24-bit color modes. SFTP is supported, and sessions use tabs. The free Basic plan allows unlimited hosts. Premium costs $29.99 a year, billed as a 4-Year License, and adds unlimited SSH and serial connections, profile importing and exporting, profile and tag sync across Macs, Shortcuts automation and priority support. It is listed for Mac, iPhone and iPad; macOS 15.0 or later is specified.
