PortButler

PortButler is a macOS application that combines SSH, SFTP, and serial communication into a single window, offering a terminal, file manager, and serial monitor. It features faster file transfers than traditional clients, insightful error messages for connection issues, session persistence with tunnels, command snippet saving, and integrates with SSH keys and config without overwriting files. It supports multiple transfer protocols, remembers typed lines per session, and is designed for engineers working with devices and embedded boards. It runs natively on macOS 13+ with Apple silicon and Intel and comes with a 14-day free trial followed by a one-time $29 purchase.
