# Nexus Shell

> A native SwiftUI workspace for SSH, SFTP, Docker, SSH key management, and live server monitoring on Apple Silicon Macs running macOS 14.2 or later.

Nexus Shell provides a perpetually free tier for personal, non-commercial SSH use and a one-time lifetime Pro purchase with no subscription or automatic renewal. Install it with `brew install --cask viewer12/tap/nexus-shell` or download the signed and notarized DMG from the official website.

The app is local-first. Saved credentials and private keys are not exposed to the optional AI assistant or Agent Bridge. Agent Bridge is available only in direct-download and Homebrew builds; it is not included in TestFlight or Mac App Store builds.
