RelayBar

RelayBar is a tiny native macOS menu-bar app for structured SSH forwarding profiles and exact-path remote file access. It runs macOS's built-in /usr/bin/ssh and /usr/bin/sftp directly.

What it does:

• Imports repeated and mixed -L, -D, and -R rules from forwarding-only SSH commands
• Supports TCP ports, Unix sockets, local SOCKS, reverse SOCKS, and automatic remote ports
• Runs every rule in a profile over one managed SSH connection
• Optionally groups saved profiles into lightweight menu-bar sections
• Starts and stops each profile with one click
• Opens an unambiguous local TCP forward in the default browser with one click
• Retries unexpected disconnects up to 10 times with exponential backoff
• Shows startup failures directly beside the tunnel
• Stores tunnel definitions in local UserDefaults
• Stops child SSH processes when RelayBar quits
• Opens an exact remote folder from a pasted absolute path and saved server
• Downloads remote files or folders with progress, cancellation, and Finder reveal
• Previews supported remote images without adding editing or gallery features
• Renders remote Markdown in a safe, read-only view with GFM, callouts, inert tags, syntax highlighting, footnotes, and native math
