Does FleetBar require installing any software or agents on my remote servers?

No. FleetBar is completely agentless. It connects securely over standard SSH using non-interactive batch mode and standard POSIX shell commands, meaning your servers remain clean with zero extra daemons.

Does FleetBar support Apple Silicon M1, M2, M3, and M4 Macs?

Yes, FleetBar is a native Swift application optimized for Apple Silicon (M1/M2/M3/M4) as well as Intel Macs running macOS 13.0 (Ventura), macOS 14 (Sonoma), and macOS 15 (Sequoia).

Can FleetBar monitor and restart Docker containers?

Yes! FleetBar auto-detects Docker on remote Linux servers and local environments (OrbStack, Docker Desktop). You can see container states, restart services, and jump directly into container exec shells with one click.

Everything you need. Zero bloat.

Built specifically for developers and sysadmins who value speed, privacy, and simplicity.

Agentless via SSH

No need to install binary agents, curl mystery bash scripts, or open inbound ports on your servers. FleetBar securely probes over standard SSH.

Docker Container Control & Shell

Detects Docker on remote servers and local OrbStack / Docker Desktop. Jump directly into any container with an interactive shell (`docker exec`), or restart services with 1 click.

1-Click SSH Terminal

Need to run a command? Click the terminal icon on any server to immediately pop open your favorite terminal (Terminal, iTerm2, Ghostty, Kitty) connected to that exact host.

How Agentless Monitoring Works

Zero overhead on your hosts. Complete control on your Mac.

01. Standard SSH Auth

Uses your existing Mac SSH configuration (`~/.ssh/config`) and keys (`id_ed25519`, `id_rsa`). Passwords are kept safely in your native macOS Keychain.

02. Lightweight POSIX Probing

Executes non-blocking POSIX shell commands (`vmstat`, `top`, `df`, `docker ps`). Consumes less than 0.1% CPU on both host and Mac.

03. Native Swift Presentation

Renders smooth, high-DPI Sparklines and gauges directly in the macOS menu bar with zero memory leaks or battery drain.
