DESKTOP APP

Get Fleet Runner

FleetCrown runs in your browser as a full control plane. Fleet Runner is the optional desktop app that lets agents act on your computer — open files, run commands, drive terminal sessions — while you stay in command from the web or your phone.

Web (fleetcrown.com)
Already available — no install
  • Full fleet visibility across all projects
  • Browse history, projects, and queues
  • Dispatch commands from any browser or phone
  • Read-only without a connected local runner
Desktop (Fleet Runner)
Adds local execution
  • Actually runs agents on your machine
  • Drives Zellij sessions and handoffs
  • Native notifications when an agent finishes
  • Keeps working after you close your browser

You can start with the web today and add Fleet Runner whenever you want agents to actually do work on your machine.

Download .deb (Ubuntu / Debian / Mint)(Recommended · ~80 MB · installs via package manager)
AppImage (other distros)
Open a terminal and paste this one line. It installs Fleet Runner system-wide, then launches it. No file-manager dance, no KDE security popup:
sudo dpkg -i ~/Downloads/Fleet-Runner-linux-amd64.deb && fleet-runner
After install
01
Make it runnable, then open

On Linux, downloads start non-executable for safety. Paste the one-line command shown under Download to mark Fleet Runner executable and launch it. On macOS and Windows (coming soon), a normal double-click is enough.

02
Sign in — once

Use the same FleetCrown account you signed up with on the web. The desktop app opens straight to your dashboard. From the web, you can also click "Open in Fleet Runner" to log the desktop app in without copy-pasting a token. From v0.3.0 onward, Fleet Runner checks for updates on launch and downloads them in the background — you'll never have to manually re-download.

03
Dispatch your first intent

Pick a project on your computer and dispatch an intent. Fleet Runner launches the agent in a terminal session and pings you when it hands off — even if the app is hidden. The terminal session manager ships inside Fleet Runner; you just need at least one agent CLI installed (Claude Code or Grok — see prerequisites below).

What Fleet Runner uses on your computer

Fleet Runner doesn't replace the tools you already use — it drives them. Only one thing must exist on your machine for an agent to actually run: a supported agent CLI. Pick whichever AI you prefer; you only need one to start. (Zellij — the terminal session manager that gives each agent its own pane — ships inside Fleet Runner since v0.2.0, so you no longer install it separately.)

Claude Code
Anthropic's coding agent
Required

One supported agent CLI is required — Claude Code is the recommended default. Skip this if you already plan to install Grok below; you only need one.

npm install -g @anthropic-ai/claude-codeInstall Claude Code
Grok Build
xAI's coding agent
Optional

Alternative agent CLI. Install instead of Claude Code, or alongside it if you want both available to the fleet.

curl -fsSL https://x.ai/cli/install.sh | bashInstall Grok CLI
Zellij
Bundled — no install needed
Optional

Fleet Runner v0.2.0+ ships with a known-good Zellij inside the bundle and prefers it over any system install. Listed here only so you know what's running. Install it yourself only if you also want a system-wide Zellij outside Fleet Runner.

Zellij docs (optional)

The desktop app, the web, and your phone all connect to the same fleet. Use whichever surface is in front of you.
