FleetCode

A desktop terminal application for running multiple CLI coding agents simultaneously, each in isolated git worktrees.

Features

- Multiple Sessions: Run multiple coding agent sessions (Claude, Codex) in parallel
- Git Worktree Isolation: Each session runs in its own git worktree, keeping work isolated
- Persistent Sessions: Sessions persist across app restarts with automatic resumption
- Terminal Theming: Choose from preset themes (macOS Light/Dark, Solarized Dark, Dracula, One Dark, GitHub Dark)
- Setup Commands: Configure shell commands to run before the coding agent starts
- MCP Server Management: Add and configure Model Context Protocol (MCP) servers
- Session Management: Rename, close, and delete sessions with automatic worktree cleanup

Prerequisites

- Node.js 16+
- Git
- Claude CLI (npm install -g @anthropic-ai/claude-cli) or Codex

How It Works

Session Creation

1. Select a project directory (must be a git repository)
2. Choose a parent branch for the worktree
3. Select your coding agent (Claude or Codex)
4. Optionally add setup commands (e.g., environment variables, source files)
5. FleetCode creates a new git worktree and spawns a terminal session

Session Management

- New Sessions: Use --session-id  for first-time Claude sessions
- Reopened Sessions: Automatically resume with --resume
- Worktrees: Each session gets its own isolated git worktree
- Persistence: Sessions are saved and can be reopened after closing the app

Terminal Settings

Access settings via the gear icon (⚙️) in the sidebar:

- Font Family: Choose from common monospace fonts
- Font Size: Adjust terminal text size
- Theme: Select from preset color themes
- Cursor Blink: Toggle cursor blinking
