The NodeTool desktop app is built on Electron. It reuses the web app for all workflow editing but adds a handful of native surfaces: a boot splash, install wizard, package manager, log viewer, tray menu, pinned windows, and a native menu bar.

This page catalogs every desktop-only view with screenshots. Everything inside the main window is covered by User Interface and Workflow Editor.


Boot Message (Splash)

A minimal splash appears while the embedded Python runtime, backend server, and web app all come online.

Boot Message

The splash streams progress messages — “Starting Python…”, “Warming models…”, “Connecting to server…”. It closes the moment the backend reports ready.


Install Wizard

On first launch (or after a major upgrade), the Install Wizard sets up the optional components NodeTool needs to run local models:

  • Conda environment with the required Python version
  • Node packs selected by the user
  • AI runtimes (torch, MLX, llama.cpp) appropriate for the detected hardware

Install Wizard

You can re-run the wizard at any time from the Package Manager window — useful when you add a new node pack or upgrade your GPU.


Package Manager

Opens from the app menu or ⌘K → Open Package Manager. A native window sized 1200×900 that manages:

  • Installed node packs and their upgrade availability.
  • Optional AI runtimes (torch CUDA, torch MPS, llama.cpp).
  • Conda environment health (Python version, cached wheels).
  • Integrity checks — re-download a broken runtime in one click.

Package Manager

See Node Packs for where packs come from and how to publish your own.


Log Viewer

A persistent window that tails the backend log. Helpful for debugging without dropping to a terminal.

Log Viewer

The log viewer supports:

  • Log level filtersdebug, info, warn, error.
  • Component filters — backend, Python worker, web bridge, IPC.
  • Search with regex and highlight.
  • Jump to file — click a line to open its source in your editor (if EDITOR is configured).

Update Notification

When a new desktop release is available, a discreet toast appears with Install now and Later actions. The app restarts into the new build; there’s no mandatory update interrupting a run.

Update Notification


Pinned Windows

Electron adds a few borderless, always-on-top window types:

Workflow Execution Window

A frameless window that runs a single workflow with the inputs collapsed and the outputs centered. Great for a pinned dashboard on a second monitor.

Workflow Execution Window

Mini-App Window

A self-contained Mini-App launched from the tray. Maximum size 1200×900. Closing it doesn’t quit NodeTool.

Mini-App Window

Chat Window

Standalone chat opened from the tray. Same content as /standalone-chat but in its own window.

Chat Window


System Tray

The tray icon stays running while NodeTool is active and exposes quick actions:

Tray Menu

Action What it does
Open Dashboard Bring up the main window
Open Chat Launch the standalone chat window
Run Mini-App… Submenu of mini-apps published from your workflows
Settings Native settings window
Package Manager Open the Package Manager window
Log Viewer Tail the backend log
Quit NodeTool Stop the backend and exit

Native Menu Bar

On macOS and Windows a native menu bar is attached to the main window.

Menu Bar

File

Item Shortcut Action
New Workflow Ctrl/⌘ + T Open a blank workflow in a new tab
Save Ctrl/⌘ + S Save the active workflow
Close Tab Ctrl/⌘ + W Close the active editor tab
Quit Ctrl/⌘ + Q Exit the app

Edit

Standard Undo, Redo, Cut, Copy, Paste, Select All, Delete — all mapped to the same shortcuts used on the canvas.

View

Item Action
Settings Open the native settings window
Package Manager Open the Package Manager window
Log Viewer Open the Log Viewer window
Reload Reload the main window
Toggle DevTools Useful for debugging custom node UIs

Window / Help

Platform-standard items — switch windows, open the docs, show version info.


Where the Electron Code Lives

For contributors:

  • electron/src/main.ts — entry point, window lifecycle.
  • electron/src/window.ts — main window.
  • electron/src/workflowWindow.ts — pinned workflow and mini-app windows.
  • electron/src/tray.ts — tray icon and menu.
  • electron/src/menu.ts — native menu bar.
  • electron/src/components/ — React components for the native windows.
