Wonderful Launcher Quick Start

Use this guide when you are opening Wonderful Launcher for the first time and want the shortest path into a working ComfyUI workspace.

What this guide covers

• choosing between Deploy and Import
• starting ComfyUI from the Home page
• checking startup progress
• opening the embedded Workspace

Before you start

You need Wonderful Launcher installed on Windows. If you already have a ComfyUI folder, keep it available so you can import it instead of deploying a fresh package.

Deploy vs Import: which should I pick?

Step 1: Open the Home page

When the app opens, stay on Home. This is where you choose the active ComfyUI package and start the runtime.

Step 2: Choose Deploy or Import

Use Deploy when you want Wonderful Launcher to install a managed ComfyUI package for you.

Use Import when you already have a local ComfyUI folder and want the launcher to manage it.

Step 3: Start ComfyUI

Click Get Started or the main start button on Home. The launcher starts ComfyUI and shows progress in the app instead of leaving you to read a separate terminal.

Step 4: Open Workspace

When ComfyUI is ready, open Workspace from the bottom bar. The ComfyUI web interface appears inside the launcher.

What success looks like

When ComfyUI has fully started, you will see:

• The Home page shows a green running indicator next to the active package.
• The Workspace tab in the bottom bar becomes active and clickable.
• Inside Workspace, the ComfyUI node editor loads with the default workflow (or your last-used workflow).
• No red error banners appear at the top of the Home page.

If startup fails

Open the logs first. Copy the visible error message, then use Agent or the related troubleshooting guides to repair the environment.

• ComfyUI startup failed
• ComfyUI plugin import failed
• Dependency conflicts

Where to find logs

If something goes wrong, logs are the fastest way to diagnose:

1. In-app log panel — on the Home page, expand the log area below the start button to see real-time output from ComfyUI.
2. Log files on disk — Wonderful Launcher writes log files to the logs folder inside each ComfyUI package directory. Look for the most recent .log file.
3. Windows Event Viewer — for crashes that prevent the launcher itself from starting, check Application logs in the Windows Event Viewer.

Beginner FAQ

Can I run multiple ComfyUI packages at the same time?

No. Wonderful Launcher runs one ComfyUI instance at a time. You can switch between packages by stopping the current one and starting another from the Home page.

Do I need a GPU?

A dedicated NVIDIA GPU with at least 4 GB VRAM is strongly recommended. ComfyUI can run on CPU, but image generation will be extremely slow. AMD GPU support is experimental.

How do I update ComfyUI after deploying it?

Use the package management features on the Home page. The launcher can update ComfyUI and custom nodes in place without losing your models or workflows.
