## Overview

Not all nodes are built the same. In Floyo, you can use both core nodes and custom nodes in any workflow. Understanding the difference helps you build more effectively.

***

## Types of Nodes

| Node Type        | Source                   | Availability                           |
| ---------------- | ------------------------ | -------------------------------------- |
| **Core Nodes**   | Built into ComfyUI       | Always available                       |
| **Custom Nodes** | Community or third-party | 2,500+ pre-installed; more added daily |

***

## Core Nodes

Core nodes are the default set that comes with ComfyUI. These are the basics, the essential tools that power almost every workflow.

### What Core Nodes Include

| Category                    | Examples                             |
| --------------------------- | ------------------------------------ |
| **Model loaders**           | Load Checkpoint, Load LoRA, Load VAE |
| **Samplers and schedulers** | KSampler, KSamplerAdvanced           |
| **Prompt inputs**           | CLIP Text Encode, Conditioning       |
| **Image outputs**           | Save Image, Preview Image            |
| **Conditioners**            | ControlNet Apply, Apply LoRA         |
| **Upscalers**               | Upscale Image, Upscale Latent        |
| **Image processing**        | Resize, Crop, Combine, Mask          |

Core nodes are stable, well-supported, and usually all you need for common workflows. If you've used ComfyUI before, you'll recognize them right away.

## Custom Nodes

Custom nodes come from the broader ComfyUI community or your own team. These extend what you can do far beyond the basics.

### What Custom Nodes Can Do

| Use Case                     | Examples                                        |
| ---------------------------- | ----------------------------------------------- |
| **Specialized LoRA loaders** | Advanced LoRA stacking, conditional loading     |
| **Custom samplers**          | Alternative sampling algorithms                 |
| **Text tools**               | Logic gates, advanced math, string manipulation |
| **Animation & UI**           | Control nodes for scripting and batch workflows |
| **Non-image tasks**          | Audio, data processing, function chaining       |

Floyo supports over **2,500 custom nodes**, and you can load your own too. If someone has built it and shared it, you can use it.

**💡 Tip:** Custom nodes are what make ComfyUI so powerful. They let the community solve problems faster than any single team could.

## Using Core and Custom Nodes Together

You can mix core and custom nodes freely. Most advanced workflows use a combination of both.

- You don't need to know where every node comes from
- If it works, it works
- Hover over a node for a tooltip or inspect its inputs and outputs

Floyo makes it easy to experiment without breaking your flow.

***

## Missing Custom Nodes

If you're loading a workflow with custom nodes not currently installed on Floyo:

1. A message is sent to Floyo's developers
2. The team works to install the missing nodes
3. Official turnaround time: **within 72 hours**
4. In practice, it's usually much faster

You can also proactively request custom nodes. See [Requesting Custom Nodes](https://docs.floyo.ai/requesting-custom-nodes) for details.

## How to Tell the Difference

In most cases, you don't need to distinguish between core and custom nodes. However, if you're curious:

| Indicator                     | Meaning                                                         |
| ----------------------------- | --------------------------------------------------------------- |
| **Node pack name in browser** | Custom nodes show their pack name (e.g., "ComfyUI-Impact-Pack") |
| **Missing node errors**       | Usually indicates a custom node that needs installation         |

***

## Tips & Best Practices

- **Start with core nodes:** Learn the basics before diving into custom nodes
- **Explore custom packs:** Browse installed custom node packs to discover new capabilities
- **Check compatibility:** Custom nodes may have dependencies on specific models or other nodes
- **Request what you need:** If a workflow requires a missing node, Floyo will install it for you
