[!WARNING]
While the core functionality is operational, some features from the Python version are still being implemented. The framework is actively developed and aims to eventually match the full capabilities of the official ComfyUI node system.

Quick Start

Start from this template: comfy-builder-template

Overview

ComfyUI Node Builder provides a powerful, type-safe framework for creating custom nodes in ComfyUI using Rust.

Built with performance in mind, this framework offers faster execution times and a more streamlined development experience compared to traditional Python-based node development.

Quick Start

Basic Node Example

use comfyui_plugin::prelude::*;

#[derive(NodeInput)]
pub struct Input {
    a: usize,
    b: usize,
}

#[derive(NodeOutput)]
pub struct Output {
    sum: usize,
}

#[node(
    category = "MyNode / Math",
    description = "Sums a + b inputs."
)]
pub struct Sum;

impl<'a> Node<'a> for Sum {
    type In = Input;
    type Out = Output;
    type Error = Box<dyn Error + Send + Sync>;

    fn execute(&self, input: Self::In) -> Result<Self::Out, Self::Error> {
        Ok(Output {
            sum: input.a + input.b
        })
    }
}

boostrap!(api_version: "latest");
