NN-custom-nodes

Also available in ComfyUI Manager.

A collection of utility nodes for ComfyUI focused on workflow optimization, image processing, resolution handling, and prompt generation.

Features:

• Execution Profiler

Tracks node execution times, displays timing badges in the UI, detects slow nodes, supports subgraph timing, and provides real-time performance events.

• Resolution Tools

Calculate, scale, and optimize image/video resolutions with aspect ratio support, pixel targets, orientation handling, and model-friendly dimension alignment.

• Wildcard Processor

Advanced prompt expansion system with random selections, weighted choices, wildcard files, nested paths, variables, reusable templates, seed-based reproducibility, LoRA cleanup, and comment support.

• Image Processing

Includes CAS sharpening, cropping, resizing, upscaling, color range adjustment, brightness/contrast/color controls, reference contrast matching, image grids, optimization, and preview fallback tools.

• Video Tools

Generate video timelines/contact sheets and calculate video dimensions and frame counts from resolution, aspect ratio, duration, and FPS.

• Image Saver

Advanced image output with PNG/JPEG/WebP support, batch saving, metadata preservation, automatic filenames, transparency support, quality controls, and filename placeholders.

• Workflow Utilities

Path parsing, cache cleanup, input validation, boolean switching with lazy evaluation, and other helper nodes.

Configuration:

Supports global settings through settings.toml for wildcard behavior and execution profiler options.
