# ComfyUI-KikoTools ![License](https://img.shields.io/badge/license-MIT-blue.svg) ![Python](https://img.shields.io/badge/python-3.8%2B-blue.svg) ![ComfyUI](https://img.shields.io/badge/ComfyUI-compatible-green.svg) ![Tests](https://github.com/ComfyAssets/ComfyUI-KikoTools/workflows/Tests/badge.svg) ![Code Quality](https://github.com/ComfyAssets/ComfyUI-KikoTools/workflows/Code%20Quality/badge.svg) > A modular collection of essential custom ComfyUI nodes missing from the standard release. ComfyUI-KikoTools provides carefully crafted, production-ready nodes under the "ComfyAssets" category. Each tool is built with clean interfaces, thorough testing, and optimized performance for SDXL and FLUX workflows. This project started out of frustration with keeping ComfyUI up to date and waiting for dozens of custom nodes to update—most of which I didn’t even use. After taking a hard look at my workflow, I realized I only needed one or two features from these nodes, many of which were abandoned or stuck in maintenance mode. I tried forking, patching, and submitting merge requests, but eventually decided to create my own curated collection of tools—fully supported and maintained by me. That’s how Kiko’s Tools was born. I’m sharing them here with the community, and I hope you find them as useful as I do. ## 🚀 Features ### ✨ Current Tools | Tool | Description | Category | |------|-------------|----------| | [📐 Resolution Calculator](#-resolution-calculator) | Calculate upscaled dimensions with model optimization | 🖼️ Resolution | | [📏 Width Height Selector](#-width-height-selector) | Preset-based dimension selection with visual swap | 🖼️ Resolution | | [🎲 Seed History](#-seed-history) | Advanced seed tracking with interactive history | 🌱 Seeds | | [⚙️ Sampler Combo](#️-sampler-combo) | Unified sampling configuration interface | 🌀 Samplers | | [📦 Empty Latent Batch](#-empty-latent-batch) | Create empty latent batches with preset support | 📦 Latents | | [💾 Kiko Save Image](#-kiko-save-image) | Enhanced image saving with popup viewer | 💾 Images | | [📋 Display Text](#-display-text) | Smart text display with prompt detection | 👁️ Display | | [🤖 Gemini Prompt Engineer](#-gemini-prompt-engineer) | AI-powered image analysis and prompt generation | 🧠 Prompts | | [🔍 Display Any](#-display-any) | Universal debugging tool for any data type | 👁️ Display | | [🖼️ Image to Multiple Of](#️-image-to-multiple-of) | Adjust dimensions to multiples for compatibility | 🖼️ Resolution | | [📉 Image Scale Down By](#-image-scale-down-by) | Scale images down by a factor with quality preservation | 🖼️ Resolution | | [🎬 Film Grain](#-film-grain) | Add realistic film grain effects to images | 💾 Images | | [🔤 Embedding Autocomplete](#-embedding-autocomplete) | Smart autocomplete for embeddings, LoRAs, and tags | 🔧 Utils | | [🧹 Kiko Purge VRAM](#-kiko-purge-vram) | Intelligent VRAM management with detailed reporting | 🛠️ Utils | | [📂 Local Image Loader](#-local-image-loader) | Visual gallery browser for local media files | 💾 Images | | [🌐 Model Downloader](#-model-downloader) | Download models from CivitAI, HuggingFace, and custom URLs | 🛠️ Utils | | [⏱️ Workflow Timer](#️-workflow-timer) | Real-time execution timer with customizable display | 🛠️ Utils | ### 🧰 xyz-helpers Tools Advanced parameter management tools adapted from [comfyui-essentials-nodes](https://github.com/cubiq/ComfyUI_essentials) (now in maintenance mode): | Tool | Description | Category | |------|-------------|----------| | [🎛️ Flux Sampler Params](#️-flux-sampler-params) | FLUX-optimized parameter generator with batch support | 🧰 xyz-helpers | | [📁 LoRA Folder Batch](#-lora-folder-batch) | Batch process multiple LoRAs from folders | 🧰 xyz-helpers | | [📊 Plot Parameters](#-plot-parameters) | Visualize parameter effects with graphs | 🧰 xyz-helpers | | [🎯 Sampler Select Helper](#-sampler-select-helper) | Intelligent sampler selection with recommendations | 🧰 xyz-helpers | | [📅 Scheduler Select Helper](#-scheduler-select-helper) | Optimal scheduler selection for samplers | 🧰 xyz-helpers | | [✍️ Text Encode Sampler Params](#️-text-encode-sampler-params) | Combined text encoding and parameter management | 🧰 xyz-helpers | #### 📐 Resolution Calculator Calculate upscaled dimensions from image or latent inputs with precision. -

Please see [CONTRIBUTING.md](CONTRIBUTING.md) for guidelines. ### Development Principles - **KISS**: Keep It Simple, Stupid - **Separation of Concerns**: Clear module boundaries - **DRY**: Don't Repeat Yourself - **SOLID**: Object-oriented design principles - **TDD**: Test-driven development ### Reporting Issues Please use GitHub Issues with: - ComfyUI version - Tool/node name - Expected vs actual behavior - Minimal reproduction steps - Error logs if applicable ## 📄 License MIT License - see [LICENSE](LICENSE) file for details. ## 🏷️ Tags `comfyui` `custom-nodes` `image-processing` `ai-tools` `sdxl` `flux` `upscaling` `resolution` `batch-processing` `model-downloader` `civitai` `huggingface` `python` `pytorch` ## 🔗 Links - **ComfyUI**: [https://github.com/comfyanonymous/ComfyUI](https://github.com/comfyanonymous/ComfyUI) - **Documentation**: [examples/documentation/](examples/documentation/) - **Example Workflows**: [examples/workflows/](examples/workflows/) - **Issue Tracker**: [GitHub Issues](https://github.com/ComfyAssets/ComfyUI-KikoTools/issues) ## 📈 Stats - **Nodes**: 21 (15 core tools + 6 xyz-helpers) - **Features**: Embedding Autocomplete (settings-based, not a node) - **Categories**: 9 emoji-based categories for better organization - **Download Platforms**: 3 (CivitAI, HuggingFace, Custom URLs) - **Format Support**: 3 (PNG, JPEG, WebP with advanced controls) - **Presets**: 26 curated resolution presets - **Interactive Features**: 8+ (swap buttons, history UI, popup viewers, parameter visualization) - **AI Integration**: Gemini API with 40+ model support - **Test Coverage**: 100% (470+ comprehensive tests) - **Python Version**: 3.8+ - **ComfyUI Compatibility**: Latest - **Dependencies**: Minimal (PyTorch, NumPy, Pillow, google-generativeai for Gemini) ## 🙏 Attribution ### xyz-helpers Tools The xyz-helpers collection was adapted from [comfyui-essentials-nodes](https://github.com/cubiq/ComfyUI_essentials) by cubiq. The original project is in maintenance-only mode, and we've adopted these essential tools to ensure continued support and compatibility with modern ComfyUI workflows. We're grateful for cubiq's original work and contributions to the ComfyUI community. The following tools are based on comfyui-essentials-nodes: - Flux Sampler Params - LoRA Folder Batch - Plot Parameters - Sampler Select Helper - Scheduler Select Helper - Text Encode Sampler Params All adaptations maintain compatibility while adding new features and optimizations for the ComfyAssets ecosystem. ---
