Comfy Nodekit – build/serialize ComfyUI workflows in Python

In plain words

Comfy Nodekit is a Python library for building and exporting ComfyUI workflows programmatically. Instead of hand-crafting large JSON graphs, developers use typed node factories to create workflows in Python, then serialize them back to ComfyUI's expected format. It automatically generates Python bindings by introspecting a running ComfyUI server, including custom nodes, making it easier to manage and version complex workflows with hundreds of nodes.

Utilities for working with ComfyUI node graphs from Python. The project provides typed wrappers around ComfyUI nodes, lightweight graph primitives, and helpers for exporting a workflow back to the JSON format that the ComfyUI API expects. uv add comfy_nodekit # pip install comfy_nodekit Generate node bindings (required before usage) Before using the factory functions, generate nodes.py from your running ComfyUI: uv run python -m comfy_nodekit.nodes_to_py http://127.0.0.1:8188/ # or: just run If you omit the URL, it defaults to http://127.0.0.1:8188/ . This writes nodes.py based on the server's /object_info . Re-run whenever your ComfyUI nodes change. # From default server (same as before)…from github.com

In the maker’s words, at launch

Hello HN! I made Comfy Nodekit, a small library to make it easier to build and serialize ComfyUI workflows directly in Python. If you’ve ever tried to hand-craft large ComfyUI graphs or maintain JSON workflows by hand, you probably know how messy it gets once you reach a few dozen nodes. We needed a better way to…

  Open-source app builder for comfy workflows2024 · github.com · ▲59

  Hey, we’ve been working on an open-source project built on top of Comfy for the last few weeks. It is still very much a work in progress, but I think it is at a place where it could start to be useful. The idea is that you can turn a workflow into a web app with an easy-to-use UI. Currently, it should work with any workflows that take images and text as input and return images. We are aiming to add video support over the next few days. Feedback and contributions are more than welcome!

  Probly – Spreadsheets, Python, and AI in the browser2025 · github.com · ▲171

  Probly was built to reduce context-switching between spreadsheet applications, Python notebooks, and AI tools. It’s a simple spreadsheet that lets you talk to your data. Need pandas analysis? Just ask in plain English, and the code runs right in your browser. Want a chart? Just ask. While there are tools available in this space like TheBricks, Probly is a minimalist, open-source solution built with React, TypeScript, Next.js, Handsontable, Hyperformula, Apache Echarts, OpenAI, and Pyodide. It's still a work in progress, but it's already useful for my daily tasks.

  Hey all, I am Paul, an indie-dev, I am working on this web based Drag and drop GUI builder tool for python. It's still in beta and currently supports tkinter and customtk. It can generate clean code python for the UI you build. You can check out the source code here: https://github.com/PaulleDemon/PyUIBuilder Feel free to check it out. Thanks!

  Rubbrband – A hosted ComfyUI alternative for image generation2024 · ▲61

  Hey HN! My friends and I built a new platform for generating images. The app is easy to use for people who find ComfyUI hard to use, or just simply don’t have a GPU to use it on. For those not familiar, ComfyUI is a great tool for using open-source models like Stable Diffusion. It’s primarily great because it’s a node-based tool, which means you can chain together models, upscalers, prompting nodes, etc… which let you create images in the exact aesthetic you want. There’s also a vibrant dev community behind ComfyUI, which means that there are a ton of nodes and customizability. We’re users…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Strange Attractors▲804

  I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

  Autism Simulator▲779

  Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
