How to make your own custom ComfyUI nodes

[@patMacom]

Coming from over 2 decades of coding - I have to say that you have one of the best (and accurate) perspectives on coding that I've come across in a long while. Appreciate you greatly

[@codysoftware]

Thank you!

[@HistoryIsAbsurd]

I like the small bit at the start where you gave tips and encouragement. Im only a few months into it and little hints like that really do help.

[@Foolsjoker]

I would love to see break downs of what the existing nodes actually do. Like going through its code and seeing their input to output explained. Might help gear some ideas on what we could customize, or modify ourselves.

[@codysoftware]

Great idea! I'll add this to my list :)

[@done.6191]

Really liking this so far. I’ve reached the point where I have such specific node needs that only custom can do it. I’ve started small and cobbled together some small nodes but trying to level up. Thanks!

[@sidheart8905]

I have been doing my own nodes in my local, but i find your video still good, thanks a lot for taking efforts for the video... i am too lazy to make something like this, hope you get lots of views and subscribers :)

[@Vhourgannox]

Thanks loads for this tutorial. This is literally the only coherent explanation I could find on how to make a custom node. I've taken an introductory python class, so I've written some code myself and even made a couple of really basic one-file programs (mostly just complicated specialized calculators), but trying to decipher the example_node.py.example just gave me a headache. I couldn't figure out what the code was doing because I didn't know what ComfyUI was doing outside of that one file, and following the directions in the example was like trying to have a conversation in Spanish after spending a month using Duolingo; I could vaguely see what it was supposed to do in some chunks, but I was missing important pieces and couldn't put the whole thing together. I still don't feel like I can breeze through this, but I definitely feel like you've given me enough of a shove in the right direction that I can probably get it to do what I want with some experimentation. I also never knew GPT could give me coding advice, so I'm definitely going to use that now. Thanks again man.

[@codysoftware]

I'm glad you found the video helpful! You're exactly the type of person I'm looking to help with my videos. Let me know what else you'd like to see!

[@swannschilling474]

That is really nice!! So little on this is out there!! 😊

[@MetalMakeover]

I have something useful for you to use your programming skills to produce, a GUI for making CompyUI custom nodes. Whoever made Comfy should have made one but they didn't. You should be able to bring up a blank node and then have a thing for putting inputs and outputs on it and titling the node and labeling the various parts by simply typing them into a box, and eventually exporting the node as a package. There's a program called Channer, which seems to be what Comfy was based on. In Chainner you can browse to, and load into a node, models in different formats, like pth, onnx and ones that have param and bin sets, like in RealESRGAN portable. You can't do that in Comfy, to my knowledge. I can't load a RealESRGAN model into Comfy but I can in Chainner, I'd like to have a Comfy node to do that. How could a Chainner node be "ported", or whatever you would call it, over to being a Comfy node? That would be a handy converter to have. You can do a lot of things in Chainner, it's a very extensive image program. What you could do is make GUI that looks like Chainner, or Comfy, but it's just a node editing GUI. Something about Chainner, it's not on a web browser, it has its own screen.

Nice video thank you for taking the time to do this.

[@daniel99497]

Good tutorial, do more !

[@codysoftware]

I'm thinking about it! What would you like to learn?

[@daniel99497]

@@codysoftware The struggle iam having right now is dealing with masks image torch tensor compatibilities , how to convert np to tensor in a way that is expected, what outputs are expeted of IMAGE or MASK that whats stopping me the most on creating nodes, i never know the best aproach

[@basementadmin]

Thank you. Great stuff

[@TheMaxvin]

You are well done. Where should I put the my file(new node) itself so that the Comfy can take it?

[@gordonbrinkmann]

Nice, maybe I'll make some custom nodes now. So far I've just edited some existing ones to my liking. By the way George Boole was of course an Englishman as the name already suggests, not a French guy.

[@codysoftware]

So he was - I stand corrected!

[@brothachris]

Great tut! Thanks :)

[@reginaldli5218]

how can I call other developed nodes by community in my own node scripts?

[@impactframes]

Good video. Thank you

[@Clupea101]

Great Insight

[@certainframe]

Thanks Cody. Very good tutorial. Any idea how to attach a debugger from VScode and set breakpoints?

[@certainframe]

I’m trying to step through some comfyui code to understand how it works

[@codysoftware]

That's a very good question! It looks like it's theoretically possible. I'll add that to my list of videos to work on :)

[@GREATMAGICIANLYNEY]

I believe this is going to be very helpful to me when I start digging into it-- Thank you! This question misses the point of your broader message entirely, I understand, but I tried to use the node you created and realized that my latent image node does not have a height or width inputs. Am I using the wrong latent image node, or has ComfyUI updated since you created this video three weeks ago? Not a huge issue as it is, like I say, tangential to your broader purpose, but I just found that curious.

[@codysoftware]

ComfyUI hasn't updated significantly since the video came out, so it sounds like the "Empty Latent Image" node should be the one you're looking for. Make sure the one you're using is the same one described in the community manual here: blenderneko.github.io/ComfyUI-docs/Core%20Nodes/Latent/EmptyLatentImage/

[@GREATMAGICIANLYNEY]

@@codysoftwareThank you Cody

[@xiaozhengwu5780]

could you post your code? thanks!

Added to the description

[@yadav-r]

Can you please teach us how to download image from ComfyUi using api.

[@ultimategolfarchives4746]

You can find a pretty str8nforward exemple in the project. Just follow it. /comfyui/script_exemples/basic_api_exemple.py

[@zablok69]

looking for someone to write custom nodes for me - paid.

[@wgxyz]

Hey i was wondering if its possible for us to lock comfyui nodes with an activation license? Anyone interested in building this for me hit me up

[@dflfd]

dude, its an open source project. doubtful that you can hide the source. plus it goes against the community spirit. might even violate the license.

[@makadi86]

thank you very much but plz next time define the people you are talking to, making a video for both programmers and non programmers is not a good idea at all. it will be very boring for programmers, and very hard to non programmers.

[@11704187]

Put it in your custom_nodes directory! 8:18

[@AIAngelGallery]

thank you so much, i was trying to find way develop my own custom nodes and i found this clip. perfect for me

[@buxsin]

hi Cody.. you need a better microphone. whatever rode mics would be fine... Since i am interested in coding i am subscribing to suport you...Good luck with your streams... ❤❤🌹🌹

[@codysoftware]

I got a new one! Check out my more recent videos and tell me how I sound :)

[@Luxcium]

8:30 ok but I am on my mobile phone and 😮😮😮😮

[@xueqinghuang5021]

great tutor for comfyui nodes, thx!

[@robinhahn6987]

Thanks for this, Cody... I've been wanting to sort cobble my own for a while now, but didn't know where to start. You showed not only where to look but how to nut out what you're looking at. I've written custom stuff for Blender so some of this was basic, but I did watch it all the way through because you did such a good job explaining stuff. That @classmethod stuff also exists in Blender and I never really figured out what it was, exactly. Thanks again - hope you make more videos! Subscribed 😊

[@robinhahn6987]

BTW, I noticed others were also asking for more videos on custom node development. I haven't had much of a look at ComfyUI's API, but I'm sure there are libraries to import (noticed you imported 'math') that would give rise to explaining how to read APIs, for example, in order to take advantage of those libraries. Dunno - would that be a bit advanced, maybe? Personally, I want to do conditional switches - I know, they already exist, but still. Python is such an awesome language - the possibilities are limitless! 😮

[@aylictal]

@@robinhahn6987 math isn't a part of comfyui, its a library you can include from python itself.

[@blender_wiki]

Great content, highly raccomented tutorial. However if you are already a programmer you must listen to this at 2x because it is a bit too "for beginners"

[@falconbmstutorials6496]

4:00 that's very kind and encouraging! I appreciate that! You need to explain that the initial file inside a custom node folder should be named "__init__.py" else it will not be recognized by ComfyUI
