Adobe Substance Designer is described as 'Substance Designer is a node-based non-destructive application for material authoring. Edit complete texture sets fast with the non-linear workflow and see your changes apply simultaneously to all your outputs' and is an app in the photos & graphics category. There are more than 10 alternatives to Adobe Substance Designer for a variety of platforms, including Windows, Mac, Linux, Epic Games Store and Electron apps. The best Adobe Substance Designer alternative is Material Maker, which is both free and Open Source. Other great apps like Adobe Substance Designer are InstaMAT, Quixel Suite, TextureLab and PixPlant.
Material Maker is a free and open-source, procedural texture authoring tool based on Godot Engine. Its user interface is based on Godot's GraphEditor: textures are described as interconnected texture generators and operators.
InstaMAT offers a comprehensive solution for procedural material and asset creation, scalable texturing, and data-driven asset pipelines where instead of texturing a specific asset, you're now texturing an entire class of assets using a previously established workflow.

Quixel was founded in 2011 by Teddy Bergsman and Waqar Azim, based on the vision of substantially speeding up how creators build digital environments, by giving them access to a vast and ever-expanding library of 3D building blocks, and easy-to-use tools to greatly simplify the...
TextureLab is a tool designed to make procedural texture generation fast, simple and free. It is the first in a line of tools dedicated to make the process of making beautiful textures easy and artist-friendly.
PixPlant is a smart texturing app with the best tools to quickly transform a photo into seamless repeating textures and 3D maps.
Substance 3D Sampler is at the heart of your 3D workflow. Easily transform a real-life picture into a photorealistic surface or HDR environment.

PixaFlux is a node based image processing application. PixaFlux creates and edits images in a non destructive way, using a node graph to organize the workflow without restrictions of size, position or color mode.
FilterJS is a node-based procedural texture generator, meaning that you will compose your filter, generator, or algorithm to make a texture – you name it – out of special blocks. Each filter has two unique blocks: an input image and an output image.
JSplacement is pseudo-random 8K displacement map generator made with JavaScript on Electron. It generates grayscale height maps that can be used for dispacement (and many other things) in various 3D packages and reders. Or even with 3D fractals or various 2d works...
Graphics tool offering 6700+ free photo and video effects, procedural seamless textures, resolution up to 65000x65000px, 30,000 effect variations, PBR map export, node-based filter creation without coding, full preset management, and instant 3D compatibility.
It also has a node based system, and has an extensive library of textures. It also can add effects to existing images.
TexGraph is a procedural texture creation tool that let you create textures by connecting nodes in a graph. It is designed to be similar to other tools in the market but at the same time be very simple and easy to use and extent by users.

Definetely not as resource efficient as SD, and not a drop in replacement. But pretty much the only serious attempt to make an open source application similar to Designer Much better than trying to make something useful in Blenders Shader Nodes,
