xNormal is described as 'Application to generate normal / ambient occlusion / displacement maps. It can also project the texture of the highpoly model into the lowpoly mesh ( complete texture transfer, even with different topologies )' and is an app in the photos & graphics category. There are nine alternatives to xNormal for Windows, Linux, Mac, Epic Games Store and GIMP. The best xNormal alternative is Quixel Suite, which is free. Other great apps like xNormal are AwesomeBump, Crazybump, Resynthesizer and HandPlane Baker.
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...
AwesomeBump is an open source program designed to generate normal, height, specular or ambient occlusion textures from a single image. Since the image processing is done in 99% on GPU the program runs very fast and all the parameters can be changed in real time.
Crazybump generates lighting maps from 2D textures. It supports ambient occlusion (AO) maps, bump maps, normal maps, and more.
This is a suite of ten Gimp plugins known as the 'Resynthesizer'. The most commonly used is 'Heal selection' but all use the plugin whose full interface is found at 'Filters>Map>Resynthesize.
Handplane Baker is a free baking tool for a production environment that processes extremely dense models easily.
NVIDIA Melody creates high quality normal maps that make a low-poly model look like a high-poly model. Simply load your low-poly working model, then load your high-poly reference model, click the "Generate Normal Map" button and watch Melody go to town.
MindTex is a normal map generation utility for game developers and 3d professionals. Built to rival the competition in quality without the steep price, whether you want to generate a normal, height, specular, gloss, self-illumination, occlusion, or reflection map, you can easily...
Mightybake is fast hybrid GPU / CPU accelerated baker maximizes your hardware to bake textures ultra fast.
ModLab is a free tool that can generate and fine tune normal maps in a realtime rendering environment.

Quixel suite was made to texture 3D objects, while XNormal was made to bake High Poly models into lowpoly textures. While Quixel has recently added certain baking it doesn't do it for highpoly to lowpoly and as such the major use of the two programs are far from similar.
