Apps similar to NVIDIA Melody include AwesomeBump, which is free and open source. Other options are Quixel Suite, Laigter, xNormal and Resynthesizer. You can choose from more than 10 Game Development Tools like NVIDIA Melody for Windows, Linux and Mac.
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.
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...

This tool lets you generate normal maps for 2D textures, with little effort. Specially designed for Sprites in 2D games.
xNormal is an 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 ).
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.
SpriteIlluminator lets you easily generate normal maps for your 2d game and web projects. Render dynamic lighting & other effects and use paint tools to directly draw on the normal map and fine tune the effects.
Sprite Lamp is a software tool to help game developers combine 2D art with dynamic lighting effects, through the creation of hand drawn normal maps.

Knald is the world’s first GPU powered solution for generating “bake quality” textures from any 2D source texture.
Handplane Baker is a free baking tool for a production environment that processes extremely dense models easily.
Mightybake is fast hybrid GPU / CPU accelerated baker maximizes your hardware to bake textures ultra fast.
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...
Sprite Bump is an advanced 2D Normal Map Generation Tool. It takes in a single 2D image and generates a normal map and optional ambient occlusion map for use in 3D Lighting for realtime Game Engines ( Unreal Engine, Unity etc.
