Rock 3
Rock 3 is a procedural world generator to build believable and interesting earth-like worlds. By modeling tectonics and climate it drastically simplifies the process of building detailed and realistic biomes across continents and islands, while providing the controls you need to fine-tune and customize near-infinite possible planets. Save your worlds as equirectangular projections of biomes, elevation, heightmap, heat, water, and landmasses.
Rock 3 generates planets entirely on your GPU. It’s not recommended to run this on a laptop or other device with integrated graphics. Your experience may also be compromised on an old or low-end graphics card. In some cases scaling the resolution of the planet down can improve performance to usable levels. Maps are always saved at the highest resolution.

This new tectonics update has made Rock 3 the best map generator/simulator avaliable by FAR. Seriously insane that it's free.

This is a quite useful and extremely interesting piece of software. I wish we had more control over the design of the world map, though. It would also be nice to have a display showing the time period of possible eras. Perhaps it would also make sense to be able to upload height maps that you have created yourself into the software and then modify them using the sliders. The function that allows you to drag and rotate the map to the desired position is useful and effective; however, I would like the program to save the map in the desired position instead of automatically re-centering it. I would also appreciate having more control over the sliders. Ultimately, this is the best software for generating believable world maps. I have never used a program that delivers such accurate results. I am absolutely thrilled. Thanks!

genuinely the best map/world generator available anywhere. I would've bought this if this wasn't free.

Absolute best tectonics generator, PERIOD. Runs on a laptop very well. If you're an artist, writer, creative, or anyone at all who needs a good-quality and scientifically accurate world map, this is the one to try.

It's great for free! Should be even better when the tectonics update goes live.
EDIT: Is even better!

This planetary simulator is just freaking *cool*! It simulates plate tectonics, meteor craters, differences created by planetary tilt, rainfall, and more. So you can generate dozens of physically consistent world maps in seconds. It allows you to export the maps of different properties (biome, rainfall, altitude, temperature, etc) as png files, so you can postprocess or use them in any way you like. I am so happy with the functionality.

just keep updating it. we meed lables on things to really know what the heck we are looking at
