What it is

Astroworld Circle & Dome Generator is a free web tool for planning Minecraft structures with pixel grids. It generates circle outlines, filled circles, domes and sphere shells from whole-block diameters between 1 and 256. The selected shape’s total block count appears before construction. Gold cells indicate blocks to place, while dark cells indicate empty space; large grids are compressed to fit the screen. A layer slider lets you inspect dome and sphere-shell builds one layer at a time. The page says block positions are calculated in your browser from the diameter entered. You can embed the generator in a website or server wiki with an iframe and set its width, height and theme. The free plan costs nothing, with no sign-up and no ads. It is intended for Minecraft builders planning towers, arenas, greenhouses, planetariums and spheres.
