Astroworld Circle & Dome Generator vs Block Shape Generator

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.

Block Shape Generator is a free web tool made for builders to create block-based shapes. Users can select a sphere, cone, dome, or cylinder, then set a radius or diameter, height, and color. A hollow-shape control creates a shell. The preview includes zoom controls and a grid-lines toggle, and the interface displays the number of blocks required. Users can inspect the current layer or view the top layer in 2D before using Generate Shape to create the selected form. The page recommends Google Chrome or Opera and reports that Edge is not compatible. It also displays controls labelled Unlock features and Enable Model Movement, each marked with a test-tube symbol, but gives no explanation of their terms. The maker invites users to suggest ideas through its official Discord server and links to a donation page for development support. The listed free plan states no numeric limits. The page does not state security, privacy, or compliance practices, so readers looking for those details will not find them here.
