Astroworld Circle & Dome Generator vs MC Circle

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.

MC Circle is a web planner for Minecraft players who need block-by-block layouts for circular and curved builds. It generates charts for circles, ovals, half circles, and domes, with outline or filled views and optional grid lines. Numbered rows and columns guide block placement, while block counts and stack estimates support material planning. The main generator accepts sizes from 3 to 128 blocks and states support for Java and Bedrock editions. Plans can be downloaded as PNG files, copied as charts, or shared through links. The site also provides sphere plans with hollow or solid modes, layer counts, and per-layer block plans. Its coordinate output and layer-by-layer view help translate designs into builds. MC Circle runs in a browser without login, registration, payment, or subscriptions. The free plan is listed at free.
