Astroworld Circle & Dome Generator vs MinecraftCircle Tools

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.

MinecraftCircle Tools is a free web collection for planning Minecraft block geometry. Its circle and oval generator creates symmetrical outline or filled plans with coordinates, layer views, and exports to PNG, Litematic, CSV, TXT, or Markdown; plans can also be shared by URL. Other generators produce hollow or filled spheres, upper-half dome roof plans, and symmetric five-point stars. Sphere views show horizontal slices and layer counts. The sphere and dome interfaces display dimensions up to 129, while the underlying engine and exports support dimensions through 256. Pixel-art images are resized and color-quantized in the browser rather than sent to the server. Circle build progress is kept in browser local storage and, according to the site, is not sent to its server. The site says its grid and row plans describe block positions usable in Java and Bedrock Edition, while Litematic supports compatible Java mod workflows. No account is required. The maker describes the project as independent and not approved by or associated with Mojang or Microsoft. ToolSphere Tech LLC operates the website, whose legal notice provides the tools as-is and as-available.
