Astroworld Circle & Dome Generator vs MC Circle 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.

MC Circle Generator is a free web tool for planning circle and oval block layouts in Minecraft. Choose Hollow, Filled or Border+ mode and dimensions; the grid preview updates as dimensions, modes and display options change. A row guide and pattern panel show block placements from the top of the shape to its center, while the Build Materials panel totals blocks and stacks of 64 and 16. The preview can show X/Y coordinates, and coordinate labels can also be included in exports. Blueprints download as PNG or SVG, with options for grid lines, guides, coordinates, a center marker, title, scale and background. The maker says exported layouts work with Minecraft Java and Bedrock editions, and describes the tool as responsive on PC, tablet and mobile. Ready-made reference sizes run from diameter 3 to 65. The page notes that larger pixelated circles appear rounder, while small ones can show staircase artifacts. It is intended for builders planning features such as chimney caps, arena floors, towers and mega-build foundations. The page states that the tool is not affiliated with Mojang or Microsoft.
