Astroworld Circle & Dome Generator vs Mcgic 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.

Mcgic Circle Generator creates Minecraft circles, ellipses and sphere slices, with real-time 2D and 3D previews. It runs in a browser and supports shapes from 1 to 512 blocks wide, with block counts, coordinates and a layer-by-layer guide. Builder Mode can guide block placement step by step or let users mark blocks directly on the canvas. Designs can be exported as PNG, SVG, JSON with world coordinates, or a .schem file compatible with WorldEdit and MCEdit. The tool has Dark, Light, Forest, Ocean and Classic themes, and saves settings in the browser to restore the last session without an account. On phones, Controls, Preview and Export tabs accompany pinch-to-zoom and touch panning. Mcgic says projects and exports remain on the user’s device rather than being uploaded automatically, though it may use minimal anonymous analytics and third-party integrations. The generator works with full blocks only; slab and stair circle generation is planned for a future update. It is free, requires no login and is available on the web, Android and iOS.
