BlockBlend vs Pixel Circle Generator

BlockBlend is a free browser tool for making Minecraft block palettes and geometric build blueprints. Its Circle Generator creates circles, rings, spheres, domes, and cylinders, with block counts, bounding-box information, and layer-by-layer views. Outputs include WorldEdit commands, ASCII blueprints, and JSON. The CraftLab palette library contains more than 300 blocks and can generate combinations around moods such as Medieval, Cyberpunk, Fantasy, and Oceanic. Palettes can be previewed in 3D, shared with the community, and exported as weighted WorldEdit //set commands. The Free plan is listed at free and includes unlimited palettes, all blocks, WorldEdit export, and community sharing. Image-to-palette conversion, schematic import, and map art are marked as coming soon.

Pixel Circle Generator is a free web tool for making Minecraft circles, ellipses, arcs, and spheres. Shapes can be outlined or filled, with configurable outline thickness. Dimensions use radius or diameter controls; ellipses add an Ry setting, and arcs accept start and end angles. Sphere previews show one layer at a time from −R through +R, with an option to copy commands for every layer. Generated designs can be downloaded as PNG or SVG, copied as grid text, or converted to /setblock commands for one layer or all sphere layers. Preview controls adjust pixel size, block color, grid, and axes. The tool provides coordinate output and layer-by-layer viewing, but no 3D preview. It runs in a browser and has a free plan priced at free. The site states that it is not affiliated with Mojang or Microsoft.
