Block Round vs Block Shape Generator

Block Round is a free browser tool for making circles, ellipses, spheres, and ellipsoids with Minecraft block textures. Its 2D modes offer Euclidean, Bresenham, and Threshold algorithms; the 3D modes include X, Y, and 45-degree diagonal cuts, with a 3D preview. Users can choose blocks such as Grass Block, Dirt, Stone, Oak, Diamond, Sand, and Gravel, or a Random mix. The tool exports 2D figures as PNG and 3D figures as Sponge schematic v2 files, which WorldEdit, Litematica, and MCEdit can import. It runs in a browser without installation, an account, or a backend, and works offline as a PWA. Settings last for the session and reset to defaults after a reload. A technical math companion is available in nine languages, with each PDF described as at least 25 pages. The project states that its code, layout, design system, and sound engine are All Rights Reserved, and says it is not affiliated with, endorsed by, or sponsored by Mojang Studios or Microsoft.

Block Shape Generator is a free web tool made for builders to create block-based shapes. Users can select a sphere, cone, dome, or cylinder, then set a radius or diameter, height, and color. A hollow-shape control creates a shell. The preview includes zoom controls and a grid-lines toggle, and the interface displays the number of blocks required. Users can inspect the current layer or view the top layer in 2D before using Generate Shape to create the selected form. The page recommends Google Chrome or Opera and reports that Edge is not compatible. It also displays controls labelled Unlock features and Enable Model Movement, each marked with a test-tube symbol, but gives no explanation of their terms. The maker invites users to suggest ideas through its official Discord server and links to a donation page for development support. The listed free plan states no numeric limits. The page does not state security, privacy, or compliance practices, so readers looking for those details will not find them here.
