Minecraft Shape Generator vs SeedLander

Minecraft Shape Generator is a free web tool for turning geometric forms into block-by-block Minecraft building plans. It provides layer-by-layer blueprints, a 3D preview, coordinate output, and PNG export. Shape choices include spheres, domes, circles, ellipsoids, eggs, toruses, hearts, stars, cubes, pyramids, arches, mazes, spiral stairs, towers, roofs, and more. The Hollow mode makes a shell, while Solid fills the shape. The tool shows the total number of blocks and the count for the layer currently displayed. Its visual blueprints are intended for Java, Bedrock, and console builds; the output is a plan rather than a command or mod. The layer view can be kept on a mobile device as a reference while building on a PC or console. The site identifies survival players, creative builders, and server teams as users. For symmetry, its guidance recommends odd diameters, which result in one center block. No account is required, and creations are not stored.

SeedLander is a browser-based toolkit for analysing Minecraft seeds in Java Edition and Bedrock Edition, including Java Large Biomes. Its tools cover biome maps, structure searches, ore predictions, slime chunk calculations, portal management, and team collaboration. The structure finder covers 25+ types and provides coordinates for places such as villages, strongholds, temples, mansions, and monuments. SeedLander states that most structure results on Java and Bedrock are 97%+ accurate, while cautioning that they are predictions rather than guarantees. The tools run in the browser using WebAssembly, and seeds are not sent to SeedLander servers for processing. Map, finder, and account pages support touch use on phones and tablets; a dedicated mobile app is on the roadmap. The free Basic plan includes all seed tools, 10 custom markers, and three saved portal pairs. Premium costs £1.99 per month per world and adds unlimited markers and portals, ore tracking, structure completion tracking, notes, and an activity log. A Team add-on costs £2.99 per month per world on top of Premium.
