Block Shape Generator vs SeedLander

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.

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.
