BlockBlend vs SchemForge Sphere 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.

SchemForge Sphere Generator is a browser tool for building Minecraft spheres with custom width, height, and depth, up to 256 blocks. It shows exact Y layers in a top-down guide that marks placed blocks and the previous layer, alongside a rotatable 3D preview. Users can choose a filled sphere or a hollow outline; wall thickness applies only to outline mode. The 3D preview becomes simplified above 31 blocks. Exports include a PNG blueprint, a copied or downloaded layer, and Java Edition or WorldEdit commands. The tool guide suggests WorldEdit for a full sphere and Java Edition commands for layers that are manageable to build. Generation and exports run locally in the browser without an account, AI token, or credit. The Free plan costs nothing and includes one build every day. A 48-hour option costs 0.99 USD one time; Creator costs $3.99 a month, billed yearly at 47.88 USD, with fair-use safeguards. Java Edition exports may require in-game editing for some mod or server configurations.
