MinecraftCircle Tools vs SchemForge Sphere Generator

MinecraftCircle Tools is a free web collection for planning Minecraft block geometry. Its circle and oval generator creates symmetrical outline or filled plans with coordinates, layer views, and exports to PNG, Litematic, CSV, TXT, or Markdown; plans can also be shared by URL. Other generators produce hollow or filled spheres, upper-half dome roof plans, and symmetric five-point stars. Sphere views show horizontal slices and layer counts. The sphere and dome interfaces display dimensions up to 129, while the underlying engine and exports support dimensions through 256. Pixel-art images are resized and color-quantized in the browser rather than sent to the server. Circle build progress is kept in browser local storage and, according to the site, is not sent to its server. The site says its grid and row plans describe block positions usable in Java and Bedrock Edition, while Litematic supports compatible Java mod workflows. No account is required. The maker describes the project as independent and not approved by or associated with Mojang or Microsoft. ToolSphere Tech LLC operates the website, whose legal notice provides the tools as-is and as-available.

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.
