CartoVoxel Minecraft Shape Maker vs MapMC Worlds

CartoVoxel Minecraft Shape Maker is a free web tool for planning block geometry with a live 3D preview and coordinate exports. It provides 11 shapes: sphere, cylinder, cone, pyramid, dome, prism, torus, ogive cone, hyperboloid, star and spiral. Users can adjust dimensions, select a material color preset or Minecraft block ID, and toggle filled geometry. A layer view displays generated coordinates in a grid one Y level at a time. Export options are a browser-readable layer guide, JSON coordinates and shape settings, and a Java mcfunction intended for Minecraft Java Edition creative worlds or datapack workflows. Shape generation, previews and downloads run locally in the browser after the page loads; the page says shapes and settings are not uploaded. The tool does not create Litematic, schem, Bedrock structure, mcworld or complete world files. CartoVoxel describes the service as web-based, with no downloads or heavy software required. The listed plan is free and includes all 11 shapes, live 3D and layer views, and the stated exports.

MapMC Worlds converts a selected real-world map area into a downloadable Minecraft world. It uses OpenStreetMap data and the Arnis conversion engine to generate features such as roads, buildings, water, land cover, and terrain. The browser-based generator needs no local installation, and the site says it works on phones and tablets. Worlds can be downloaded as a Java world ZIP or a Bedrock.mcworld file. Standard detail supports areas up to 40 km² for Java and 32 km² for Bedrock; high detail is limited to 5 km². Free use includes one map generation or 300 signup Credits, plus one AI texture generation; Seed Map and all Finders are always free. There is no subscription: users can make one-time generation payments or top up Credits, which never expire. Plus costs $19.90, paid once, Pro costs $49, paid once, and Studio costs $99, paid once. Generated world files are automatically deleted after 30 days, so users need to download files they want to keep.
