Certoflow Minecraft Sphere Generator review
A free browser tool for generating coordinate lists for small filled spheres.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Certoflow Minecraft Sphere Generator creates filled Minecraft spheres from a radius you select, then outputs relative x, y, z block coordinates, one triplet per line. It is aimed at solo builders and small teams who need a coordinate list for a compact shape rather than a general-purpose shape editor. The browser tool is free, requires no sign-up, and does not access a Minecraft world. You can translate the coordinates to a build center for Java or Bedrock; block placement still happens separately in-game.
The workflow stays focused on one shape: a sphere. Choose a radius from 1 to 30 blocks, generate the filled voxel sphere, then copy the plain-text coordinate list to the clipboard for build notes or scripts. The published maximum dimension is 61 blocks, corresponding to the stated radius limit. That scope suits small coordinate-based builds, but builders who need other shapes or a broader modeling workflow should look elsewhere.
Its local browser processing is a practical fit when keeping settings and generated output off the vendor’s servers matters. The page can also be used offline after it has loaded, which helps when an internet connection is unavailable later. In return, the output is coordinates rather than an in-game build action: the tool does not place blocks for you. Choose it for a free, narrow utility to plan small filled spheres; choose another approach if you need a shape library or direct placement in a Minecraft world.
