Mega-builds in days, not weeks.

CobbleStudio is voxel CAD for Minecraft. Place by the thousand. Select with Photoshop modifiers. Extrude faces, cut windows, group walls and recolor a whole wing in one click. Undo absolutely everything. Built for the work Hermitcraft hermits ship in 5 weeks — done in a weekend.

Why this is different

Not WorldEdit. Not Litematica. Parametric.

You already use the tools that get you 80% of the way there. CobbleStudio is what they should have been — designed around selection and undo, not commands and re-authoring.

WorldEdit

Type commands.

Paste, set, copy, undo. Powerful, but every change re-runs the chain. Move a wall, you re-issue every command that touched it.

Litematica

Stitch schematics.

Author the build elsewhere. Place from a hologram. Beautiful at placement; static once authored. Edit means re-author.

CobbleStudio

Place. Select. Group. Undo.

Direct voxel editing with Photoshop-style selection, Cinema 4D–style group hierarchy, and snapshotted undo that covers every action you take. Group a wing, recolor it in one click. Change your mind, hit Cmd+Z.

Small cohort, rolling reviews. We're picking ~30 builders who build at scale, have opinions about UX, and tell us when something's wrong. If that's you, the answer's usually within a few days.
