What is a Minecraft schematic planner?

Building from a schematic in survival is a slow, layer-by-layer process: place a row, count the next one, glance at the plan, repeat. A schematic planner is a viewer optimized for that workflow: one designed to sit next to you while you build, rather than for showing off finished work.

Shulkr's slicer mode steps through any schematic one layer at a time along the X, Y, or Z axis. Each layer is a clean top-down (or side) cross-section, easy to mirror block-for-block as you place in game. Switch axis to plan vertical walls or floors. Keyboard shortcuts step through layers without the mouse.

On your phone, next to your game

The viewer is fully responsive and runs on any modern phone or tablet with WebGL. Open your .litematic or .schem on your phone, prop it next to your keyboard, and you don't need to alt-tab out of the game to check the next row.

Measure before you mine

The area-measure tool reports width, depth, and a full material breakdown for any rectangular selection, handy for estimating resources before you break ground. Hold Ctrl in slicer mode and drag across the layer to mark the region, and the sidebar instantly shows the count of every block type inside.

Shulkr is fully client-side. Your schematic file never leaves your device: parsing and rendering happen entirely in your browser.

FAQ

Frequently asked questions

How do I plan a Minecraft build from a schematic?

Open the schematic in the Shulkr viewer, switch to slicer mode, and step through one layer at a time along the X, Y, or Z axis. Each layer shows you exactly where every block goes. Mirror it block for block as you place in survival. Use the area-measure tool to count blocks of a given type for any region.

Can I see how many blocks I'll need to gather?

Yes. In slicer mode, hold Ctrl and drag across the layer to mark a rectangular region. The sidebar instantly shows the region's width and depth in blocks plus a full material breakdown: every block type and quantity in the selection. Useful for estimating resources before you start mining.

How does the slicer view work?

Slicer shows a single cross-section of the schematic at a time, with controls to step layer-by-layer along any axis (X, Y, or Z). It's the same kind of view Litematica's print mode uses, perfect for following a plan in survival without alt-tabbing. Keyboard shortcuts let you advance layers without leaving the build position.

Can I use this on my phone next to my game?

Yes. The viewer is fully responsive and works on modern phones and tablets with WebGL support. Open the schematic on your phone, prop it next to your keyboard, and step through it one-handed while you place blocks in survival. No need to keep a laptop nearby or alt-tab out of Minecraft.

Can I inspect individual blocks while planning?

Yes. Click any block to see its id, world coordinates, and full blockstate properties in the sidebar, useful for getting stair orientations, log axes, redstone components, or waterlogged variants exactly right.

Are my files uploaded to a server?

No. Everything runs entirely in your browser using WebGL and JavaScript. Your schematic files never leave your device.

Does this work on mobile?

Yes. The viewer is fully responsive and works on modern phones and tablets with WebGL support, which is handy for keeping a plan open next to you while you build in survival. Large or complex schematics still render best on desktop, where performance and precise mouse controls make exploration smoother.
