MC Planner
ModSee your plan inside Minecraft

Plan your world before you build it.

The MC Planner app opens your Java world in 3D with your own textures. Draw paths, areas and buildings on the real terrain, count every block, plan it live with your friends, and see the plan in the game with the MC Planner mod.

MC Planner is a desktop app for Windows, macOS and Linux. It needs Minecraft: Java Edition.

MC Planner · Demo world
A village planned on a real Minecraft world in MC Planner: a road, a market square, houses and fields drawn on the terrain, with the plan list on the left.

Works with

  • Windows, macOS and Linux
  • Java Edition 26.2
  • Worlds from 1.18 to 26.3
  • Modded worlds and dimensions
  • Resource packs and mod textures
  • In the game: Fabric mod for 26.2
  • Bedrock: not supported

How it works

Install it. Plan it. Build it.

The desktop app finds your worlds and game files by itself and opens them in place, straight from your saves folder. No zipping, no dragging around.

Features

Everything you need to plan the big one.

Every screen on this page is MC Planner itself, on a world we made, with the game's own textures.

Paths, areas & buildings

Know every block before you mine one.

Draw on the real terrain and pick the block it's made of. You see it in that texture, and the inspector counts every block, with stacks.

1,294blocks of dirt path
20stacks + 14to gather for the main road

Pinboard

Pin the idea to the place.

Notes, checklists, pictures and links, right on the building they belong to. No more screenshots lost in the group chat.

  • A board on every path, area and building
  • Everyone sees changes live

Schematics

Try the build in place. Get the shopping list.

Import .litematic, .schem, .schematic or .nbt files and place them with real blocks. The inspector lists every material. Files stay in your browser and are never uploaded.

FAQ

Questions, answered plainly.

Is MC Planner free?

Planning alone is free, with every feature and no account. Planning together needs a plan for the host: Cloud, Team or Lifetime. Friends join free.

Which systems does MC Planner run on?

MC Planner is a desktop app for Windows, macOS and Linux, on the download page. It finds your worlds and game files by itself, opens worlds straight from your saves folder and keeps itself up to date. The same planner also runs in a desktop browser.

Which Minecraft versions does it support?

Minecraft: Java Edition. It's built for 26.2 and reads worlds from 1.18 to 26.3, including modded worlds and modded dimensions. Bedrock Edition isn't supported.

Is the mod free?

Yes, for everybody, with every feature. The mod never checks whether you have an MC Planner plan. Plan files (.mcplan) open without an account; for a shared world you need a free Lab43 account and an invite from its owner. MC Planner's paid plans pay for hosting shared worlds, which is part of the app.

Which versions does the mod run on?

Minecraft: Java Edition 26.2, with Fabric Loader and Fabric API. Older versions are coming. There's no version for Forge, NeoForge or Bedrock.

Do I need Minecraft installed?

You need to own Minecraft: Java Edition, but it doesn't have to be installed on the computer you plan on. MC Planner gets the block textures for you straight from Mojang (only the block files of your world's version, once), or reads them from your own game file. Nothing from Mojang is bundled with MC Planner.

Will it change my world?

No. MC Planner only reads your world. Your plans are stored separately.

Can I use it in my browser?

Yes. The same planner runs at app.mc-planner.com in a desktop browser, with nothing to install. It's handy for a quick look or a friend's computer. The desktop app does more: it finds your worlds and game files by itself and opens worlds in place.

Does it work on my phone?

No. MC Planner is for computers: the desktop app for Windows, macOS and Linux, or a desktop browser. It uses 3D graphics, keyboard shortcuts and your game files.

Is my world uploaded?

Only if you share it. On your own, everything stays in your browser. When you share, the world files and a colour map are uploaded to our server so friends can open it with a link. Your game's textures are never uploaded.

What do my friends need?

The invite link and a free account. They join in the desktop app or a desktop browser, see your world with their own textures or in map colours, and plan with you live.

Can I use schematics?

Yes: .litematic, .schem, .schematic and .nbt. Imported files stay in your browser and are never uploaded. Friends see a box with the link to the original until they import the same file.

Is MC Planner made by Mojang or Microsoft?

No. MC Planner is an independent tool by Lab43. Not an official Minecraft product. Not approved by or associated with Mojang or Microsoft.
