## What is Rust Base Builder?

Plan your Rust base before you farm a single stone.

Rust Base Builder is a 3D base planner. Put down foundations, walls, doorways, floors, roofs, stairs, doors and deployables on a grid that follows the game's own building rules, then see straight away what the base costs and what it takes to raid.

BUILD IN 3D
• Every building piece in every grade: twig, wood, stone, sheet metal and armored.
• The game's building rules: what can stand where, and stability.
• Doors, hatches, windows, embrasures and deployables, each facing the way you set it.
• Turn, copy, move and upgrade a whole group of pieces at once.

KNOW THE COST
• The full build cost in wood, stone, metal fragments and high quality metal.
• Upkeep per day, building by building.

RAID IT FIRST
• The raid cost of every piece: rockets, C4, satchels and explosive ammo.
• The cheapest way into your loot room, drawn on the base, so you can fix it before a raid group finds it.

YOURS, ON YOUR PHONE
• No account and no sign-in. Your bases are saved on your phone and work with no signal.
• Share a base with a link, or save it as a file and open it on another device.
• Opens and saves CopyPaste files.
• No ads.

Made by RustBaseDesign (rustbasedesign.com), the original base design site, since March 2024, where players find and rate base designs. Find your next Rust base. Plan it. Raid-test it.

## Version history (last 3 releases)

### 1.2 — 2026-11-04

Shared base links now open in the app. When a friend sends you a Rust Base Builder link, tap it and the base opens right here, ready to look around, copy or change. Your own base is kept safe and you can bring it back with one tap.

### 1.1 — 2026-11-03

A new layout for phones:
• A row of tool buttons above your parts: Undo, Redo, Delete, Select, Grade, Rotate, Floors and Assists
• Easy Place: green shapes show every spot the part in your hand fits, and one tap builds it
• An empty base opens with the foundation ready to place
• Pictures on the part slots and part tabs, and 9 to 30 slots in Settings

Also new:
• Mirror building: what you build is copied 2, 3, 4 or 6 times around the base's middle, or across one or two mirror lines
• Walk through your base in first person
• Upkeep for your group size: tell the planner how many of you play together
• Fixes to rotating, placing and selecting pieces

### 1.0 — 2026-11-01

No release notes.
