Modding
Sandustry is built with modding in mind. Learn how to add visual tweaks, custom maps, new buildings and full overhauls with built-in mod tools.
Introduction
Sandustry is designed to be modified from day one. The developer has emphasized built-in modding support, so players can add visual tweaks, hand-crafted custom maps, entirely new buildings and production processes, and even complete gameplay overhauls. Because the game ships with dedicated modding tools, creating content does not require reverse-engineering the game — it is a supported, intended part of the experience. The modding category covers the full range, from the simplest palette swap to full conversions, with practical guides for installing mods, creating your own content and understanding the mod folder structure and how the built-in loader handles it.
Mod Type Overview
| Mod Type | Scope | Example |
|---|---|---|
| Visual Tweaks | Lightweight | Changed palettes and textures |
| Custom Maps | Medium | Hand-crafted world layouts |
| New Buildings | Large | Added machines and processes |
| Full Overhauls | Complete | Converted factory experience |
Modding Categories
Visual Tweaks
The lightest class of mods, changing how the world looks without altering gameplay. Reskins, palette changes and texture packs let you personalize the pixel aesthetic. Visual mods are the easiest way to learn the modding pipeline before tackling content mods, because they use the exact same folder structure and loading system.
Custom Maps
Hand-crafted maps designed by the community, replacing or supplementing the procedurally generated worlds. Custom maps can offer curated challenge layouts, beautiful showcase worlds or themed factory designs that the base generation would not produce naturally. Combining a custom map with a new-buildings mod produces a fully custom experience, and map mods are a great way to experience Sandustry from a different angle after a long playthrough.
New Buildings
The meat of Sandustry modding: adding entirely new buildings and production processes. A machine mod can introduce new inputs, outputs, recipes and automation options, extending the factory sandbox beyond the base game's tech tree. Balance new recipes carefully against existing production chains so the progression stays satisfying, and test your mod with the built-in tools before sharing it with the community.
Modding Tools
The dedicated tools shipped with the game that make all of this possible. Because modding support is built in, tools cover map creation, content definitions and testing without external editors. These tools lower the barrier enough that anyone can create content, and using them to validate a mod before sharing it keeps the community ecosystem healthy.
Core Mechanics
Modding in Sandustry works through the game's built-in tooling. Map editing lets you craft custom worlds, content definitions let you add buildings and recipes, and the folder-based mod structure keeps mods separated so they can be enabled or removed independently. Because the developer explicitly built mod support in, the modding layer is a first-class part of the game rather than a community hack. This means mods are stable, documented and safe to install, and the modding category can describe the official pipeline with confidence — where mods live, how they load and how to validate your own content with the shipped tools.
Advantages
Built-in mod support is a significant strength for a factory sandbox. It extends the game's lifespan far beyond the base content, since the community can add buildings, maps and overhauls. Custom maps give the game curated experiences beyond procedural generation, and the low barrier to entry means even casual players can participate. The modding ecosystem turns a single-player game into an ever-growing one, and because modding is officially supported, the wiki can provide authoritative installation and creation guides instead of community reverse-engineering tips that break on every update, which keeps the whole ecosystem stable and approachable. This makes modding an accessible and rewarding part of the Sandustry experience for everyone.
Challenges
Modding does have a learning curve. Understanding the mod folder structure and content definitions takes time, and poorly balanced custom buildings can break the progression feel. Mods are also community-maintained, so quality and compatibility vary — a mod written for one game version may not work after an update. Always back up your save before installing large overhaul mods, and check each mod's required game version before enabling it. During Early Access, frequent game updates mean mod compatibility can change quickly, so players should expect to wait for mod authors to catch up after each patch, and should keep their favorite mods labeled by version.

Quick Tips
Start with visual tweaks to learn the modding pipeline before building custom machines — the folder structure and loading behavior are identical, so the skills carry over directly. A simple reskin teaches you everything you need to know about how mods are packaged. You will have a working first mod and the confidence to try a bigger project next.
Keep mods separate and labeled by version so you can disable them after game updates; a mod built for one version may silently break in the next. Clean labeling makes it easy to remove a broken mod without touching the rest of your setup. It is a small habit that saves a lot of troubleshooting later.
Back up your save before installing full overhaul mods — they change core mechanics, and rolling back a broken save is far harder than restoring a backup. A quick save copy takes seconds and removes the biggest risk of heavy modding. A minute of precaution keeps hours of progress safe.
