Sandustry Mods: Workshop, Fluxloader and Compatibility
Find Sandustry mods through Steam Workshop and Fluxloader, compare map, QoL, recipe, and co-op entries, and check dependencies before installing.
For Sandustry mods, start with the official Steam Workshop listing and the community Fluxloader catalogue. Check each mod’s version, tag, dependencies, and save-risk notes before installing; do not assume an unofficial tweak is an official feature.
Where the collected sources point
The Steam Workshop page is presented as the official place for Sandustry mods and maps. The collected Fluxloader index is a separate community catalogue with versioned entries and tags such as map, qol, visual, elements, recipe, loader, lib, and multiplayer.
Fluxloader’s list includes examples such as Custom Map Loader, Core Lib, Better Save Menu, Bigger Grabber, Flow Control, Creative Mode, and Sandustry Together. These names show the range of community projects; they are not a recommendation that every entry is current or compatible with every build.
Check compatibility before installing
Use this checklist for each entry:
| Check | What to verify |
|---|---|
| Version | The catalogue version matches the game and loader build you run. |
| Dependencies | Required libraries, such as Core Lib, are installed at a compatible version. |
| Category | Map, QoL, recipe, visual, loader, and co-op mods change different parts of a save. |
| Readme status | Experimental projects may report desyncs, crashes, or incomplete synchronization. |
| Save safety | Back up an important factory before testing a modded session. |
The Fluxloader readme for Sandustry Together explicitly labels it experimental and warns about bugs, desyncs, crashes, and possible save corruption. That warning is a useful baseline for other early-access projects too, but it should not be generalized into a claim that every mod is unsafe.
Avoid unsupported claims
One collected article describes memory-injection cheats and says traditional mod managers are unavailable. Those claims conflict with the collected Steam Workshop listing and the Fluxloader catalogue, so they are not used as installation instructions here. The reliable conclusion is narrower: Sandustry has an official Workshop channel plus an active community loader ecosystem, and individual projects must be checked on their own documentation.
A low-risk testing routine
Create a separate test save, install one mod or one dependency group, launch the game, and verify that the intended map, building, recipe, or quality-of-life change appears. Only then connect it to a long-running factory. When a game update lands, re-check the mod’s release notes and dependency versions before reopening the save.
