Sandustry mods
Sandustry mods are first-party supported. Steam lists Steam Workshop among the store categories. The official about text says the game was built with modding in mind: visual tweaks, hand-crafted maps, and entirely new buildings and processes. Community installers such as Fluxloader exist next to that official door. Official store copy, the Hooded Horse wiki roster, and Steam patch notes are the only sources for numbers on this page. Community names stay in the alias column.
Use Workshop first
If a mod is on Steam Workshop for app 2764460, subscribe there. That is the official distribution path and the one that survives a reinstall. Dedicated modding tools are promised in the store copy. This wiki will not host third-party binaries.
Custom maps are a documented mod class. They are not a second campaign you should expect to rank on. Play them as sandboxes after you understand Wet Sand, or as stress tests for belts.
Fluxloader and friends
Community pages describe Fluxloader as an installer for deeper code mods. That is community infrastructure, not a Hooded Horse product. If you use it, keep a vanilla save. Early Access is on hotfix pace. v0.5.3 already shipped logging and memory work. A loader that pinned an older demo build will lie to you.
Never paste a random 'industry mod' executable from an SEO farm. sandustrywiki.online lists several of those pages. They are not sources.
Save hygiene
Workshop items can add buildings the official wiki does not list. Label those saves. A support dump from a modded factory will waste Lantto’s hotfix time and yours. Export a vanilla copy before you subscribe to a process overhaul. Steam Cloud is on the store page; it is not a reason to skip local backups while EA is this young.
More detail worth keeping
A good Sandustry mod looks like a missing official building, not like a different genre. New process, new map, quieter pixels. If a Workshop thumbnail promises infinite Gold, it is fighting the design Hooded Horse bought. Use it as a sandbox and keep it off your main save. Fluxloader is a community door for things Workshop cannot hold. Treat it like source-only. If you cannot read what it injects, do not inject it. EA hotfixes will break loaders. That is normal, not a betrayal.
Practice that survives a patch
When a Workshop item adds a building, give it a local name in your head that includes the mod title. Do not file it onto our official roster. Our materials and buildings tables are the Hooded Horse floor, not a union of every subscriber list. If we cannot cite a first-party page, it does not get a slug.
Close the loop
Prefer visual mods and maps until the official API page on the Hooded Horse wiki is more than a stub. Process overhauls are how you lose the ability to read our research table.
If a mod requires Fluxloader and a Discord zip, wait a week. EA is young. Workshop will grow. Patience is a better loader than a random archive.
Frequently asked questions
Does Sandustry officially allow mods?
Yes. Steam Workshop is on the store page and the about text invites new buildings and processes.
Are demo mods compatible with Early Access?
Do not assume it. EA launched 13 August 2026 after a year of demo hotfixes. Prefer Workshop items updated after that date.
