Short answer
The current official Steam listing labels Sandustry as an Early Access game. It says the Early Access version is fully playable and has the content and features described on the store page, while the full version is planned to grow with community feedback. The Steam page also currently displays a demo entry, but demo availability and store access should be checked directly in your region.
Early Access is the current stage label
Early Access is not the same claim as a final release. The store explains that the game may change further, and the developer statement says the team plans to use player feedback to expand and improve the game. Future additions described on the page include more content, buildings, resources, production chains, quests, biomes, and technologies, but this is a plan rather than a promise of a date.
The safe way to describe the current build is therefore “fully playable Early Access,” using the official store wording and the date of the last check. Do not convert that status into a permanent completion statement, and do not infer a fixed roadmap schedule from the existence of a release announcement.
Current access and the demo distinction
The Steam listing is the canonical place to open the current purchase and play surface. It shows a demo entry as well, but the historical developer page and older demo material should not be treated as identical to the current Early Access build. A demo may use different terminology, content, balance, or mod compatibility.
If you are following an older guide, check whether it refers to the demo or to Early Access before copying a recipe, tool name, or mod instruction. The supplied research specifically flags demo-era modloader material as version-sensitive. That is why this site links to the official store and keeps the demo guide outside the confirmed publish queue.
What this page does not freeze
Price, discounts, tax, region, supported languages, and store fields can change. The page deliberately does not show a universal price or claim that a store observation applies to every country. For platform and language questions, open the current listing in the intended locale and record the check date.
The same caution applies to multiplayer, Game Pass, mobile, and mod compatibility. None of those answers should be copied from a Steam store description that does not explicitly support them. A “not confirmed here” status is more useful than a confident but stale answer.
Safe next step
Open the official Steam listing, read the current stage label, and compare the visible store fields with the question you are trying to answer. Then use the Beginner Tips page for mechanics that are already source-backed. This keeps access guidance current while the local wiki remains useful for learning the game’s automation and exploration loop.
