Use the official Demo link for Steam App 3490390 or the developer's itch.io page, and keep Demo-era advice separate from the paid Early Access game.
The official Sandustry Demo is separate from the paid Early Access game. The Steam Demo uses App ID 3490390, while the paid game uses App ID 2764460. The developer also maintains a Sandustry page on itch.io.
Where to get the official Demo
Use an official link rather than an unofficial download mirror. The Steam Demo's live download state and supported platforms can change, so confirm the current button and requirements on the store page.
What the Demo is designed to show
The developer's itch.io description presents the Demo around the game's core systems: falling-sand physics, mining, base building, automation, exploration, puzzles, bosses, and technology upgrades.
That makes it useful for testing the basic “every pixel is a resource” idea before purchasing. It does not make every old Demo value, item, or progression limit valid for the current paid game.
Demo versus the paid game
| Detail | Demo | Paid Early Access game | | --- | --- | --- | | Steam App ID | 3490390 | 2764460 | | Purpose | Free sample of the core systems | Current developing game | | Version scope | May preserve older mechanics or limits | Updated Early Access build | | Store status | Must be checked live | Released into Early Access Aug 13, 2026 |
The current official homepage lists both Steam products. This is the clearest way to avoid opening the wrong product page.
Why old Demo guides need caution
Most itch.io development logs and the collected long-form Demo playthrough come from 2024–2025, before the paid Early Access launch. A Steam Community Demo review from June 2026 is newer, but it still reflects one player's experience with the Demo rather than an official list of current main-game issues.
Use old Demo material to understand the concept, not to establish current prices, research costs, content limits, mod folders, or paid-game bugs. The Sandustry mods guide explains why the old Demo loader method should not be reused.
Before downloading
- Confirm that you are on App ID 3490390 for the Demo.
- Check the live supported-platform and download information.
- Treat Demo progress and compatibility as separate from the paid game unless the store explicitly says otherwise.
- Recheck current differences after major Early Access updates.
