Choose a tool
Each utility is intentionally small: it should answer one practical Sandustry planning question clearly.
Production Ratio Planner
Scale multiple verified input/output rows, save them locally and copy the table.
Factory Checklist
Track early Water, Wet Sand, Gold, Residue, Transport and Expansion checks.
Troubleshooting Helper
Pick a symptom and jump directly to the right fix path.
Lights Tool
Use a lightweight static utility kept separate from long-form guides.
Use tools after observation
The tools do not replace in-game checks. They help preserve the numbers and decisions you already verified.
Make one stage physically stable
If Water, output space or byproducts are failing, use troubleshooting before scaling a ratio.
Check slow productionRun the checklist
Tick off the early factory checks so a bigger build does not copy a hidden flaw.
Open checklistRoute by symptom
Use the helper when the factory is visibly failing but the right diagnostic page is not obvious.
