Sandustry Upgrade Planner
Choose what you want to improve, enter how much Fluxite you have, and build an upgrade plan around your current tools, weapons and drones.
What are you trying to improve?
Upgrade type
Fluxite upgrades improve tools, weapons and drones. Artifact Augments are a separate progression system. They do not share a currency.
Current upgrades
Not set yet. Unknown progress is not treated as level 0.
Recommended next
Choose a goal to get a plan. The best upgrade depends on what you're doing next.
Your upgrade plan
Current upgrades are not set. The plan assumes no purchases yet, which is not the same as confirmed level 0.
Add recommended upgrades, or optimize the current Fluxite budget.
Need more Fluxite?
Your plan needs 0. You have 0. The current budget covers this plan.
Plan Fluxite productionOptimize uses the selected goal weights, current levels and confirmed Fluxite costs. It is not a random or fixed demo list.
The best upgrade depends on what you're doing next.

See relevant Artifact puzzlesFluxite is spent on tool, weapon and drone upgrades. Each path has its own confirmed levels and costs. A maxed path is not recommended again.
Artifact Augments unlock through Artifact progression and pending choices. They are not bought with the same Fluxite budget as shovel, gun or drone upgrades.
If a save records current levels, use that state before optimizing. If it does not, leave current upgrades unset rather than pretending they are level 0.
The best upgrade depends on what you're doing next. Mining should prioritize excavation. Exploration should prioritize movement and scanner utility. Combat should prioritize weapons. Automation should prioritize drones and handling.
No. Fluxite upgrades improve tools, weapons and drones. Artifact Augments are a separate progression and choice system unlocked through Artifacts.
Yes. Analyze a save first, then use that recorded Fluxite and upgrade state here. Manual edits are never overwritten silently.
The planner shows how short the plan is and can send you to the Fluxite production planner for the remaining amount.
Those paths are known from current save data, but this site only publishes a purchase cost when that cost is confirmed. They can be browsed, not bought in the plan.
