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
01
Best for Drone automation
100 Fluxite
You're planning around Drone automation. Drone Fleet improves drone fleet size and transport cycle time, so the next level has more immediate value for this goal than investing the same Fluxite elsewhere.
02
Best for Drone automation
200 Fluxite
You're planning around Drone automation. Quantum Propulsion improves drone fleet size and transport cycle time, so the next level has more immediate value for this goal than investing the same Fluxite elsewhere.
03
Best for Drone automation
500 Fluxite
You're planning around Drone automation. Drone Fleet improves drone fleet size and transport cycle time, so the next level has more immediate value for this goal than investing the same Fluxite elsewhere.
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.

vs
Digging Speed I
Increases shovel digging speed by 15% per level.
100 Fluxite
Broader Shovel
Larger excavation footprint for the same swing.
400 Fluxite
Current goal Drone automation
For Drone automation, these two purchases are close enough that cost and current level matter more than a single winner.
Artifact Augments are not Fluxite purchases. This planner only uses recorded save fields and will not invent the options currently on screen in-game.

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.
