Rustexa tools
Deterministic Rust calculators built on one verified recipe source. No guesses, no estimates — the same numbers the game uses.
Know exactly what you need to farm. Build an explosive loadout — rockets, C4, satchels, explosive ammo — and get the full resource requirement, the crafting breakdown and the components you cannot farm. Or work backwards: enter what you already have and see what it makes.
Recipe data checked 2026-09-07 · Official Facepunch Rust wiki (wiki.facepunch.com/rust/item/…)
Type in the clones you already have and get the exact planter layouts that breed a god clone. Real gene weights, slot-by-slot maths you can check, and a straight answer when a target simply is not possible with what you own.
Runs entirely in your browser · nothing uploaded
Pick the doors and walls you need to break and Rustexa finds the cheapest sulfur way through them — rockets, C4, satchels or explosive ammo, per target. Then send the whole loadout straight to the Farm Calculator.
Independently verified raid data · unconfirmed targets left out
See what your ore turns into, how long it takes in a Furnace, Large Furnace or Electric Furnace, and exactly how to spread it across your slots so the whole smelt finishes as early as possible.
Official smelt times · wood cost left blank because nobody publishes it
Drop in whatever you looted and see exactly what comes back — from the monument recycler or the safe zone one. Guaranteed scrap and components are kept separate from the rolls you might not win.
