DropLab — Weighted Loot Table Designer & Simulator

Design drop tables with fewer balance surprises

DropLab turns raw item weights into readable chances, expected economy value, and fast Monte Carlo results before you wire the table into a game.

WHAT IT DOES

• Edit item weights, quantity ranges, and per-unit values

• See live normalized probabilities and expected value per roll

• Simulate from 100 to 100,000 drops in-browser

• Export JSON, Godot data, and a Unity C# reference

INCLUDED

• Ready-to-run single-file browser app with an original example table

• Readable HTML, CSS, and JavaScript source

• Quick-start README and commercial-output license

Useful for RPG drops, roguelite rewards, chest tables, crafting materials, and prototype economy checks. Final balance should always be tested in the context of the complete game.
