Robot Build Lab

Draft robot configs across the six verified part slots, save them in this browser and compare side by side. The Lab deliberately computes no DPS, damage or best-build rankings — no verified stat data exists in any public source, and this site does not invent values.

This is a drafting tool. It stores your part choices in this browser only and compares saved drafts side by side. It does not compute stats — no verified stat data exists, so none is shown.
