Stillroom HQ · Soap Making Studio
Intelligent soap formulation
for modern makers.
Create recipes, calculate lye and water automatically, monitor soap properties, track inventory, scale production batches, and generate INCI labels — inside one calm, connected workspace.
More than a soap calculator.
Stillroom HQ was designed to support the full workflow of modern soap makers — from formulation and production to inventory, costing, workshops, and batch tracking.
Rather than jumping between spreadsheets, calculators, notebooks, labels, and disconnected apps, everything stays connected inside one calm workspace.
The Soap Making Studio — lye calculator, property bars, and batch scaling in one view.
