General guidance from repository metadata, not legal advice. How we score
From the README
Professional BOQ, CAD and BIM takeoff, 4D scheduling, 5D cost model, and tendering - all in one self-hosted platform.
Like WordPress for construction companies - pick modules from the marketplace, drop in your own, or replace ours with custom-built ones. Same plug-and-play model, but for BOQ, scheduling, cost control, BIM, and tendering.
