OpenTakeoff
Free, open-source PDF takeoff for construction and flooring estimating
OpenTakeoff is a free, Apache-2.0 quantity takeoff tool for construction estimating.
Open a plan set (PDF, image or .zip), set the drawing scale, and measure - area, linear, count and deduct - with one-click room detection that traces a room when you click inside it. Apply waste percentages and supporting materials, then export quantities (SF, SY, LF, EA) as CSV or JSON.
It runs entirely in your browser: no account, no upload, no server. Plans never leave your machine.
