Show HN: Purple Hammer – construction takeoff and estimating in Tauri/Rust/WASM

Purple Hammer – construction takeoff and estimating in Tauri/Rust/WASM operates in show hn launch.

Profile

Purple Hammer does construction takeoff. You measure quantities off PDF drawings and a built-in spreadsheet lets you read from databases, formulas, assemblies etc to price the job. This matters because most takeoff software (Bluebeam, Planswift) do not have the spreadsheet side of things built in.Stack is Tauri 2, Rust, SolidJS. The render and spreadsheet engines are both custom, compiled to WASM with modified PDFium for parsing. One codebase builds native Mac and Windows.Performance is most of the work. A 500-sheet set opens in about a second. Million+ vector drawings hold 120 FPS on mid hardware. It feels somewhat faster that any other construction viewer I’ve tested. Compare the live demo
