Spec score 8.6 #11 of 25 in Construction Takeoff Software

What it is

OpenTakeoff measures quantities from building plans through a browser canvas for people and an MCP server for AI agents. Its browser app opens PDF, PNG, JPEG and ZIP plan files, processing them locally without an account or plan upload. Measurements include square feet, square yards, linear feet and each, with waste-adjusted order quantities, supporting-material lists and roll-goods cuts. Exports include CSV, Excel, JSON, PDF and DXF. Drawing OCR is supported. The MCP server runs through `npx -y opentakeoff-mcp` and works with Claude Code, Claude Desktop, Cursor and other stdio MCP clients; agent measurements need a person’s approval in the browser canvas. The default workspace keeps plans, measurements, annotations, materials and project settings in browser storage on the device. Optional connections include Google Drive, Microsoft 365, configured AI providers and a scanned-schedule service that can send a selected image to Google Gemini. OpenTakeoff is free, with no account required, and Apache-2.0 licensed. It runs on web, Linux, macOS and Windows, with an API and self-hosting options. One-Click Area is temporarily gated, and the default MCP build does not register room-detection verbs.
