Our verdict on OpenTakeoff

OpenTakeoff is an open-source construction and flooring takeoff engine for estimators, developers, and teams that want local plan measurement. It runs in a browser and accepts PDF, PNG, JPEG, and ZIP plan sets, with versions available for web, Windows, macOS, Linux, and self-hosted environments. Users can calibrate scales, check dimensions, trace areas and lines, count symbols, define finish conditions, and produce quantity reports. The default application requires no account or upload, while local browser storage and project archive export keep takeoff work on the user's device.

Its strongest capability is the combination of detailed manual measurement and structured quantity logic. OpenTakeoff supports area, rectangle, linear, surface-area, and count measurements, along with finish conditions for waste, multipliers, and material quantities. Symbol sweeps and schedule-based counting extend the workflow beyond basic tracing, while OCR takeoff is included in its category specifications. Reports can be exported as CSV, Excel, JSON, PDF, or DXF, and marked-set PDFs provide a way to preserve annotated plan output. This makes it a practical fit for teams that need flexible measurement and reporting without committing to a paid tier.

The platform also supports AI-agent operation through an MCP server, with compatibility for MCP clients and an integration with Google Drive. That ecosystem fit is useful for teams already working with compatible AI tooling, but it adds a dependency for agent-driven workflows. OpenTakeoff is best suited to users who value open-source software, local handling, and broad export options. Teams looking for a centralized workflow, or a takeoff process built around a fully available one-click area feature, should consider whether the current default build matches their operating model.
