BenchUp offers free, open-source 3D modeling for woodworking in browser or desktop
A new tool lets users design furniture with precise measurements without accounts or cloud storage.
Key points
- BenchUp runs on Windows, macOS, Linux, and desktop browsers via WebGPU or WebGL2.
- The application supports importing SketchUp geometry and exporting OBJ files.
- Projects autosave locally with no requirement for user accounts or cloud connections.
A trending discussion on Hacker News highlighted BenchUp as a free, open-source application for 3D modeling focused on woodworking and furniture design.reported The project documentation describes the tool as usable on Windows, macOS, Linux, and directly within a desktop browser.Users can design furniture online for free without signing up or installing software.The application leverages WebGPU for client-side 3D rendering with local file persistence. It requires no user account to operate.

How we got here
The application targets woodworkers, furniture makers, and DIY builders who wish to explore projects in three dimensions before physical construction. Users can plan shelves, tables, cabinets, or workbenches with exact measurements. The interface prioritizes keeping essential tools close while centring the model.
What is new
Documentation outlines capabilities including sketching lines, rectangles, circles, and freehand outlines. Faces can be extruded using a Push/Pull function, then moved, scaled, offset, or painted. Geometry snapping to axes and typing exact lengths are supported for precision.
What to watch
Users can organize complex assemblies using groups, reusable components, and tags. The Tape Measure and Dimensions tools allow inspection of the design. Orbiting around the assembly helps review proportions before taking measurements to a workshop environment.
Availability and limits
Access is free and open-source. The application runs on devices with hardware acceleration supporting WebGPU or WebGL2.reported A mouse and keyboard are required for modeling. Autosaving occurs locally in the browser; clearing browser data removes work, so downloading .ketchup project files is advised. No cloud storage exists.

Why it matters
- Developers can integrate local-first 3D editing workflows without managing user authentication systems.
- The support for SketchUp imports and OBJ exports provides interoperability with existing 3D pipelines.
- Browser-based access via WebGPU reduces distribution barriers for desktop-class modelling tools.
- Local autosaving and explicit lack of cloud storage address privacy concerns for sensitive designs.

The strongest doubt
Counterpoint from the sources
Clearing browser data can remove autosaved work, meaning local persistence depends on user discipline to download project files.
