Why this exists
Offline should mean your modeling workflow still works when the internet does not.
A lot of easy-entry CAD is browser-first, while many full professional tools bring more complexity than a small bracket, enclosure or repair part needs. Glassforge focuses on direct local modeling, real CAD geometry and the export formats makers use around 3D printing.
Real solid geometry
OpenCascade B-rep geometry gives Glassforge a real CAD foundation for booleans, fillets, chamfers, shells and STEP workflows.
3D-printing workflow
STL checks, lay-flat tools, tessellation presets and separate STL export keep the path to the slicer straightforward.
Windows + Linux
The founder purchase currently includes a verified portable Windows x64 package and a verified native Arch Linux x86_64 build.
Built around real maker jobs

Questions before buying
Does Glassforge require an internet connection to model?
No. The core desktop workflow is designed to run locally. Payment and download obviously require internet access, but modeling itself is not tied to a cloud session.
Can it export STL?
Yes. Glassforge supports STL export and also works with STEP, IGES and OBJ, with SVG/DXF sketch interchange in the current codebase.
Is this browser CAD?
No. Glassforge is a native Qt 6 desktop application built on OpenCascade geometry.
Which platforms are available today?
The founder delivery currently includes Windows x64 and Arch Linux x86_64 builds.
