What is SquadraCAD
SquadraCAD (pre-alpha) is a parametric 3D CAD that runs in the browser. You draw sketches, turn them into solids with operations, and every step stays editable in a history. It is made for people who need real CAD without installing anything: makers, students, small workshops.

What is it for?
Designing parts you can make: 3D-printed enclosures, brackets, adapters, spare parts, teaching pieces. Anything that starts as a sketch and ends as a solid.
What state is it in?
Early. The modelling core works and is used daily, but features change, some things break, and drawings and assemblies do not exist yet. We say pre-alpha so nobody is surprised.
Who is behind it?
A small independent team in Spain. We answer at [email protected] and publish what changes in the changelog.
Is it free?
There is a free plan with limits that does not expire, and paid plans for more. No card is needed to start.
Is my work safe?
Documents are saved on our server with every change and you can export them at any time. Geometry is computed on your own machine.
Your next part starts in a tab.
Free to start. Nothing to install.
