Core Features

Private by Design
No account, subscription, ads, tracking, third-party analytics, or developer-operated backend. Core features work offline, and your work stays on device unless you deliberately share or export it.
Use It Responsibly
Preflight and communication aid only. Fabricator rules, impedance, stackup, net intent, and electrical correctness require the source CAD design and manufacturer review.
