What is online-gencad-viewer?

This TypeScript app is a gencad online viewer that loads GenCAD (.cad) PCB files directly in the browser, rendering multi-layer layouts with routing, pads, vias, silkscreen, and board outlines. Drag-and-drop files to explore layers via toggles, filter elements like components or nets, search lists, and highlight selections with auto-pan and properties display. It builds to a single self-contained HTML file using Vite—no server or installs needed for instant sharing.

Why is it gaining traction?

Unlike desktop PCB tools requiring heavy installs, this online gencad viewer runs offline in any browser, with smooth wheel zoom, drag-pan, and bilingual UI for quick multi-layer inspections. Interactive features like net/component search and click-to-highlight beat basic text parsers, making PCB feedback loops faster without online github editor distractions. From EasyEDA, it handles real GenCAD exports cleanly, standing out for zero-setup CAD files visualization.

Who should use this?

PCB designers exporting GenCAD from tools like Altium or KiCad for quick reviews with clients or fab houses. Hardware engineers sharing routing and silkscreen layers in pull requests, avoiding bloated viewers. Teams needing a lightweight online alternative to full PCB suites for pads and multi-layer checks during design handoffs.

Verdict

Grab it if you deal with GenCAD files regularly—solid interactive viewer at 1.0% credibility from 19 stars, with good docs and Apache license, but low adoption signals early maturity; fork or watch for production hardening. (198 words)
