Overview

CAD-Viewer.org is a free, web-based platform that enables users to view and share CAD files directly from their browser—no software installation required. Designed for both hobbyists and professionals, the platform offers a fast, reliable, and easy-to-use experience across all devices.

Our goal is to make CAD viewing and sharing truly accessible by providing a streamlined, out-of-the-box solution that works anywhere, anytime.

Technology and Source Code

CAD-Viewer.org is built using a combination of open-source technologies and proprietary software. We rely on established libraries such as OpenCascade and X3DOM to deliver robust CAD processing and rendering capabilities.

While the core of our software remains proprietary, we support the open-source ecosystem by contributing bug reports, fixes, and improvements to the third-party projects we rely on. Additionally, you may find on GitHub , selected components that we publish from of our own codebase as free software.
