Browser-native document, CAD, and file infrastructure for private web applications.
We build open-source viewer engines, framework components, and delivery tools for teams that need to preview complex files without server-side conversion.
| Area | Focus |
|---|
| File preview infrastructure | Office documents, PDF/OFD, CAD drawings, archives, email, ebooks, code, media, 3D, geo, and structured data in the browser. |
| Framework components | Vanilla JS, Web Components, Vue, React, Svelte, jQuery, and legacy-framework packages powered by a shared TypeScript core. |
| Specialized engines | CAD, DWF/DWFx/XPS, DOCX editing, spreadsheet rendering, AI-ready document context, and private deployment tooling. |
| Delivery products | Source, license, digital asset, short link, QR, and support workflows for independent developers and small teams. |

- Browser first: static deployment, local parsing, worker/WASM loading, and private-file friendly workflows.
- Offline ready: no runtime dependency on third-party CDNs for core viewing capability.
- Integration friendly: framework-neutral core plus native packages for mainstream frontend stacks.
- Production minded: real business files, large documents, predictable APIs, and self-hosted deployment paths.
- Clear boundaries: each repository should document its package name, build output, license, and intended integration route.
For document preview, CAD rendering, and private file workflows, start with File Viewer.
