## IFC Viewer SDK

The Flinker IFC Viewer SDK is the fastest way to embed a complete, production-ready IFC viewer into a web application.

- Community tier: free forever with commercial use included, up to 2,000 viewer opens/month, no account required, no npm install
- Import one CDN ES module: `https://cdn.flinker.app/ifc-viewer/v3.3.0/ifc-viewer.es.js`
- IFC files are processed locally in the browser — never uploaded to a server
- Supports IFC 2x3, IFC4, IFC4x3, BCF 2.1 & 3, IDS 1.0
- Works with JavaScript, TypeScript, React, Vue, Angular, and plain HTML

### Quick start (5 lines)

```html
<bim-grid id="ifc-viewer"></bim-grid>
<script type="module">
  import { IfcViewer } from "https://cdn.flinker.app/ifc-viewer/v3.3.0/ifc-viewer.es.js";
  const viewer = new IfcViewer("#ifc-viewer");
  await viewer.ready;
  const bytes = new Uint8Array(await (await fetch("project.ifc")).arrayBuffer());
  await viewer.add("project.ifc", bytes);
</script>
```

### AI coding assistant prompt

```
Add a fully working browser IFC viewer with the Flinker IFC Viewer SDK.
Use this import:
import { IfcViewer } from "https://cdn.flinker.app/ifc-viewer/v3.3.0/ifc-viewer.es.js";

Mount it into a <bim-grid id="ifc-viewer"></bim-grid> element.
Create the viewer with new IfcViewer("#ifc-viewer").
Await viewer.ready before loading files.
Convert IFC, BCF, or fragment files to Uint8Array and call viewer.add(file.name, bytes).
Do not upload the IFC file to a backend just to view it.
```
