Online Collaboration Whiteboard Development

I’m building a browser-based whiteboard whose single purpose is smooth, real-time collaboration. Think of a shared canvas that multiple people can draw, write, and brainstorm on together without lag, no matter where they’re located.

Here’s what I need from you:
• A responsive web application that opens in any modern browser and updates instantly for every connected user.
• Core drawing tools (pen, shapes, text), unlimited canvas or paging, and intuitive pan / zoom so sessions stay fluid.
• Secure, room-based access with simple links or codes, plus a way to clear or export boards (PNG or PDF) when a session wraps up.
• Clean, well-documented code and deployment notes so I can host it on my own server when development is complete.

You’re welcome to suggest extras—maybe file drops, screen sharing hooks, or lightweight video chat—so long as the live sketching stays lightning-fast. Tech stacks such as React, Vue, or vanilla JS with WebSockets or WebRTC for syncing are all fine by me; pick what you’re strongest in and explain why.

I’ll review milestones based on:
1. A working demo URL.
2. Code hand-off with comments and README.
3. Final deployment assistance.

If you’ve built interactive whiteboards, multiplayer canvases, or related real-time tools before, please link a sample. Let’s create a collaborative space that feels as natural as scribbling on a physical board—only better.
