Description
I created Inkflow, a collaborative whiteboard to design LLD & HLD diagrams. This idea came from me designing system architectures and finding myself wanting a simple way to visualize, collaborate, and discuss designs together. - Features - Infinite Canvas - Real-Time Collaboration enables everyone to work on the same board at once - Rooms make separate boards for different designs - Canvas Tools let you draw, connect, and add text freely - Real-Time Sync

Could you build this?
Partial While basic infinite canvas templates exist, building a performant, reliable real-time collaborative whiteboarding tool with conflict-free data synchronization requires complex distributed systems work.
What it would actually take: The architecture needs an infinite canvas rendering engine (Pixi.js, WebGL, or Canvas API) paired with CRDTs (like Yjs or Automerge) over WebSockets for conflict-free multi-user state synchronization. Handling high-frequency pointer updates, shape geometry, and undo/redo stacks without stuttering requires deep frontend graphics optimization and distributed concurrency engineering.
