Introduction Building a real-time collaborative canvas is harder than it looks. The interface seems simple enough, boxes, lines, and cursors moving around. But underneath it is a constant stream of concurrent edits, conflicting updates, and shared state that has to stay consistent for everyone at the same time. The hard part is not drawing on the canvas. It is making sure multiple people can work on the same board simultaneously without things breaking quietly in the background. In this article, we will build a collaborative whiteboard using Velt that supports shared editing, live presence, comments, and AI-assisted interactions all inside the same canvas. The focus is not just on rendering nodes but on wiring the system in a way that keeps every user in sync without adding friction to the experience. Here is what the final result looks like. Now let's look at the stack behind it and how each piece fits together. The Stack Next.js for the app framework ReactFlow for the infinite canvas
