Can I vibe code Figma?
Collaborative interface design with real-time multiplayer editing.
You can build a basic vector editor in the browser — shapes, layers, a canvas — as a substantial but doable project. What you cannot vibe-code is Figma: real-time multiplayer where dozens of cursors edit the same file with conflict-free sync, a high-performance rendering engine that stays smooth on huge files, plus components, auto-layout, prototyping, plugins, and the whole ecosystem teams standardize on. The multiplayer engine alone is a deep distributed-systems problem, and the ecosystem is a network effect. The canvas is the easy part; the collaboration and the ecosystem are the moat.
Build a single-user vector design editor that runs in the browser — and be upfront in the README that real-time multiplayer is deliberately out of scope. Use a canvas library (such as Fabric.js, Konva, or a custom SVG layer) to support drawing rectangles, ellipses, lines, and text; selecting, moving, resizing, and rotating objects; a layers panel with reordering; grouping; and fill/stroke controls; plus undo/redo. Add pan and zoom on an infinite canvas, snapping to guides, and export to SVG and PNG. Persist documents locally. Note that Figma's actual moat — conflict-free real-time collaboration and the component ecosystem — is a distributed-systems and network-effect problem you are not attempting here.
A single-user vector/canvas editor with shapes, layers, text, and export — a fraction of Figma with no real-time collaboration.
- Real-time multiplayer editing with conflict-free sync
- A rendering engine tuned to stay fast on enormous files
- Components, auto-layout, variants, and prototyping
- The plugin ecosystem and the fact that your whole team is already there
Figma's value is that an entire team designs in the same file at the same time, with a shared component system, and everyone already uses it. That real-time engine plus the ecosystem is the moat — rebuilding the canvas misses the point, because the point is the collaboration and the network around it.
A prompt is the first move, not the whole game. Course 01 teaches you to take a prompt like this one to a shipped, working app — reviewing, correcting, and steering the agent the whole way.
