Can I code Figma?

COPYDon't rebuild Figma's canvas rendering engine — audit whether you need the paid seat before building anything at all: list what you actually do in it (solo mockups, team handoff, prototyping), map each to an existing free tier's limits and to open-source vector editors, and only build something if a real gap remains. If the real gap is 'describe a UI, get working code' rather than a canvas to draw on, build a component playground instead: a text input where you describe a UI, a call to an existing LLM API with your design system's actual component library in the prompt context, and a live preview rendering the generated code against your real components (not a mockup image). That's a genuinely achievable weekend project, and for a growing share of real workflows it replaces canvas time entirely. Out of scope: the custom WebGL/WASM rendering engine itself, real-time multiplayer cursors and presence on an infinite canvas, and the plugin/library ecosystem — all genuinely deep, ongoing engineering investments, not weekend features.
