Show HN: Opus 5.5 made a fully featured Figma clone in 3 hours / 8 prompts
Mana demo says Claude Opus 5.5 built a collaborative Figma-like editor in eight prompts.
A Mana Show HN post says Claude Opus 5.5 built a collaborative Figma-like design editor on October 9 in eight prompts and under three hours of working time. The editor, about 8,200 lines of React, includes auto-layout, components, vectors, prototyping, live cursors, and support for files around 20,000 layers, while Mana supplied sign-in, storage, hosting, and collaboration. A later prompt replaced the SVG renderer with a tile-based Canvas engine that, in a local headless Chrome test, panned a 51,000-layer file in 21 ms versus 875 ms. Variants, component properties, styles, variables, and Smart Animate are still absent.
