Paper

Paper is a code-native design tool where every element on the canvas is real HTML and CSS — what you design is what ships, with no conversion step. Its MCP server exposes 24 bidirectional tools so AI agents can not only read your design but modify it: sync tokens from Figma, populate UI with live API data, or convert a design into React/Tailwind and commit to GitHub. The Snapshot Chrome extension (March 2026) lets you paste any live website into the canvas as editable HTML/CSS layers, so you start from production rather than a blank slate. May 2026: QuiverAI’s Arrow 1.0 model (a16z-backed, #1 on SVG Arena) is now integrated — generate and edit real editable SVG assets directly in the canvas. July 2026: Paper Shaders — their standalone WebGL effects library — went fully open source (Apache 2.0), free for commercial use. Raised $34M Series A led by Accel and ICONIQ (with Designer Fund, Michael Grinich, Anton Osika) in July 2026 on 25x ARR growth since early 2026. Built by Stephen Haney, formerly of Modulz/Radix UI; $20/month ($16/month annual).
