Nucleo
What Nucleo is
Nucleo is an icon library with a web app, native desktop tools, and AI coding integrations. Its web app lets users browse, copy, and customize 44,282 icons. Mac and Windows apps organize icons, provide access from design tools, and export SVG symbols, icon fonts, JSX, Vue code, and other formats. The beta MCP server and agent skills let AI coding tools search licensed icon families, insert React or Vue components or SVGs, and customize icons in chat. The documented CLI supports Cursor, Claude Code, and Codex and requires Node.js 20 or later. Free icon families can be installed through the AI integration without an account, while private React packages require a license key and offer free previews of essential packages. Collections are sold with one-time prices from $69, including an All Icons Bundle at $149. Commercial use is allowed, and standard licensing limits project usage.
