Hey Product Hunt I built plyxui because I got tired of rewriting the same Button, Input, Stack, Text, Modal every time I started a new project. Especially when the same team wanted a web app AND a React Native app AND a VS Code extension: the primitive mismatch triples across those targets. plyxui ships one primitive surface (Box, Input, Button, Stack, Text, plus composites) with three rendering adapters underneath. Same names, same props. What differs is what they render into: a DOM button on web, a Pressable on native, the VS Code extension host's own tokens for extensions. Two things I want to call out beyond the cross-platform story: 1. Per-package install. You pull only what you need : @plyxui/primitives, @plyxui/comps, @plyxui/layouts, @plyxui/hooks, and so on. No 400kb "just install everything" bundle. 2. First-party MCP server. If you code with Claude, Cursor, Copilot, or any agent that speaks MCP, plyxui exposes its components as tools the agent can call by name. The AI scaffolds screens using the actual library primitives, not its best guess at what "a modal" means. Everything is MIT licensed. The playground on plyxui.com is the real npm package running in your browser : fork it, break it, PR it. If this resonates, I would love your support today. Comments matter more than upvotes: the API surprised you? The docs missed something? A component you always wished existed? Drop it below. I am reading every one live. Thanks especially to the folks who tested early builds and told me what was wrong before it was public. You know who you are.
