About

Canvas UI Kit

Features
Read full description

Canvas is a universal React Native UI kit, and this is its reference app: the same component library running natively on your device rather than described in a web page. Browse the full catalog of components, from buttons and inputs through data tables, calendars, and charts. Every entry pairs a live, interactive example with its complete prop reference, so you can tap, type, drag, and toggle each control to see exactly how it behaves before you write any code. WHAT IS INSIDE - Live examples for every component, running as real native views - Full prop tables, generated from the library's own TypeScript source - Design tokens for color, typography, spacing, and layout - Templates and patterns showing how components compose into real screens - Instant search across the entire catalog - Light and dark themes, plus a glass surface mode BUILT THE WAY iOS EXPECTS Canvas components follow iOS design conventions, driven by a single component API. This app is the clearest way to see that: it is built entirely from the library it documents. Canvas is free and open source under the MIT license. No account, no sign-in, no ads, and no tracking of any kind.
