Why Capstart?
Most UI libraries are designed for the web and retrofitted for mobile. Capstart is different — it's built from the ground up for hybrid native apps powered by CapacitorJS.
Native-first design
Every component respects the interaction patterns and visual language of iOS and Android, giving your users a genuinely native feel.
The largest collection
From action sheets and toasts to bottom sheets and haptic feedback — the broadest set of CapacitorJS-compatible UI components in one place.
Built on Capacitor plugins
Components integrate seamlessly with the official Capacitor plugin ecosystem, so you get real native APIs, not browser shims.
Fully themeable
CSS variables and design tokens let you match your brand perfectly. Light and dark mode work out of the box.
Comprehensive docs
Each component comes with live examples, prop tables, and copy-paste code snippets so you can ship fast.
Ship with live updates
Do not wait 2-3 days for App Store review to ship a web-only change: use a live update when the native shell is unchanged.
