Ionic

Cross-platform UI toolkit for building native-quality iOS, Android, and Progressive Web Apps with HTML, CSS, and JavaScript. Ships a single codebase across app stores and the web, targeting web developers who want to reach mobile without learning Swift or Kotlin.

Trusted by enterprises and powers a significant share of App Store and Google Play downloads, especially with Angular. Ionic differentiates by supporting React, Angular, and Vue with official integrations while remaining framework-optional, using Web Components at its core for stable, vendor-neutral APIs. Millions of developers use the toolkit across more than 200 countries, with active community forums and regular meetups.

Key capabilities:

• 100+ UI components with adaptive styling that match iOS and Android platform conventions
• Official integrations for React, Angular, and Vue, or use standalone with no framework
• Capacitor bridge for native deployment and access to device APIs such as Camera, Filesystem, and Share
• CLI for scaffolding, local dev server, hot refresh, and cloud builds
• Built-in theming with light and dark mode, hardware-accelerated transitions, and touch-optimized gestures

Teams use Ionic to build consumer and enterprise mobile apps from existing web skills, ship PWAs alongside native binaries from the same codebase, and prototype or iterate quickly without separate iOS and Android projects.
