About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

Onsen UI is a framework for PWA and hybrid mobile interfaces built around Web Components. Its framework-agnostic core includes flat iOS-style and Material Android-style components, with additional bindings for React, Vue, and Angular.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Key features

Compose mobile-oriented interfaces with Web Components

Custom elements and CSS components for pages, toolbars, lists, buttons, navigation, and related UI let applications build mobile-style screens from HTML and JavaScript.

Sources: [2]

Use platform styling and optional framework bindings

The component set includes flat iOS and Material Android designs with platform-aware styling, while separate packages integrate the API with React, Vue, and Angular.

Sources: [2]

Best fit

Fits Cordova-style hybrid apps, PWAs, and maintenance of existing Onsen UI applications

It is useful when a project wants one web-technology UI layer across iOS and Android, particularly for hybrid applications or existing Onsen UI codebases.

Before adoption

Validate current browsers and WebViews instead of relying only on the historical support table

The README lists broad legacy support such as Android 4.4.4+ and iOS 9+. New adoption should still test the actual target browsers and embedded WebViews.

The GitHub release and master package version do not currently match

The latest GitHub release is 2.12.8 while the core package metadata on master declares 2.12.9. Pin the installation version and verify APIs and changelog against that exact release.

Supplemental curator note

Its framework-agnostic Web Components core remains useful for hybrid mobile interfaces, but new adoption should validate the exact package version and target WebViews. The core onsenui package is Apache-2.0 licensed.

Try it in 3 steps

  1. 1

    Install the Onsen UI core package

    Add the framework-agnostic core package using the npm command from the official README.

  2. 2

    Import JavaScript and styles

    Load the Web Components implementation plus the core and component styles from the application entry point.

    import 'onsenui'; import 'onsenui/css/onsenui.css'; import 'onsenui/css/onsen-css-components.css';
  3. 3

    Render an Onsen UI component

    Add custom elements to the page and verify platform styling and component behavior in the target browser or WebView.

    <ons-page><ons-toolbar><div class="center">Demo</div></ons-toolbar><ons-button>Tap me</ons-button></ons-page>
