Polymer vs Tabris Framework

It provides a base component.

HTML markup as it can be a non-string.

It provides Flex layout components.

CSS can be applied far more comfortably than React.

The presence od specialized debugging tools are advertised by competitors. The all features of web components are natively supported by browser embedded development tools.

The router is embedded into CLI for project creation and covers as web as Progressive web app, also fused with Polymer layouts out of the box. The shop template for CLI has a complete solution including the routing.

Full app stack from data tier to routing, progressive web app, responsive layouts makes no need to seek outside of Polymer ecosystem for application features.

In addition to waste set of mature web components in Polymer Elements along with Vaadin Elements there are thousands of web components in the wild comparable to jQuery plugins set.

Polymer guides you as with tools (cli, build environment, app templates,..) as with complimentary documentation on all phases of app development from creation of app as progresive web app to production deployment instructions.

As Polymer is standards based, the whole community around those standards also helping in documentation and support.

Web Components are a collection of specifications released by W3C as a way to reduce the complexity of web apps by creating reusable components. Browser support is currently poor for web components, however Polymer is developed to make web components compatible with modern browsers.

The Polymer APIs are split on application layers and follow standards on all possible ways: Web Components, CSS variables, async API via Promises and so on.

Most Cordova plugins work with Tabris as plug-n-play modules, without any special tuning.

Tabris is very easy to use. You can just download Tabris Dev App from Play Store/AppStore and run any example from GitHub or code snippet from documentation right away using Playground.
