Bootstrap Vs Polymer: In Depth Comparison of Advanced UI Frameworks

Responsive web design is mandatory as per the current web design requirements go as it provides engaging user experience across available screen sizes. Our extensive experience in front end development services provides us with the knowledge to identify and recommend an ideal framework with a great value proposition.
Bootstrap and Polymer are both advanced UI frameworks and offer great value to developers. Both of these come with plus and minus of their own, which we have analyzed from various aspects to provide the best possible option.


  1. Maturity: Bootstrap is in the game for quite some time, and over the years, it has improved consistently and boasts better developer community support, whereas Polymer is still in the evolving stage.
  2. Size: Both of these frameworks are large in size, so in this aspect, there is nothing more to differentiate. The large size of Bootstrap makes the first size request more time-consuming. Polymer is also large in size due to the size of its web components but has comparatively low support from native API’s.
  3. Web standards: Bootstrap, as well as Polymer supports most of the web standards. Some of the futuristic web standards, like custom elements, custom templates, are supported by Polymer only.
  4. Designing Tools: Polymer supports design tools that facilitate building prototypes and UI screens, whereas Bootstrap lacks on this front.
  5. Browser Support: Polymer and Bootstrap support both mobile and desktop browsers efficiently. However, browser compatibility is one of the biggest advantages of the Bootstrap, and this provides an edge to Bootstrap over Polymer.
  6. CSS Libraries: Both of these frameworks come with very good CSS libraries. While Polymer has its own set of UI components, Bootstrap depends on third-party libraries.
  7. Data Binding: Polymer has supremacy over Bootstrap as the later one does not support data binding.

Final Words

Though Bootstrap and Polymer seemed almost similar in the features and value propositions, both of these frameworks have been used to develop hundreds of popular web projects, and that can be used as a reference to see which one of these frameworks is more suitable for your requirement.

If higher-level customization and flexibility are your project requirements, then Bootstrap is the aptest choice. Its ready framework lets you work with varied libraries that can be applied as required, not to mention its default elements, ready to use components, and 12 column grid. It is also possible to switch between fixed and responsive grids with just a few changes. Also, Bootstrap CSS is appropriate for the most common uses of digital communication tools for which it has built-in advanced JavaScript functionalities.

Polymer is a new type of library that is built on the advantages of browser infrastructure to provide the extendibility and encapsulation. It is based on some of the latest technologies- custom elements, shadow DOM etc. Polymer is based on new standards and makes the new and advanced features available on other browsers delivering ease of development by removing unwanted coding parts.

Though the choice of the framework is mostly defined by project requirements, Bootstrap is recommended based on the developer community’s views. They chose Bootstrap over any other framework because of its grid layout, well–defined default CSS elements, and advanced JS components that make life easier for developers and ensure consistent user experience across screen sizes and all browsers.
