What is difference between Open UI5 , SAP UI5 and SAP Fiori ?



It is a JavaScript UI library consisting of a feature-rich core and a large number of UI controls which are organized in a handful of libraries.

By “feature-rich” I mean stuff like data binding and models for different data sources, an efficient engine for creating and updating the HTML of the controls, support for a Model-View-Controller concept, support for declarative UI construction and HTML templates, automatic loading of the appropriate language resources and many other features along these lines.

The controls range from simple Button controls to complex ones like the sap.m.SplitContainer (with a responsive master-detail behavior and animated page navigation) and provide support for accessibility, keyboard navigation, touch interaction, right-to-left languages etc. out of the box. Different visual themes are available and can be adapted by either modifying the CSS or using the Theme Designer.

SAP is using this UI library for business applications, where standards like security and supportability are crucial, so protection against cross-site scripting and other attacks and a powerful error analysis/inspection tool is integrated. And for sure SAP is investing a lot into automated and manual tests, from unit tests to screenshot comparisons.

UI5 is based on jQuery, which of course can be directly used in UI5 applications, but there’s a lot on top of it, so most of the time you might rather find yourself working with the controls.

Many other Open Source libraries are used in UI5 and come bundled with it, e.g. LESS, the famous CSS processor, or datajs, the OData library.


Fiori focus mainly on mobility. One code line for all screen sizes.

In summary, SAP Fiori represents SAP’s commitment to delivering a superior user experience, transforming the way users interact with SAP software and enhancing overall business efficiency.


“OpenUI5” is the free version available under the Apache 2.0 Open Source license.

“SAPUI5” is the version that may only be used by SAP customers with a certain kind of license. (It’s still free for them, but they have paid some other SAP product.)

The good news is: most importantly, the entire core of “OpenUI5” and “SAPUI5” (containing all central functionality) is identical. The most-commonly used control libraries, containing the vast majority of all existing controls, are identical. All of this can now be used for free, when using OpenUI5.

The difference is in some more exotic control libraries which have not (or not yet) been put under an Open Source license. There are several reasons, including legal issues, organizational clarifications (developed in different parts of SAP) – and after all SAP is still a company which has to pay its employees, so it may choose not to give everything away for free. You find the same pattern with other Open Source libraries and products.

But anyway, the majority of all things UI5, including all things which have been developed close to the core of it are free. And there are no paid extensions. There is no intention to make any money with UI5.

This was the technical perspective. Beyond that, there is a difference regarding support: for SAP customers with that certain sort of license the “commercial version” SAPUI5 comes with support agreements, so SAP guarantees bug fixing. These support guarantees are naturally not coming with the completely free Open Source version of UI5. But still, it is not a fork or so:OpenUI5 also gets the bug fixes done for SAPUI5. It’s the same thing, just a subset. A big one.


  1. UI5 and Fiori both are developed and owned by SAP.
  2. UI5 is library framework, where Fiori is a design concept.
  3. All Fiori applications are developed using UI5.
  4. All applications developed using UI5 are not Fiori applications.
  5. There are more than 750 standard Fiori applications in Fiori Library.
  6. Without Fiori guidelines, UI5 applications are called as custom UI5 application.
  7. In Fiori Application data is coming from Odata where in custom UI5 application data may be come from any web service. (XSJS, .Net web service , Odata , XSOdata etc).


Fiori applications are the standard or custom applications which are strictly following Fiori guidelines and developed with UI5 framework. Hence there is only one difference i.e. applications which follows Fiori design guidelines are Fiori applications and applications which are not following guidelines are custom UI5 applications.
