Tip OpenUI5, an open source version of the UI development toolkit for HTML5, is available at published on non-SAP site.

SAPUI5 is a client UI technology based on JavaScript, CSS and HTML5. SAPUI5 applications run within a browser.

Servers come into play for deploying your applications, storing the SAPUI5 libraries, and connecting to a database. Depending on the environment in which you are using SAPUI5, the libraries and your applications are stored for instance on an SAP NetWeaver Application Server or an SAP HANA Cloud Platform. The preferred way to access business data for your application is by using the OData model through an SAP Gateway.

When users access an SAPUI5 application from their device, a request is sent to the respective server to load the application into the browser. The view accesses the relevant libraries. Usually, the model is also instantiated and business data is fetched from the database.

The SAPUI5 runtime is a client-side HTML5 rendering library containing a rich set of standard and extension controls. It provides a lightweight programming model for desktop and mobile applications. Based on JavaScript, it supports Rich Internet Application (RIA) like client-side features. SAPUI5 complies with OpenAjax and can be used together with standard JavaScript libraries.
