## What it is
Kendo UI Core is the free, open-source subset of Progress Telerik's Kendo UI, an HTML5 and jQuery-based widget library for building modern web and mobile apps. It provides a set of UI widgets (dropdowns, date pickers, list views, calendars, etc.) while advanced components like Grid and Spreadsheet require a commercial license.

## Use cases
- add date pickers and dropdowns to a jQuery web app
- build responsive HTML5 UI widgets without a framework
- add autocomplete and combobox inputs to a legacy jQuery site
- create calendars and schedulers in a JavaScript app
- build mobile-friendly web UI with jQuery widgets
- add list views and pagers to a data-driven web page

## When to choose
- you maintain a jQuery-based web application and need polished, accessible widgets
- you want a free open-source subset of a mature commercial component library
- you need consistent theming and API across many UI widgets
- you are building HTML5/JavaScript apps without a modern SPA framework

## When to avoid
- you need data grids, spreadsheets, or other premium widgets without a commercial license
- you are building with React, Angular, or Vue and want native components rather than jQuery wrappers
- you prefer lightweight, modern component libraries with permissive licenses
- you want full open-source freedom - the license is a mixed open-core model
