One software license is required per developer.
Run time royalty free.

Please Note: Kendo UI for Angular and Kendo UI for Vue npm packages now have an additional requirement for developers to provide a license key when adding any of the npm packages to their Angular or Vue projects.
This license is a physical file (in .txt file format) which needs to be included in your project. It can be downloaded from your Telerik Account.

Includes Source Code (excluding JustMock).

Available as 2 license types:

• Annual Subscription License: Flat annual fee including product updates, technical support, and any forthcoming exclusive benefits. The Subscription License must be renewed to continue to use the software.
• Perpetual License: One-time purchase granting access to the current released versions. Includes 1 year subscription of product updates and technical support. After the initial subscription period you can choose to renew the subscription element. If you do not renew then you may continue to use the installed version available during your active subscription term but you will no longer be entitled to product updates or technical support.

What are the other differences between a Subscription and a Perpetual license?

A Subscription license gives you continuous product updates, technical support and access to our full suite of productivity and design system tools. This includes Page Templates, Building Blocks, ThemeBuilder, and modern AI capabilities like AI Coding Assistants and the Agentic UI Generator, helping teams accelerate development, maintain brand consistency, and streamline handoffs. A Subscription plans also include Single Sign‑On (SSO) for easier user management and improved enterprise security.

A Perpetual license is a one‑time purchase that provides access to the current product version along with one year of updates and support. Perpetual users can also explore our AI tools with a 30‑day trial to evaluate how these capabilities might enhance their workflow before considering an upgrade.

Licensed Developers may install the Software on multiple machines, so long as the Software is not being used simultaneously for development purposes at any given time by more Licensed Developers than You have License seats.
