Virtuoso Licensing

Virtuoso Licensing Overview

The Virtuoso Core Framework is free to use for development.
Commercial deployment is also permitted — many deployments are royalty-free, while others may include a 5% royalty on gross revenue. Full details are described in the Core Framework EULA and the Virtuoso Pricing page.

This page explains how licensing applies across the Core Framework, No-Code host platforms, host component libraries, and special toolkits.

Virtuoso Core Framework Licensing

The Virtuoso Core Framework software includes:

• Visual programming environment (schematic editor and scalable toolbox of components)
• No-Code host platforms (e.g., C# WPF desktop application host), built as plugin extensions of the Core Framework
• Wizards (Virtuoso component wizard and port wizard)

Although distinct software packages, all of these elements are part of the Core Framework and are licensed under the Core Framework EULA.

Key takeaway:

• Free for development
• Never a cost for internal use and internal deployment
• Commercial deployment: royalty-free in some cases, 5% royalty in others

No-Code Host Platforms

A No-Code host platform (for example, the C# WPF desktop host) is delivered as a plugin extension of the Core Framework.
Because of this, it is also covered by the Core Framework EULA.

Key takeaway:

• Covered by the same rules as the Core Framework (free for dev, possible royalty on deployment).

Host Component Libraries

Host component libraries (such as Virtuoso.StandardLibrary) are licensed under the Virtuoso Host Component End User License Agreement.

Key takeaway:

• Free to use under the Host Component EULA.

Embedded Toolkit Exception

The Virtuoso.EmbeddedToolkit.VS2022 package enables the virtualization of embedded systems hardware. It is an example of “premium content” and is licensed separately.
Please see the Virtuoso Embedded Toolkit End User License Agreement and the Virtuoso Pricing page for details.

Key takeaway:

• The embedded virtualization toolkit is not covered by the Core or Host Component EULAs — check its specific license.
