An OpenFin Application Framework
Quickly assemble desktop applications from HTML5, .NET, and Java components.

Make HTML5 Desktop Applications a Reality

HTML5 is the modern way to build powerful and beautiful applications. With Finsemble, developers can quickly assemble desktop applications that support multiple windows, multiple monitors, menus and dialogs – all using HTML5, built on top of OpenFin.

Flip the paradigm. Scrap your legacy container and move to a pure HTML5 container that also supports .NET, Java, and Flex components. 

For Developers


For Users


The UX Layer for Your Container

Web toolkits are designed for building “single page” applications. Desktop applications are inherently more complex, and require a new set of tools previously unavailable in HTML5.

Finsemble provides multi-window layouts, which allow users to organize their desktop into saved workspaces – even across multiple monitors. Components can communicate across window boundaries. They can synchronize and exchange data. Developers can finally break out of the single page paradigm.

Finsemble extends HTML5 with APIs that accelerate your desktop application project:

  • Window management
  • Workspace management
  • Dialogs, Menus and Launchers

Many organizations suffer from a fragmented environment with dozens or even hundreds of apps running in React, Angular, .NET, Java, or Flex. Finsemble unifies the user experience and streamlines application management, giving full control back to developers and product managers.

The Open Alternative to the Terminal

The desktop has been siloed for too long: market data lives in one container, third party apps in the browser, and in-house software on its own.

Finsemble is an open framework that unifies the desktop and provides the cohesive experience of a proprietary terminal, but with your choice of third party and in-house applications. Use your own market data or a range of third-party providers. No vendor lock-in. No proprietary app stores. Your desktop for your users.
