An Open Terminal

Closed terminals are monolithic solutions that have remained dominant because they own and control your workspace and workflow, but they are outdated and expensive.

Finsemble is the first open framework that allows firms to quickly and easily deploy multi-component desktop applications.

Imagine all the tools within your workflow—legacy, modern, and third-party—working together in a smarter, unified, and tailored desktop experience.

What is an Open Terminal?

An Open Terminal has the specific tools you choose – assembled and integrated – and delivers customizable workflow experiences to the front, middle, and back offices.

 Take Control

Reduce your dependency on rigid and generic proprietary terminals.

 Build Forward

Integrate legacy (.NET, Java, and native code) components into your HTML5 desktop strategy.

Trailblazing HTML5 Functionality on the Desktop. 

The open terminal is delivered through the power of HTML5 functionality and its inherent openness. Choose exactly which applications you want in your terminal space and leave out anything that isn’t critical to productivity. Multiple window components, each running independently, can now be organized into systematic, synchronized workflows.

The open terminal facilitates customizable workflows by leveraging external APIs:


Personalized toolbar, launcher, dialog, dropdowns


Drag and drop to transfer and share data between windows


Save and restore workspaces


Sync windows by symbol or account

Powered by new HTML5 functionality:



Launch and manage native applications written in any language


Scalable, cross-window data binding


Turbocharged performance


Communicate between components

Scale & Interoperate Quickly

Client-side integration is a revolutionary new way to think about interoperability, made possible by Finsemble’s APIs and HTML5 techniques. Client-side integration is a quick performing interaction and data exchange between components using pure JavaScript. Integrations that were once only possible through painful network and infrastructure overhauls now quickly deploy and scale thanks to the Finsemble framework.

  • Combine disparate technologies like native code or languages such as React, Angular, or JQuery with HTML5.
  • An alternative to expensive server-side integration efforts.
