GH Web UI is a Grasshopper plugin for Rhino that enables the creation of HTML and CSS web-based user interfaces and dashboards. This software utility provides a functional bridge between Rhino Grasshopper and web technologies. It allows users to construct custom front-end interfaces, including dashboards and control panels, directly within the Grasshopper environment. By leveraging HTML and CSS standards, the plugin facilitates the display of parametric data and model parameters in a browser-based format. The toolkit includes specific components designed to map Grasshopper outputs to web elements, enabling real-time interaction and visual feedback for complex algorithmic models. It effectively transforms standard parametric workflows into accessible, web-ready applications for broader project stakeholder review.

The download is a 3.2 MB file containing .ZIP files.

To utilize this plugin, install the library into the Grasshopper components folder within Rhino. Once loaded, access the new components via the Grasshopper toolbar to build your interface logic. Connect data streams from your existing definition to the UI components to define the web layout and interactive elements. The plugin compiles these connections into HTML/CSS structures, which can then be previewed or hosted locally to provide a functional dashboard for your parametric model.

This tool is essential for architectural practices and engineering firms developing custom computational tools or automated design configurators. It is well-suited for internal office workflows where complex parametric models require simplified, non-technical interfaces for client presentations or team collaboration. Professionals use this plugin to build interactive project dashboards, automated design tools, or web-based configurators for modular building systems. It pairs effectively with Rhino-based design automation, streamlining the transition from heavy computational definitions to lightweight, user-friendly web interfaces for broader project deployment.
