Prism: Advanced multi-panel workspace manager for Plotly Dash

Dash Prism

A multi-panel workspace manager for Plotly Dash applications.

Documentation: https://ludwigaj.github.io/dash-prism/ · PyPI: https://pypi.org/project/dash-prism/

What is Dash Prism?

Dash Prism provides a unified workspace where multiple Dash layouts coexist as tabs within resizable, splittable panels. Users arrange their workspace via drag-and-drop while developers focus on building content.

The Problem

Building dashboards with Plotly Dash typically means:

• Fragmented applications - Each dashboard lives in isolation, requiring users to switch between browser tabs or navigate complex menus.
• Repetitive UI work - Developers spend time on layout scaffolding, tab systems, and panel management instead of business logic.
• One-size-fits-all layouts - Users get a fixed arrangement that may not match their workflow.
• No personalization - Workspaces reset on every visit; users cannot save their preferred view.

The Solution

Dash Prism addresses these issues by providing:

• Unified workspace - Register any number of layouts; users open them as tabs in a single interface.
• User-driven design - Drag tabs to split panels, resize areas, and rearrange freely. Developers define content; users define structure.
• Persistence - Workspace state saves to localStorage, sessionStorage, or memory so users return to exactly where they left off.
• Minimal boilerplate - A decorator-based API keeps layout registration concise and readable.

Installation

@dash_prism.register_layout(id='analytics', name='Analytics')
def analytics():
