Marionette Inspector
A browser extension for inspecting and debugging Marionette.js applications directly within Chrome or Firefox DevTools.
What is Marionette Inspector?
Marionette Inspector is a browser extension that adds a dedicated panel to Chrome and Firefox DevTools for inspecting and debugging Marionette.js applications. It provides tools to visualize the view hierarchy, track application activity, and inspect components like views, models, and Radio channels, making it easier to understand and troubleshoot complex Marionette-based frontends.
Frontend developers building applications with Marionette.js who need a powerful debugging tool integrated into their browser's developer tools.
Developers choose Marionette Inspector because it offers a specialized, integrated debugging environment for Marionette.js that goes beyond standard DevTools, providing visual insights and direct inspection capabilities that streamline debugging and reduce the need for manual code tracing.

Use Cases
Best For
- Debugging complex view hierarchies in Marionette.js applications
- Tracking application state changes and event flows in real-time
- Inspecting Marionette Radio channel communications
- Understanding the structure of an existing Marionette codebase
- Identifying memory leaks or performance issues in Marionette components
- Learning Marionette.js by visualizing how an application is constructed
Not Ideal For
- Projects not using Marionette.js, as the inspector is tightly coupled to that framework and provides no value for other libraries like React or Vue.
- Teams with minimal client-side JavaScript or server-rendered apps, where standard browser DevTools offer sufficient debugging without additional extensions.
- Applications built with modern module systems like ES6 imports that require careful setup to avoid hoisting issues, adding complexity to integration.
Pros & Cons
Pros
Adds a dedicated Marionette tab directly in Chrome and Firefox DevTools, offering a seamless debugging workflow without external tools, as emphasized in the philosophy.
Provides UI tree visualization, activity history, and detailed inspection of views, models, and Radio channels, making complex app structures transparent and easy to debug.
Includes an inspector magnifying glass for direct component interaction and intelligent source panel links, enhancing real-time debugging efficiency.
Supported by a Gitter chat and encourages contributions with help-wanted tickets, indicating ongoing maintenance and community engagement.
Cons
Only useful for Marionette.js projects; it provides no debugging capabilities for other JavaScript frameworks, limiting its broader applicability.
Requires manual code insertion and careful ordering for non-global setups like Webpack or ES modules, with noted hoisting issues that can break functionality.
Screenshots and some documentation references are from 2014, suggesting the tool may not be actively updated for the latest browser or Marionette versions.
