For inspecting Lightning apps
The Salesforce Lightning Inspector opens up and improves your Lightning Component development, giving you access to a wealth of data about your running applications and components.
With the Salesforce Lightning Inspector you can:
- Easily inspect and navigate the structure of your components
- Identify performance bottlenecks by looking at a graph of component creation time
- Debug server interactions faster by monitoring and modifying responses
- Navigate the component tree, inspect components and their associated DOM elements
- Track event firing and handling sequences
