LiveDebugger is a browser-based debugging tool for Phoenix LiveView applications. It helps Elixir developers inspect LiveView behavior while the application is running in development. The tool can show the LiveComponents tree, view assigns, inspect elements, and trace callback execution. It is designed to make LiveView debugging more visual and easier to understand than relying only on logs or manual inspection. LiveDebugger can be installed as a development dependency and also offers browser DevTools extensions for Chrome and Firefox. Its main value is giving Phoenix LiveView teams a dedicated debugging experience for understanding component state, callbacks, and runtime behavior.
