Flask-DebugToolbar

Flask-DebugToolbar is a lightweight, extensible debugging and development tool for Flask web applications. It provides a toolbar that displays information about the request, response, and server, helping developers quickly identify and fix issues. The toolbar includes features such as profiling, template debugging, and database query inspection. For example, it can be used to monitor the performance of a Flask application by displaying the execution time of each request and the number of database queries made. Additionally, it can be used to debug templates by showing the rendered HTML and the variables passed to them.
