ConsoleJSON – pretty styles in the browser console

In plain words

ConsoleJSON is a browser tool that enables developers to apply visual styling to messages displayed in the browser console. Launched in 2015, it allows users to format console output with custom styling options for better readability and organization during development and debugging. The tool is designed for web developers who work regularly with browser consoles and want to enhance the visual presentation of their logged data and messages.
