Adev Logger is a free Chrome extension designed for developers to effectively capture and inspect API network activity from the active tab. It provides a focused developer UI that displays fetch and XMLHttpRequest traffic in an organized format, making it easier to analyze web requests. This tool showcases essential details such as URL, method, status, duration, headers, request payload, and response data, all presented in a JSON-friendly manner.

Key features include endpoint grouping, filters for method/status/search, one-click copy actions, and sensitive header masking with a reveal toggle. Additionally, it offers clear and refresh controls along with request replay support, enhancing both debugging and API testing workflows. Built with modern web technologies, Adev Logger operates entirely locally, ensuring user data privacy without reliance on external backends.
