HTTP Header Tracker is a Chrome add-on designed to collect and analyze HTTP header statistics while prioritizing user privacy. This free tool operates locally on your device, ensuring that data remains private and secure. It automatically anonymizes sensitive information such as auth tokens and cookies, making it a reliable choice for users concerned about their online privacy.

Key features include the ability to export data in JSON format or clear it as needed, along with a local-only storage option that prevents external connections. Additionally, users can configure an optional server mode to aggregate data across multiple devices. The tool collects header names, values, and frequency counts while avoiding the collection of URLs or personal information, providing a focused solution for monitoring HTTP headers.
