Btr

btr is a developer-oriented Chrome extension designed for debugging, inspecting, and analyzing browser behavior during web application development. The extension provides tools for observing browser tabs, network requests, cookies, and internal browser state in real time. It is intended for local development and debugging workflows and helps developers better understand how web pages and requests behave inside the browser. btr can monitor network requests using Chrome’s webRequest APIs, access tab information, and read cookies associated with active tabs. These capabilities are used strictly to display debugging information and assist in development tasks. For debugging purposes, the extension may send technical data (such as request metadata or diagnostic information) to a local server running on the user’s own machine (for example, localhost or 127.0.0.1). This communication happens only within the local environment and is not transmitted to external or remote servers. The extension does not collect personal user data, does not track browsing activity for analytics or advertising, and does not share any data with third parties. All processing is performed locally in the browser or on the user’s local machine. btr does not use remote analytics, advertising services, or external APIs. Any locally stored data is used only to support the extension’s functionality and can be removed at any time by clearing browser storage or uninstalling the extension. This extension is intended for developers, testers, and advanced users who need deeper visibility into browser behavior during development and debugging.
