Nixpkgs PR Tracker is a Chrome add-on designed to enhance the efficiency of monitoring pull requests (PRs) in Nixpkgs. This free tool seamlessly integrates with the GitHub interface, adding a crucial feature that displays the branch into which a PR has been merged directly on the PR page. This improvement helps developers quickly identify the status of their contributions without navigating through multiple pages or repositories.

In addition to its core functionality, Nixpkgs PR Tracker offers the option to provide a GitHub token, which is particularly useful for users who encounter rate limiting issues while accessing GitHub. This feature ensures that users can consistently track their PRs without interruptions, making it an essential tool for those actively involved in Nixpkgs development.
