GitHub Pulls Show Reviewers, a Chrome extension by shun-shun, adds reviewer assignment visibility to a repository's pull request list view to reduce navigation. It inserts reviewer profile icons into the list and updates as the page changes, so you do not need to open each pull request to check assignments. The extension works across repositories and activates without configuration, making it useful for developers, tech leads, and project managers tracking multiple PRs.

How it affects browser resource use during review sweeps

Minimal runtime footprint is the extension's stated behavior: it runs as a background script and is designed to avoid noticeable delays in page load times. That implementation means the extension adds DOM updates on the pull request list without running heavy local processing, which keeps additional CPU and network work to a minimum during brief review sessions.

What it does with page data and access permissions

Page-level permissions are required to read and change GitHub pages so the tool can render assignment details in the UI, and the developer specifies it does not access or store repository source code. This design limits data handling to the browser session and the loaded pages rather than transmitting repository contents to external servers.

Which GitHub environments and browsers it supports

Broad Chromium compatibility is available: the extension targets Google Chrome and other Chromium-based browsers, explicitly including Microsoft Edge, Brave, and Vivaldi. Support for GitHub Enterprise is conditional; operation depends on the instance URL structure, so behavior can vary between enterprise deployments and github.com.

How it fits typical code-review workflows

Meant for quick oversight rather than deep review, the tool is positioned for people who scan many pull requests and need assignment context before opening threads. The UI approach aims to blend with GitHub's native styling so the list view remains familiar, which helps teams preserve existing review habits while adding a compact assignment layer.

A practical add-on for individuals and small teams, with a rollout caveat

Developer reception in the community is generally positive, making this extension a low-effort option for contributors and small teams who want faster visibility of assignment status. Larger organizations should pilot it on a few repositories first because enterprise instances and customized URL setups can affect behavior. Try the extension on a noncritical repo before broad deployment to confirm compatibility with your environment.
