What are the best code review tools or plugins to enhance GitHub’s default PR experience?

I find GitHub’s default pull request UI a bit lacking for detailed code reviews.

Are there any code review tools or browser plugins you’ve used that improve functionality or offer a cleaner, more efficient UX for reviewing PRs directly in GitHub?

@saanvi.savlani Totally agree, GitHub’s default PR view can get cluttered fast.

I’ve been using the Refined GitHub browser extension, and it’s a game-changer.

It adds little UX boosts like collapsing unchanged files, showing CI statuses inline, and more compact diffs.

Also, I pair it with Octotree for a sidebar file tree, it really helps when jumping between files in big PRs.

For teams doing deep reviews, Reviewable.io has been great.

It integrates directly with GitHub but gives you granular control over which lines have been reviewed, and its threading system is clearer than GitHub’s native one.

I also like how it tracks review progress per reviewer.

It’s overkill for small teams but fantastic for enterprise or OSS.

Yep, agreeing to @akanshasrivastava.1121 to Refined GitHub, and if you’re into automation, Danger.js is worth checking out.

It’s not a UI tool, but it automates PR comments based on custom rules (e.g., flagging missing tests, changelogs, or large diffs).

Helps enforce consistency without needing humans to repeat the same feedback.

We also use LambdaTest to run visual regression tests on every PR and automatically post comparison screenshots in the thread, it’s been a big win for front-end QA.
