Reviewable: The "Power Tool" for Serious GitHub Code Reviews

What is Reviewable?

Reviewable is a specialized code review interface designed for teams that have outgrown the native GitHub Pull Request UI. Founded by former Google engineers who were frustrated with the "state of the art" in 2015, it operates as a sophisticated layer on top of GitHub, focused on two principles: efficiency and thoroughness.

Unlike standard tools, Reviewable doesn't just show you a diff; it tracks exactly where every participant stands in every discussion. It ensures that no comment is ever lost or "pushed away" by a new commit, keeping the focus on high-quality code rather than administrative busywork.

Key Features for 2026

• Intelligent Line-Mapping: Never review the same code twice. If you comment on a line and the author rebases or amends the commit, Reviewable automatically maps your comment to the new location.

• Custom Completion Conditions: Go beyond "one approval needed." You can write small snippets of code to define exactly when a PR is ready to merge—such as requiring specific file-owner approvals or automated test passes.

• Net Delta Tracking: See exactly what has changed since the last time you looked at the code, even if the author has pushed dozens of intermediate commits.

• "Blind" Review Support: To reduce bias, you can configure reviews where collaborators cannot see each other's comments until they have submitted their own.

• File Grouping & Hiding: Automatically collapse or group "vendored" files, generated code, or minor whitespace changes to keep your review focused on the logic that matters.

• Seamless GitHub Sync: All comments and approvals made in Reviewable are instantly synced back to the native GitHub PR interface, ensuring your repo remains the single source of truth.

Frequently Asked Questions

Does Reviewable replace GitHub?

No. Reviewable is an interface that sits on top of GitHub. You still host your code on GitHub and use its actions and permissions; Reviewable simply provides a more powerful environment for the actual code review process.

Why is the UI different from GitHub?

Reviewable is built as a "power tool" for developers who spend hours every day reviewing code. While the learning curve is slightly steeper than GitHub’s native UI, it is designed to maximize productivity by reducing "notification fatigue" and unnecessary scrolling.

Can I try it for free?

Yes. Aside from the permanent free tier for public projects, Reviewable offers a 30-day free trial for organizations to test its advanced logic on their private repositories.
