How we chose the best code review platforms for development teams

Your code review tool should do more than display diffs. It should help your team move faster, share knowledge, and catch issues before they snowball into production incidents.

We evaluated dozens of platforms using criteria that matter most to working developers and engineering leads. Here is what we measured:

• Pull request management: Can you create, review, approve, and merge PRs without bouncing between multiple browser tabs?
• Collaboration workflows: Does the platform support inline comments, code suggestions, and early feedback before a full PR is opened?
• Version control integration depth: How well does it connect with GitHub, GitLab, Bitbucket, and Azure DevOps?
• AI-assisted review capabilities: Does it use AI to surface risk, summarize changes, or reduce review noise?
• Multi-repository visibility: Can you track PRs, issues, and review status across multiple repos from a single view?
• Security and access controls: Does it support SSO, audit logging, and role-based permissions for enterprise teams?

The 5 best code review platforms for development teams

1. GitKraken: Best overall code review platform for development teams

GitKraken takes a collaboration-first approach to code review. Instead of treating reviews as isolated diff-reading sessions, the GitKraken DevEx Platform connects PR workflows, issue tracking, and multi-repo management into a unified experience trusted by over 40 million developers.

The platform’s Code Review feature highlights meaningful logic changes while downplaying formatting churn and moved blocks. This means your reviewers spend time on what matters rather than scrolling through mechanical edits.

GitKraken also introduces Code Suggest, which lets you propose actual code edits across any file in your project. Your teammates can apply changes with one click. Cloud Patches take collaboration even earlier by letting you share work-in-progress before opening a formal PR.

For teams managing multiple repositories, GitKraken Workspaces and Launchpad give you a centralized view of PRs, issues, and build status across GitHub, GitLab, Bitbucket, and Azure DevOps. You can pull, fetch, and clone across repos in a single action.

GitKraken features

• Code Review with Powerful Diff Viewer: Surfaces high-impact logic changes and visually distinguishes moved code from deleted-and-re-added code, reducing review noise
• Code Suggest: Propose real code edits across any file in a project, not just in the diff, giving reviewers the ability to fix issues directly
• Cloud Patches: Share work-in-progress code with teammates before committing to the repo, enabling early feedback loops that speed up merge times
• Launchpad: A unified dashboard that tracks PRs, issues, and build status across all connected repos so you can prioritize the right work
• Workspaces: Group and sync repositories from multiple providers, onboard developers with one-click cloning, and run multi-repo actions simultaneously

How does AI change the code review process for development teams?

AI is shifting code review from a fully manual process to an assisted one. AI-powered tools can summarize changes, flag potential bugs, and reduce the volume of noise reviewers need to wade through.

According to a 2025 empirical study from Chalmers University of Technology, developers generally prefer AI-led review summaries for large or unfamiliar pull requests, while maintaining human control over final approval decisions.

The key distinction is between AI that replaces human judgment and AI that supports it. GitKraken AI takes the human-first approach: AI surfaces context, generates summaries, and highlights risk areas, but developers remain in control of approval decisions.

This matters because code review is not just a quality gate. It is a knowledge-sharing mechanism. When AI handles the routine checks, your team can focus review conversations on architecture decisions, edge cases, and mentoring junior developers.

What should you prioritize when evaluating code review collaboration tools?

Start with how well the tool fits into your existing Git workflow. A platform that requires your team to leave their IDE or terminal to conduct reviews slows your team down rather than speeding it up.

Look for tools that support early collaboration, not just end-of-cycle review. Cloud Patches and work-in-progress sharing let you get feedback before a PR grows too large to review effectively.

Finally, consider multi-repo visibility. If your team works across multiple repositories, you need a single view where you can track review status, assign reviewers, and monitor build results. GitKraken Launchpad delivers this across GitHub, GitLab, Bitbucket, and Azure DevOps.

Why GitKraken is the best code review platform for development teams

Other code review platforms solve one piece of the puzzle. They either track metrics, automate PR routing, or analyze code health. GitKraken connects the entire review workflow from early collaboration through merge.

Code Suggest lets your reviewers propose real edits instead of writing comments that create follow-up work. Cloud Patches move feedback earlier in the development cycle, so PRs arrive already refined. And Launchpad gives you visibility across every repo your team touches.

GitKraken is built for team velocity and collaboration, with enterprise-grade security and privacy controls that scale with your organization. Over 100,000 organizations trust the platform to keep their development workflows productive and secure.
