Best 6 Code Review Tools in 2026: Find Your Best Fit

Introduction

Graphite is the strongest overall pick in this group of code review tools. It combines AI pull request reviews with stacked pull requests and a merge queue. This roundup compares six options for teams that want to review changes, understand their impact, or improve code quality.

Quick comparison

Choose Graphite for workflow management, Graphide for context on a change’s impact, or Codacy to bring analyzers together. For the other tools, compare their review features with your team’s needs. Check current integrations and pricing before you adopt one.

1. Graphite

Best for: Teams that want AI reviews alongside a structured pull request workflow.

Graphite combines pull request reviews with stacked pull requests and a merge queue, and syncs with GitHub. Its main draw is the workflow support. Stacking helps teams organize related pull requests, while the merge queue manages changes on their way to a merge. Graphite is a good fit for teams that want review assistance and a clearer path from open pull request to merge. Check current feature availability and pricing before you choose it.

2. Graphide

Best for: Developers who need to see which parts of a codebase a change may affect.

Graphide’s GitHub App reviews pull requests and highlights affected areas of the codebase. That change-impact context can help reviewers see where a proposed change might have consequences, beyond the lines that were edited. It’s worth considering if reviewers need help getting oriented in a codebase. Check the current GitHub workflow and feature availability to see whether it fits your team.

3. Squire

Best for: Teams seeking code review and help preparing pull requests.

Squire describes itself as an agentic code review and quality platform. It reviews code and writes pull request descriptions, covering both the changes themselves and the explanation that goes with them. Automatic pull request descriptions are a notable feature, especially for teams that want review support and help documenting changes. The available details don’t specify platform integrations or pricing, so check those before comparing Squire with other tools.

4. Baz

Best for: Teams looking for an AI-focused code review platform.

Baz is described as a platform for reviewing code with AI. That makes AI review its defining feature, but the available information doesn’t specify integrations, pricing, or how it fits into a particular pull request workflow. If you’re evaluating Baz, check those details directly and compare its review capabilities with your existing process. Its focused description may suit teams looking primarily for an AI review tool.

5. CodeRabbit

Best for: Teams that want automated feedback on pull request changes.

CodeRabbit is an AI pull request reviewer that provides automated feedback on code changes during the pull request process. The feedback comes within the review workflow, so teams can assess proposed changes as they review them. The available information doesn’t specify pricing or integrations. Before adopting it, confirm that it works with your repository platform and check which features each plan includes.

6. Codacy

Best for: Teams that want code quality and security checks alongside pull request review.

Codacy is a code quality and security platform that brings code analyzers together and includes pull request review capabilities. Its analyzer aggregation lets teams include code analysis in a broader quality and security setup, rather than focusing only on review comments. Consider Codacy if code checks matter alongside reviewing changes. Check which analyzers, integrations, and features are currently available for your repositories.

How we picked these tools

This roundup covers tools with a clear role in code review, pull request workflows, or related code quality checks. We compared each product based on its stated capabilities, not unsupported claims about performance, pricing, or customer results.

The tools vary in scope. Some focus on code review; others also offer change-impact context, pull request workflow management, quality checks, or security features. Knowing the difference can help you narrow the list to the problem you need to solve.

Frequently asked questions

What do code review tools do?

Code review tools help teams examine proposed code changes, often as part of a pull request workflow. Depending on the product, they may provide automated feedback, show a change’s impact, or help manage review and merge steps.

How does AI review differ from analyzer checks?

AI review tools use AI to provide feedback on changes. Analyzer-based checks use code analysis tools to identify quality or security issues, and some platforms bring multiple analyzers together. The two approaches can complement each other, but they aren’t the same.

What should a GitHub team check?

Confirm that a tool supports your GitHub workflow and the features your team needs, such as pull request reviews or merge management. Check current pricing, integrations, and feature availability before adopting it.

The verdict

Based on the available information, Graphite is the strongest overall pick. It combines AI pull request reviews with stacked pull requests and a merge queue. Graphide is a good alternative for teams that want to see which code areas a change may affect. Codacy suits teams looking for analyzer aggregation and code quality or security features alongside pull request review.
