Code review is a crucial step to ensure product quality. But when it comes to choosing between a manual or automated code review, which one is the better option? Let’s dive into the pros and cons of each to help you decide what works best for your team and project.
Manual Code Review
In a manual code review, a developer checks the code written by someone else, looking at quality, performance, and whether everything follows team standards.
Pros of Manual Review
The big advantage of manual review is that it allows for a deeper analysis of things beyond rules and standards. Things like business logic, architecture decisions, and solutions to specific problems are areas where the human touch makes a difference. Plus, it’s a great opportunity for developers to share ideas and learn from each other, boosting team collaboration.
Another point is that manual review can identify issues that are more subjective and hard to automate. For example, you might notice that a function could be simpler or that a solution could be improved with a different approach. This helps ensure that the code is not only technically sound but also aligned with the project goals and team culture.
Cons of Manual Review
On the other hand, manual review can be time-consuming, and in high-demand teams, it often becomes a bottleneck. Reviewing large amounts of code manually can delay releases and reduce productivity.
Another challenge is subjectivity. Since each developer has their own style and opinions, the process can lead to unnecessary debates, which can also slow down the project.
Automated Code Review
Automated code review uses technology to streamline the code review process, eliminating repetitive tasks and spotting issues quickly and accurately. Instead of someone reviewing line by line manually, automated tools check the code, looking for everything from simple errors to more complex issues like style violations and potential security risks.
With the rise of AI, automated reviews have become even more advanced. Today, automated tools can learn from the code they review, understand the context of the project, and even adjust to the team’s standards, suggesting improvements that make sense for the team.
Automating code review brings several benefits, such as:
- Speed: Automated processes can review large volumes of code in a fraction of the time it would take for a manual review. This helps keep development moving fast without creating bottlenecks.
- Accuracy: AI can precisely identify issues like standard violations or excessive complexity consistently. Unlike human reviewers, AI doesn’t get tired or distracted, ensuring a constant level of quality in the analysis.
- Reducing Human Error: Manual code review can be subjective, leading to different interpretations and sometimes mistakes. Automation removes this subjectivity by applying rules and standards uniformly.
- Continuous Learning: With AI, the automated code review process gets better over time. Each review allows the AI to learn from developers’ corrections and adjust its future analyses, becoming more efficient.
- Focus on What Matters: By automating technical and repetitive checks like code style and minor bugs, developers can focus their energy on more complex and creative aspects of the code, like business logic and architecture.
- Consistency: AI ensures that the same rules and criteria are applied to all reviews, promoting a more standardized and consistent codebase, no matter who did the review.
Automating code review doesn’t replace human reviews but greatly helps speed up the process and makes reviews more efficient. This way, the team can focus on what really matters.
How Kodus does Code Review with AI
Kody doesn’t just catch common issues like syntax errors, formatting problems, and code standards—it also understands the context of the code. This means it can provide much more relevant suggestions, tailored to the project and team practices.
Another great feature is how well it integrates with the team’s workflow. Kody connects directly to the code repository, analyzing each pull request and offering automatic suggestions without disrupting developers’ rhythm. Plus, it’s flexible and can be configured to apply different rules and quality standards depending on the project’s context, ensuring each team gets an analysis aligned with their specific needs.
Kody also avoids the dreaded false positives that tend to frustrate developers with other automated tools. By using AI to understand code patterns and project history, it can filter out irrelevant issues and focus on what truly matters, boosting the efficiency of the review process.

Finding the right balance
So, what’s the best option: manual or automated review? It depends. Both have their pros and cons, and the key is to figure out what works best for your team and project.
No matter the approach, the important thing is that the code review process helps improve software quality and makes the team’s work easier. Combining the strengths of both approaches might be the key to ensuring an efficient workflow and well-reviewed code.
