Best Code Review Tools Which Ranked and Reviewed in 2022

No-code platforms have grown in popularity among people who don’t want to spend time learning how to code in recent years. This enables them to avoid creating code while yet obtaining the necessary capabilities.

For instance, a lot of web design tools let users build websites without having to know HTML. The best project management software includes no-code platforms that can help save time and money while guaranteeing that a project is finished on schedule.

Despite this, it is still essential in the realm of development to understand how code functions, what functionality it offers, and how to effectively optimise it.

Code review tools are crucial for these developers.

Code review is a vital stage in any software development cycle when engineers test the source code to find issues as soon as possible. Code reviews are often carried out by teams prior to merging. When done correctly, the code review reduces defects and errors, boosts the code’s quality, and aids the team in achieving its objectives.

What Are The Best Code Review Tools?

The top code review tools for developers to think about are listed below.

1. Review Board

Review Board is a great code review tool that is web-based and open-source that you may test out before installing using the website’s demo. If you want to utilise and run Review Board, you’ll need Python, a MySQL or PostgreSQL database, and a webserver.

One of Review Board’s biggest advantages is its integration with the most well-liked version control programmes, such as CVS, Git, and Subversion. You may store screenshots for documentation without leaving the tool thanks to interfaces with programmes like Amazon S3.

In addition to code evaluations, Review Board also performs document reviews.

Review Board Features :

  • To increase the quality of your code and ensure that it complies with coding standards, review, discuss, and keep track of the issues that need to be corrected.
  • You may access all review requests that are important to you in one location.
  • A fantastic technique to raise the calibre of the code produced by your team is to use Review Bot to automatically review code.
  • Additionally, Review Board offers command-line tools that make it simple to connect to every repository you have and begin conducting code reviews.

Pricing :

The Review Board has not given a price for this good or service. For software vendors and service providers, this is standard procedure. To get the most recent prices, speak with Review Board.

The software vendor provides Review Board with pricing information, or it can be found in pricing papers that are available to the general public. The vendor must be negotiated with over the purchase price of the Review Board.


Market evangelists contend that competition fosters innovation. In the case of GitLab, that is unquestionably the situation. Notably, the GitHub rival provides free private repositories that are open to an infinite number of participants. Though free access there is restricted to three collaborators, it appears that this prompted GitHub to match the offer.

According to Ali Karbassi, CEO of the educational group We All Code, “people were emigrating because you don’t want to make all your code open source.” That slightly pushed GitHub’s model.

However, GitLab continues to be a desirable solution in part due of its lack of a collaborator cap. GitLab may be preferred by some businesses over GitHub for code review, not due to security issues, according to Ghosh, but rather because it allows customers more control over who may access what.

For instance, reviewers can visit GitLab without needing source code permission.

On the other hand, several developers have criticised GitLab for a variety of UX/UI issues. These issues aren’t serious, but there is space for development. In the past, GitLab was forced to make significant usability enhancements due to frequent complaints about the information architecture and contrast.

They are working hard, but there is room for improvement in terms of usability and design, according to Karbassi. It’s simply a little bit more difficult to understand at first.

GitLab has reportedly taken note of the complaints and has created a strong UX strategy to enhance the usability of the website.

GITLAB Pricing

GitLab has 6 editions with prices ranging from $0 to $99. GitLab also offers a risk-free trial. To determine which edition is best for you, look at the many pricing options below and read more details about the product here.

3. Visual Expert

For thorough code reviews in Oracle, SQL Server, and PowerBuilder, turn to Visual Expert.

The Visual Expert toolkit includes CRUD matrix generation, automatic code description, E/R diagrams synchronised with code, code performance analysis, and many more features.

Visual Expert Key Features

Examples of components Visual Expert can list that are not mentioned in your code are objects, functions, variables, tables, and columns.

Visual Expert can be used to compute the total amount of Source Lines of Code (SLOC), as well as the number of objects, functions, and variables.

Any potential problems in your code should be found and fixed.

Visual Expert Pricing

Packages start at $495 per year.

4. ESLint

a pluggable and customizable linter tool for JavaScript that can find patterns and report them. Maintain the quality of your code with simplicity.

A tech stack’s Code Review category includes the tool ESLint.
A utility called ESLint is open source and has 20.8K stars and 3.7K GitHub forks. Here is a link to the GitHub repository for ESLint’s open source code.

1801 companies reportedly use ESLint in their tech stacks, including Udemy, CRED, and KAVAK.

ESlint Features

  • Consistent JavaScript: Opinions are no longer relevant
  • Integration of IDE
  • Free
  • Customizable
  • Examines code quality rather than style
  • large user base and support ecosystem

Customer Experience :

Because we prefer to reduce general thought-overhead when designing software, we use ESLint. ESLint gives customers a tonne of customization options in addition to a tonne of presets. In addition to the javascript “normal” configuration, we employ ESLint (and for our vueJS-projects the “recommended” settings).

JSHint was the second alternative we thought about, but we abandoned it because ESLint is being developed more quickly and natively supports ESnext, which is crucial for us.

5. Azure DevOps.

Things to Take into Account When Selecting a Code Review Tool

Capture Method

The following examples of internal process measurements are always a good idea:

  • The inspection rate is the speed at which reviews are finished.
  • The defect rate is the number of faults found per hour of evaluation.
  • Defect density is the average number of defects found per line of code.

In reality, only automated or well controlled procedures can result in repeatable metrics. A metrics-focused code review tool will automatically collect data, guaranteeing that it is accurate and devoid of human bias.


For faults to be fixed, effective teamwork is necessary.

The easiest way to make sure that problems are fixed is to use a collaborative code review platform that enables reviewers to log errors, discuss them with the author, and approve adjustments in the code. Without the use of an automated tool, defects found during review are unlikely to be reported in the team’s standard defect tracking system because they are found before code is handed to QA.

When Would It Be Appropriate to Use Code Review Tools?

Automated code review tools have been around for a long, just like static analysis and unit testing frameworks. Code review must be automated nonetheless because of the need for speed and agility in order to meet business objectives. As a result, there will be 10 times less time wasted and more accurate outcomes.

Code review tools are the way to go if you want to find issues quickly and fix them even more quickly.

How Can Code Review Help to Cut Down on Errors?

When you are working with a limited budget and amount of time, it is quite simple to make mistakes in your code. Even the best programmers can get cross-eyed by staring at their own code for too long, despite your confidence in your work. Code review can help you find flaws and simple coding problems before your product advances to the next stage, improving the efficiency of the software delivery process.

How Does Code Review Enhance the Performance of the Code?

Because they lack experience, some younger developers might not be aware of optimization techniques that could be used to their code. The code review procedure enables these programmers to develop new skills while also enhancing the functionality of their code.

Many programmers seek to implement the most important functions in compact, performance-efficient code. But doing so will make the code more complex and make it harder to read. (Note that a code’s compactness does not automatically translate into an easy-to-understand logic.) In subsequent stages of development, the data model upon which the code is based may also change. Because of this early optimization, maintenance expenses will eventually increase.
