benefits of Clean Code

cleaner code. lower maintenance.

Clean code is easier to read, reuse, and enhance, keeping maintenance time and costs to a minimum. Create well-organized scalable, reliable, testable software that improves code quality.

keep your developers. happy.

By keeping the most essential piece of your workplace—your code—clean, you create an enjoyable and satisfactory work environment for everyone. Code that's modular, easy to understand, and modify helps improve developer collaboration. 

rework less. innovate more.

Generate greater business value by empowering developers to focus on solving interesting problems instead of spending time on remediating old problems. Clean code improves software quality, increases productivity, so you can deliver more features. 

minimize risks. maximize reputation.

Sonar keeps your software robust and secure with the right checks at the right place and time. Limit the risk of introducing security vulnerabilities during the agile development process with code reviews. 

A must-have for developers

there's a new standard for source code.

Our unique approach

clean code throughout the development workflow

Clean as You Code  -->
When coding

discover issues from the moment you write code

The best place to find and fix issues? Right in your IDE, with on-the-fly optimized feedback on bugs, security issues, code smells, and other problems.

Issues with code are revealed within the developers platform while guidance for remediation is provided from Sonar
When pushing

automated code analysis made easy

Augment manual code reviews with automated code analysis results available on Pull Requests right when it's needed.

The results of a pull request are shared
When Promoting

production-ready applications every time

Intelligent promotion of clean builds. Find out if an application passes or fails the release criteria with a Quality Gate—an out-of-the-box feature that natively implements the Clean as You Code™ practice.

New code is represented as a rocket taking off after having passed the organization's quality gate.
When Managing

assess risk throughout the whole organization

Gain visibility on operational, reputational, and security risks across the entire application portfolio with governance features designed for management teams.

A reliability rating of C and a score of 41.3% for coverage of new code is shown, giving an example of quality scores for a project.
