Code Quality & Code Security made simple.

Detect, understand, and fix issues in your code, at the very earliest in your workflow.

Detect Bugs and Vulnerabilities

Bug, Vulnerability, and Code Smell detection

Get rid of issues that represent a risk for your reputation or add up to your technical debt. Keep Security Hotspots (potential threats that need a human review) on the radar.

Issue contextualization with clear remediation guidance

Issue contextualization, with remediation guidance

Find, understand, and fix code issues thanks to our helpful UI that shows the issues in the context of the code, with clear remediation guidance.

Top-notch coding rules

Top-notch coding rules

Get a deep understanding of why an issue has been raised from the underlying rule, including a full description along with an example of proper implementation.

Pull Request analysis

Continous inspection

Check code Maintainability, Reliability, and Security in your development branches AND pull requests. Shift left by dealing with issues sooner in your workflow.

GitHub Pull Request

In-ALM pull request feedback

Receive instant feedback on your PR in the ALM directly. SonarCloud sends a report of the analysis in the PR thread so you don’t have to switch context when your code is fine.

Quality Gate

Go/No Go Quality Gate

Fail pipelines when the quality or security of your code doesn’t meet the requirements you set for it. Don't let issues make their way to production.

Issue collaboration

Team onboarding

Share coding best practices and have fun writing code together. Collaborate on fixing an issue: leave a comment, set a status, or assign it to a team member.
