Static code analysis by Qodana helps development teams follow agreed quality standards, and deliver readable, maintainable, and secure code. Powered by JetBrains. We’ve been perfecting the code analysis in our IDEs for 20+ years based on feedback from millions of community members. Qodana relies on the lines of JetBrains IDEs and brings their intelligence to the CI side. Just like in our IDEs, Qodana’s analysis is accurate but not overbearing and understands the nuances of your code. Integration with tools developers use daily, including JetBrains IDEs, makes it easy to work with Qodana’s results in whichever tool you're most comfortable with. Qodana doesn’t only report problems; it also suggests automatic fixes. Qodana calculates licenses per active contributor, so it won’t cause unexpected expenses or charge you for growing your project (as we don’t calculate LOCs). It’s also free for open-source projects.

The Code Registry is an AI-powered code intelligence and analysis platform that gives businesses and non-technical stakeholders full visibility into their software codebase, even if they don’t write code themselves. Upon connecting your code repository (GitHub, GitLab, Bitbucket, Azure DevOps, or uploading a zipped archive), the platform creates a secure “IP Vault” and runs a comprehensive automated analysis across your entire codebase. It produces a range of reports and dashboards, including a code-complexity score (revealing how intricate or maintainable your code is), open-source component analysis (detecting dependencies, license status, outdated or vulnerable libraries), security analysis (identifying potential vulnerabilities, insecure configurations or risky dependencies), and a “cost-to-replicate” valuation, estimating how much effort or resources it would take to rebuild or replace the software from scratch.
