About Sonar

Sonar helps prevent code quality and code security issues from reaching production, amplifies developers’ productivity in concert with AI assistants, and improves the developer experience with streamlined workflows. Sonar analyzes all code, regardless of who writes it—your internal team, genAI, or third parties—resulting in more secure, reliable, and maintainable applications. Rooted in the open source community, Sonar’s solutions support over 30 programming languages, frameworks, and infrastructure technologies.

Today, Sonar is used by +7M developers and 400K organizations worldwide, including the DoD, Microsoft, NASA, Master Card, Siemens, and T‑Mobile.

At Sonar, we’re a group of brilliant, motivated, and driven professionals working hard to help supercharge developers to build better, faster. Our solutions don’t just solve symptoms of problems—we fix issues at the source for all code, whether it’s developer‑written, AI‑generated, or from third parties.
