DeepCode
DeepCode is an AI-powered code review and static application security testing technology that combines symbolic and generative AI with machine learning trained on large volumes of permissively licensed open-source code. A security knowledge base maintained by Snyk researchers backs it, and together they surface bugs, security vulnerabilities, and code quality issues.
Snyk now brands the engine DeepCode AI, and it powers Snyk Code, the static analysis product in the Snyk AI Security Platform.
DeepCode scans code changes in real time, leaving review comments on pull requests and highlighting issues directly inside integrated development environments (IDEs), such as JetBrains IDEs and Visual Studio Code. The same engine also drives Snyk Agent Fix, formerly known as DeepCode AI Fix.
Since May 2026, Agent Fix has used an agentic architecture that pairs the static analysis engine with large language models. It prompts them with Snyk’s database of more than 35,000 expert-written fixes and automatically retries any candidate fix that fails a re-scan. Its one-click remediations now cover every language Snyk Code supports.
DeepCode AI also prioritizes the issues it finds by risk. Its semantic models go beyond simple pattern matching to understand program logic, data flow, and API usage across files.
