In their own words
Joern
Joern analyzes source code, bytecode and binary code for vulnerability discovery and static program analysis research. It converts programs into code property graphs, providing a common structure for cross-language analysis. Users query those graphs with a strongly typed, extensible Scala-based domain-specific language. Features include parsing, taint analysis, search queries and passes that extend the graph representation. Joern Scan runs predefined queries and reports matching issues with their locations; queries can be selected by tag or name, and community contributions are accepted in the default database. Queries can be wrapped into custom scanners for CI. Joern also works as a library or through REST and HTTP APIs, including a server for graph construction and querying. Documented frontends cover C, C++, C#, Go, Java, JavaScript, Kotlin, PHP, Python, Ruby, Swift, x86/x64 and JVM bytecode, with varying maturity. Distributions target Linux, macOS and Windows on x86_64 and ARM64. Joern is free, Apache-2.0 licensed and requires JDK 21.
