-description: Open-source code analysis platform for C/C++ based on code property graphs
+description: >-
+  Joern is a platform for analyzing source code, bytecode, and binary executables.
+  It generates code property graphs (CPGs), a graph representation of code for cross-language code analysis.
+  Code property graphs are stored in a custom graph database.
+  This allows code to be mined using search queries formulated in a Scala-based domain-specific query language.
+  Joern is developed with the goal of providing a useful tool for vulnerability discovery and research in static program analysis.
