Sourcetrail

Sourcetrail is a tool that helps software developers to understand and navigate source code. Like a street map it draws your source code and helps to see connections and maintain an overview.
Using a combination of an interactive code graph, a powerful search function and a complementary code view it shows you your code from a new perspective. Sourcetrail works on Windows, Linux and macOS and can communicate with existing source editors/IDEs to integrate into your workflow.
