Sourcetrail is an interactive source code explorer and visualizer designed for indexing and navigating relationships between symbols and structures across large, multi-language codebases. It functions as a static analysis indexer and code dependency visualizer that maps calls and dependencies between source files to help reveal project architecture.
The tool enables multi-language project analysis by using a language-agnostic indexing system to track symbols across different programming languages within a single interface. It allows for the discovery of software architecture and the exploration of execution logic in complex projects through interactive visual maps and symbol searches.
The system provides capabilities for indexing source code, visualizing code structures, and mapping relationships between elements. It also includes a toolkit to extend language support through plugins.
