nXSrc

nXSrc is an open-source software framework designed to support cross-language source code analysis, search, and transformation. It aims to help developers navigate large codebases by unifying indexing, AST representations, and tooling across languages.

The architecture centers on a modular core and language-specific adapters. It offers an indexing engine that builds language-agnostic representations, a query language for finding code patterns, and a set of transformation pipelines for refactoring and code modernization. It provides both command-line interfaces and a web-based explorer.

nXSrc uses a plugin-based model where new languages are added via adapters. It supports incremental indexing, caching, and distributed processing to handle large repositories. The data model includes a shared intermediate representation for code facts.

Since its release, nXSrc has been adopted by research groups and software teams for code comprehension, quality assurance, and maintenance workflows. Development is community-driven with governance by contributor guidelines and a code of conduct.

nXSrc is distributed under an open-source license and is available on its official repository. Documentation covers installation, architecture, language adapters, and extension development.
