AGNA: Applied Graph and Network Analysis Open Source

Applied Graph and Network Analysis Open Source is a desktop application for social network analysis, sociometry, and sequential analysis. It is designed for researchers, teachers, and students who want to create, visualize, and analyze networks without programming.

AGNA is particularly suited to small and medium research networks: communication, collaboration, affiliation, interaction, behavioral, institutional, historical, and other relational data. It can be used in sociology, anthropology, communication research, psychology, education, organizational research, animal-behavior studies, and the humanities.

AGNA 2.2.1 is the current stable open-source release. It introduces interactive random graph generation across 8 classical theoretical SNA models (Erdős–Rényi, Watts–Strogatz, Barabási–Albert, random connected graphs, and degree-preserving permutations), scalable node addition, default Bavelas-Leavitt centrality, and critical fixes for sociomatrix symmetrization, betweenness centrality, and table export dialogs, alongside standalone native GraalVM AOT CLI binaries (~7ms execution, zero Java dependency) and native Model Context Protocol (MCP) server support for AI agents.

AGNA Desktop, AGNA Core, and AGNA CLI are free and open-source software released under the Apache License, Version 2.0. The licence permits use, modification, distribution, and commercial use, subject to preservation of applicable copyright, licence, and notice material. It also includes an explicit patent licence.

The projects share a common architecture: AGNA Desktop provides the graphical interface; AGNA Core provides the reusable engine; and AGNA CLI makes core functions available for command-line, scripted, and reproducible work.
