Unlike runtime profilers, it performs static analysis by examining code structure rather than executing it, making it useful for understanding architecture without running the code. The tool outputs graphs in multiple formats\u2014GraphViz DOT, yEd, SVG, HTML, or plain text\u2014and supports filtering by depth, direction, and import cycles. It also performs module-level dependency analysis to detect circular imports.\n\nThe package was recently revived in February 2026 with support for modern Python syntax (walrus operators, match statements, async with, type aliases) across Python 3.10\u20133.14. It includes a comprehensive test suite and offers both a command-line interface and a Python API for programmatic use. The single runtime dependency is jinja2, keeping the install footprint minimal.","worth_installing":"Yes, if you need static call-graph visualization or dependency analysis. The package is actively maintained, supports current Python versions, has low install friction, and offers both CLI and API modes. The copyleft GPL-2.0-or-later license is a consideration only if you plan to redistribute derivative code commercially. No known vulnerabilities."},"id":"pyan3","links":{"html":"https://skillfed.io/packages/pyan3","md":"https://skillfed.io/packages/pyan3.md","pypi":"https://pypi.org/project/pyan3/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-14","license_spdx":"GPL-2.0-or-later","license_treatment":"copyleft","name":"pyan3","python_support":"supports_current","summary":"Generate approximate call graphs for Python programs"},"popularity":{"monthly_downloads":204166,"position":9615,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.6.2"}
