It acts as a bridge between profiling tools and graph visualization, letting you generate call graphs and flame-graph-like diagrams from raw profiler data.\n\nThe tool supports filtering (pruning nodes and edges below thresholds), coloring by hot-spots, function name stripping, and graph comparison for before-and-after performance analysis. It runs on any platform with Python and Graphviz installed, making it a portable way to turn profiler output into publication-ready diagrams. No runtime Python dependencies are required.","worth_installing":"Yes. gprof2dot is a mature, well-established tool (first released 2009, active maintenance, 3454 GitHub stars) with zero known vulnerabilities, no runtime dependencies, and low install friction. The LGPL license is permissive for most use cases. Install it if you regularly work with profiler output and need to visualize call graphs; the only real prerequisite is having Graphviz installed separately on your system."},"id":"gprof2dot","links":{"html":"https://skillfed.io/packages/gprof2dot","md":"https://skillfed.io/packages/gprof2dot.md","pypi":"https://pypi.org/project/gprof2dot/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-04-14","license_spdx":null,"license_treatment":"copyleft","name":"gprof2dot","python_support":"supports_current","summary":"Generate a dot graph from the output of several profilers."},"popularity":{"monthly_downloads":6240383,"position":1950,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"2025.4.14"}
