The original open-source FlameGraph tools by Brendan Gregg, a set of Perl scripts that convert profiler stack traces into interactive SVG flame graph visualizations. It works with profilers like Linux perf_events, DTrace, SystemTap, and pmcstat via stackcollapse converters.
Use cases
- visualize CPU profiling stack traces as flame graphs
- find the most frequent code paths in a profiled application
- generate interactive SVG flame graphs from perf script output
- profile memory and off-CPU time
- compare profiles with differential flame graphs
- fold captured stacks from various profilers into a common format
When to choose
- you need the canonical, widely-supported flame graph tooling
- you profile with perf, DTrace, SystemTap, or similar profilers and want interactive SVG output
- you want lightweight scripts with no dependencies that run anywhere Perl runs
When to avoid
- you want a modern GUI-based profiler with built-in visualization
- you need a single integrated tool that captures and visualizes profiles in one step
- you require a license for enterprise compliance (the repo has no explicit license)
