A Rust-powered flamegraph generator and cargo subcommand built on the Inferno library, profiling arbitrary binaries without Perl or pipes. It supports Linux via perf, macOS via xctrace, and Windows natively through the blondie library.
Use cases
- generate flamegraphs for rust projects
- profile a binary and visualize hot paths
- find performance bottlenecks in my code
- cargo flamegraph subcommand for profiling
- create flamegraphs without perl or pipes
- profile applications on windows or macos
When to choose
- you want quick flamegraphs for Rust cargo projects
- you need cross-platform profiling on Linux, macOS, or Windows
- you want a single Rust binary instead of the Perl flamegraph stack
When to avoid
- you need an interactive profiler UI (consider samply or Firefox Profiler)
- you need sampling-based profiling beyond what perf/xctrace/dtrace provide
- you are on an unsupported platform or cannot install perf
