Key Features:

Generates interactive, zoomable flame graphs from V8 profiles
Blazing fast processing and rendering of performance data
Supports output from Node.js --prof and --cpu-prof flags
Provides a web-based interface for detailed analysis
Open-source and designed for easy integration into workflows

Use Cases:

Profiling and optimizing Node.js application performance
Identifying CPU-intensive functions and bottlenecks in code
Visualizing call stack data for debugging performance issues

Alternatives:

speedscope – Another flame graph viewer; Flamebearer is often noted for its speed and specific optimization for V8/Node profiles.
flamegraph.pl – The original Perl-based flame graph generator; Flamebearer is a modern, web-focused alternative for the JavaScript ecosystem.
