## What it is
Node.js native bindings (C++) to the V8 profiler, exposing CPU profiling and heap snapshot APIs programmatically. It integrates with node-inspector for debugging and performance analysis of Node applications.

## Use cases
- profile cpu usage of a node.js application
- take heap snapshots to find memory leaks
- compare two heap snapshots to detect memory growth
- export v8 cpu profiles for analysis in devtools
- adjust cpu profiler sampling interval
- integrate profiling into node-inspector

## When to choose
- you need programmatic CPU or heap profiling in Node.js
- you are maintaining legacy code already using v8-profiler or node-inspector

## When to avoid
- starting a new project - use the built-in inspector module or modern profilers
- you need actively maintained software with recent updates
- you need profiling for non-V8 runtimes

## Facets
- artifact type: library
- maturity: abandoned
- function: monitoring, benchmarking, developer-tools
- domain: performance, developer-tools, backend
- platform: cross-platform
- tags: v8, cpu-profiling, heap-snapshots, native-addons, profiling, nodejs
