## What it is
A lightweight cross-platform profiler library for C++ that instruments arbitrary code blocks with extremely low overhead (~15ns per block). It streams profiling data over the network or dumps it to file, and includes a GUI viewer with timeline rendering, statistics, and thread context-switch capture.

## Use cases
- profile function execution times in a C++ application
- find performance bottlenecks in game engine code
- measure how long specific blocks of code take
- capture thread context-switch events to analyze scheduling
- leave a profiler in release builds and enable it at runtime
- visualize profiling data on a timeline with a GUI

## When to choose
- you need a C/C++ profiler with minimal runtime overhead
- you want to instrument arbitrary code blocks with simple macros
- you need cross-platform profiling including Windows, Linux, macOS, and Android
- you want runtime-enabled profiling in production builds

## When to avoid
- you need GPU or hardware-level profiling
- you want a sampling profiler without code instrumentation
- your project is not in C/C++
- you need heap/memory profiling rather than time profiling

## Facets
- artifact type: library
- maturity: stable
- function: monitoring, benchmarking, developer-tools
- domain: performance, developer-tools, cross-platform
- platform: windows, cpp, cross-platform
- tags: profiler, instrumentation, low-overhead, timeline-gui, context-switch-capture, linux, macos, android
