## What it is
Heaptrack is a heap memory profiler for Linux that traces every memory allocation and annotates it with a stack trace. It ships with command-line and GUI analysis tools that interpret the recorded profile to reveal memory leaks, allocation hotspots, and temporary allocations.

## Use cases
- find memory leaks in a C++ application
- profile heap memory allocations on linux
- reduce my application's memory footprint
- find which code locations allocate the most memory
- detect excessive temporary allocations that churn the heap
- attach a memory profiler to an already running process
- record memory traces on an embedded linux device and analyze them later

## When to choose
- You need heap-level allocation tracing with stack traces for native Linux applications
- You are hunting memory leaks, allocation hotspots, or temporary allocations in C/C++ code
- You profile embedded targets without debug symbols and want to interpret traces later against a sysroot

## When to avoid
- You need CPU, GPU, or I/O profiling rather than heap memory analysis
- You develop on Windows or macOS, since heaptrack is Linux-only
- You need to profile managed runtimes like the JVM or JavaScript rather than native allocations
