Austin is a frame stack sampler for CPython written in C, used to profile running Python processes without instrumentation. It samples stack frames and outputs data suitable for generating flame graphs and other performance visualizations.
Use cases
- profile a running Python application without modifying its code
- find CPU hotspots in Python programs
- generate flame graphs from Python stack samples
- profile production Python processes with low overhead
- debug performance issues in multi-threaded Python code
When to choose
- you need a low-overhead sampling profiler for CPython
- you want to profile processes without code instrumentation
- you need cross-platform Python profiling on Linux, macOS, or Windows
When to avoid
- you need line-level or memory profiling rather than frame stack sampling
- you want a pure-Python profiler that requires no native binary
