Austin TUI is a top-like text-based user interface for Austin, the frame stack sampler for CPython.
This is free and open source software.
Features include:
- Thread navigation – profiling data is processed on a per-thread basis. The total number of threads (across all processes, if sampling child processes) is displayed in the top-right corner of the TUI.
- Full mode – shows you statistics of the last seen stack for each process and thread when the UI is refreshed (about every second).
- Graph mode – live flame graph visualisation of the current thread statistics.
- Save statistics.
- Threshold – reduce the amount of data that’s displayed.
- Cross-platform support – runs under Linux, macOS, and Windows.
