About uniprof.sh
uniprof.sh is a lightweight, terminal-based CPU profiling utility for macOS that lets developers quickly sample and inspect the performance of any running process. It leverages macOS's built-in sample command under the hood and presents results in a clean, readable format directly in your shell. The tool is designed for developers who want fast, no-frills profiling without leaving the command line.
- Process Sampling: Run uniprof.sh with a process name or PID to capture a CPU sample and display a flame-graph-style call tree in the terminal.
- macOS Native Integration: Built on top of macOS's native
sampleutility, ensuring accurate and low-overhead profiling without additional dependencies. - Terminal-Friendly Output: Results are formatted for readability in the terminal, making it easy to spot hot code paths at a glance.
- Minimal Setup: Install via a single shell script — no package manager or build step required; just download and run.
- Open Source: The project is open source and hosted on GitHub, welcoming contributions and community improvements.
