What hackers pick instead
- perfFree Linux profiler that people rely on to find where code spends its time, and to build intuition for CPU performance. Its output is raw, and it expects you to already understand the OS.13recommend
- Java Flight RecorderPeople recommend it as a free, low-overhead profiler and telemetry tool for diagnosing Java performance and memory problems, including in production. No critic in these quotes names a caveat.10recommend
- InstrumentsApple's free performance profiler bundled with Xcode, praised for finding bottlenecks and for its UI; critics note its trace format is proprietary.9recommend
- PerfettoFree tool that spares you building your own trace viewer. Critics say it is less seamless than chrome://tracing.8recommend
- Python 3.15 sampling profilerBuilt into Python 3.15, it gives sampling profiling with strong reporting and a live mode. Critics note it cannot be switched on and off from code.6recommend
