The State of Python Profiling in 2026
Summary
The State of Python Profiling in 2026 surveys CPython's built-in sampling profiler Tachyon and compares major external profilers like py-spy, Scalene, and Austin. It explains tracing versus sampling, in-process versus out-of-process approaches, and discusses asyncio support and native profiling. It also notes increasing accessibility through tooling and agent-assisted workflows.
