| Fact | Coverage.py | LLVM llvm-cov |
|---|---|---|
| Integrations | Official examples cover pytest, unittest, and nose, and pytest commonly uses the pytest-cov plugin. | The documentation describes using llvm-profdata to merge raw or indexed profiles and exporting coverage in lcov format. |
| Purpose | Coverage.py measures which parts of Python programs ran and identifies executable code that did not run, commonly to gauge test effectiveness. | llvm-cov shows code coverage information for programs instrumented to emit profile data. |
| Security | The project directs vulnerability reports to Tidelift, which it says will coordinate the fix and disclosure. | LLVM says its language frontends, analyzers, optimizers, and code generators are not hardened against malicious input, which can cause arbitrary code execution in LLVM. |

Pick Coverage.py if…
Coverage.py is for developers measuring how much of their Python code their tests exercise. Its report formats and dynamic contexts can help teams inspect coverage in different ways.
Pick LLVM llvm-cov if…
llvm-cov is for developers examining coverage from instrumented C, C++, Objective-C, or Objective-C++ programs. It may suit teams that need line-level details, summary metrics, or machine-readable coverage exports.
