| Installation | The documented installation command is `python3 -m pip install coverage`. | The README shows installation as a per-project dependency with Composer. |
| License | Coverage.py is licensed under the Apache 2.0 License. | The repository identifies the library's license as BSD-3-Clause. |
| Purpose | Coverage.py measures which parts of Python programs ran and identifies executable code that did not run, commonly to gauge test effectiveness. | The library collects, processes, and renders PHP code coverage information. |
| Report formats | Reports can be emitted as text, HTML, XML, LCOV, or JSON. | The PHPUnit manual lists HTML, Clover, OpenClover, Cobertura, Crap4J, PHPUnit XML, text, JSONL and serialized PHP output. |
| Security reporting | PyPI directs vulnerability reports to Tidelift, which coordinates fixes and disclosure. | The security policy asks vulnerability reporters to use coordinated disclosure and says not to report vulnerabilities through public GitHub issues, discussions, or pull requests. |

In their own words
Coverage.py
Coverage.py measures which parts of Python programs run and highlights executable code that remains untouched, helping developers assess what their tests exercise. It measures statement coverage by default and can also track branch coverage. Reports are available as text, HTML, XML, LCOV, and JSON. Dynamic contexts can associate lines of execution with the test function that ran them. Coverage.py can run test suites through their usual command; pytest-cov is available but the documentation says most users do not need it. Third-party plugins can extend measurement to non-Python files, such as connecting executed Python to Django templates. Data is stored in a SQLite database, and advanced use can rely on its API. The current documentation lists Python 3.10 through 3.15 rc2 and PyPy3 versions 3.10 and 3.11. The tool provides ctrace, pytrace, and sysmon measurement cores; sysmon is faster for simple line and branch coverage but lacks support for dynamic contexts and plugins. Coverage.py is licensed under Apache 2.0 and runs on Linux, macOS, and Windows, with self-hosting available. It is free.
