| Fact | c8 | Coverage.py |
|---|---|---|
| Configuration | c8 accepts command-line flags, a c8 section in package.json, or a JSON configuration file. | Settings can live in .coveragerc, TOML, setup.cfg, tox.ini, or pyproject.toml files. |
| Installation | The README shows installing c8 globally with npm and running it with a Node.js script. | The documented installation command is `python3 -m pip install coverage`. |
| License | The repository identifies its license as ISC. | Coverage.py is licensed under the Apache 2.0 License. |
| Purpose | c8 produces code coverage reports using Node.js’ built-in V8 coverage. | Coverage.py measures which parts of Python programs ran and identifies executable code that did not run, commonly to gauge test effectiveness. |
| Report formats | The README documents Istanbul-compatible reporters and an experimental Monocart option with v8 and console-details reporters. | Reports can be emitted as text, HTML, XML, LCOV, or JSON. |
| Security | The repository has a Security and quality section, but the opened security page did not expose specific security or compliance claims. | The project directs vulnerability reports to Tidelift, which it says will coordinate the fix and disclosure. |

Pick c8 if…
c8 suits JavaScript, TypeScript, and JSX developers who want command-line coverage reports and configurable coverage gates. It is relevant when source-map remapping or Istanbul-compatible reporting is useful.
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.
