Mutineer vs pymute
Both stand on mutation testing tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan
Mutineer offers mutation testing with targeted runs, multiple report formats and support for the listed JavaScript and TypeScript frameworks. Its Node.js requirement and the potential duration of full-codebase runs are worth considering.

pymute provides configurable mutation testing for Python with pytest or tox, plus parallel execution and surviving-mutant reports. Before adopting it, account for the Rust and Cargo requirement, the pytest project layout constraint, and the disk space used by parallel threads.
