| Purpose | ArcMutate extends PiTest to find bugs missed by tests through mutation testing for Java, Kotlin, and Android software. | Infection mutates PHP source code and reports changes that a test suite fails to catch. |
| Security | The maker says it has no sight of customer code, data stays within the customer's network, and the product can be used in fully air-gapped environments. | The maker says its PHAR distribution is signed with a GPG key and documents how to verify the signature and fingerprint. |

In their own words
Infection
Infection is a PHP mutation-testing library that shows which changes a test suite fails to detect. It creates mutants using predefined operators, runs tests against changed code, and records killed and escaped mutants, errors, and timeouts. Its Mutation Score Indicator measures the share of generated mutations detected by tests; it also reports Mutation Code Coverage and Covered Code Mutation Score Indicator. Infection supports PHPUnit, PhpSpec, Codeception, and Testo, and runs from the command line at a project root. Teams can run mutated tests in parallel, focus analysis on touched lines or files, and set minimum mutation-score thresholds that fail a build. The homepage describes more than 100 mutators grouped into profiles and allows custom mutators. Optional PHPStan and Mago integrations can help catch escaped mutants involving type violations, dead code, and unreachable paths. Installation options include PHAR, Phive, Composer, Git, and Homebrew. A browser playground supports trying PHP code and tests without installing the tools. Infection is free under the BSD-3-Clause license and requires PHP 8.3 or newer plus Xdebug, phpdbg, or pcov.
