| Purpose | ArcMutate extends PiTest to find bugs missed by tests through mutation testing for Java, Kotlin, and Android software. | Stryker performs mutation testing by inserting changes into code and running unit tests against the changed code to assess test effectiveness. |
| 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. | Stryker says it mutates only source code to avoid false positives. |
| Support | The homepage lists community support with Base and priority support with Pro. | The documentation directs users to Slack for help and bug discussions, with bug reporting guidance also available. |

In their own words
Stryker Mutator
Stryker Mutator is mutation-testing software for JavaScript, TypeScript, C#, and Scala. It changes source code in more than 30 defined ways, then runs unit tests against those variants to show how effectively the tests detect faults. The project supports incremental analysis, parallel execution, surviving-mutant reports, and mutation quality gates. It is test-runner agnostic, with listed integrations including Cucumber, Jasmine, Jest, Karma, Mocha, Tap, Vitest, and a command runner. Code analysis and parallel test-runner processes are used to speed runs, although the FAQ notes that mutation jobs can be slow and recommends improving unit-test performance or limiting files. Stryker is free, released under Apache 2.0, and available through API or self-hosted use. Its cloud dashboard stores reports and mutation-score badges, free for open source, with GitHub account setup and github.com as the supported Git provider. Reports can be sent directly or by HTTP PUT with an API key.
