Show HN: Twinrun – run old and new code on the same inputs, diff the outputs
说明与用途
Twinrun 允许在相同输入下同时运行旧代码和新代码，并对比输出，适用于回归测试和兼容性检查，尤其在原型或内部工作流程中非常有用。采用时需手动检查依赖、文档和近期活跃度，项目的生产就绪度为中等。确认无误后，可将其集成到 CI 流水线或测试套件中，实现可靠的输出对比。
实际用途
Show HN: Twinrun – run old and new code on the same inputs, diff the outputs may be useful when its README and activity match a concrete workflow.
限制与审查说明
Medium: useful for prototypes or internal workflows, with dependency and maintenance checks before production.
