They eliminate continuous integration bottlenecks by parallelizing workloads, isolating flaky assertions, and accelerating developer feedback loops. When choosing the right engine, prioritize native framework compatibility, concurrency limits, and how effectively the reporting tools surface root causes for failed builds.
