“It’s really easy to scale with Semaphore compared to Jenkins, where a lot of maintenance and overhead is required. When we need more concurrency we just upgrade. Semaphore just works for us.”

“Without parallel tests, our test suite would now run well past the hour mark from start to finish. The ability to split the test suite up across 12 or more jobs in Semaphore and have the test suite run in under 7 minutes is so important for us and it saves us a lot of development time.”

94% of our customers rated Semaphore support as great last month
