  • “It’s outdated, it’s been there for too long, and it’s lagging behind. But people still keep using it and stumbling on the same mistakes and problems and resource consumption.”

  • “It was a heavy lift to figure out the logistics around their request."

  • “We use CircleCI to test all of the touchpoints between our platform and Drupal, for example, and create scripts that fire up the tests automatically.”

  • “We have to install OS-dependent libraries depending on the programming language used for a build, which requires getting root privileges for the CI tool used. It’s not a good idea to give engineers the root privileges for security reasons, so we needed to ask the CI tool administrators to install those libraries.”

  • "The UI is very easy to understand, it’s easy to get new engineers up and running, and CircleCI ensures everything works.”

  • “CircleCI has helped us automate lots of tasks, so developers only have to worry about building the product. That gives them the necessary focus to build faster and better.”

  • "CircleCI helped us improve build system simplicity and stability, which reduced the support requests from our teams by 90%.”

  • "The overall stability of CircleCI is remarkable in comparison to previously used CI providers and other cloud-based development tools.”

  • “CircleCI is the backbone of our software development lifecycle, since it allows us to push software faster, test things faster, and keep iterating.”

  • “When I give demos of Poplog and people ask, ‘How would you put that into the CI pipeline?’ I just say, ‘CircleCI.’ It’s that straightforward.”

  • “If your test suite takes an hour your minimum incident resolution time can’t be faster than an hour."

  • “With the process changes and automation improvements that CircleCI helped us introduce, we’ve gone from just one deployment every two weeks to eight deployments every day – a 64X improvement.”

  • “The biggest change for me was that a lot of things we used to have to do manually are now automated. We can fix things faster, and investigate faster.”

  • “Having flaky tests can be a major pain. Now we have data that we can quickly drill into.”

  • "Since we implemented Docker layer caching, we’ve saved about 2,000 hours of developer time in the last six months.”
