CircleCI + LaunchDarkly

How CircleCI transformed their own continuous delivery using LaunchDarkly
I really like LaunchDarkly, and I’m glad we’re using it. I believe that feature flags are a critical piece of modern development, and LaunchDarkly brings this part of continuous delivery to the masses.

CircleCI Before LaunchDarkly
While CircleCI had engineers on staff who were savvy in feature flagging systems, they didn’t want the stress of building or maintaining something more sophisticated. Despite the perceived value of such a system, they didn’t want to take focus off of their core business.
Why They Chose LaunchDarkly
When they heard that buying a feature flagging system was an option, they jumped right in with a trial. Shortly after, they had implemented LaunchDarkly across the entire engineering and product teams and immediately started to see the results.
Being able to put control over who sees a feature in the hands of the product team makes a lot of sense. That's where LaunchDarkly enables something that should have always just been the case.
