We use LaunchDarkly to decouple Deployment and Release. We can focus on testing with the flag off initially - this should prove that the new code is not being called and existing functionality has not regressed. We can then be confident that master can be deployed to production at any time with the flag off without causing any problems. Once we have tested flag off we can focus on testing flag on to ensure the functionality is working. Once we are happy, we can then release the flag at whatever time suits the team and the business, and it is a non issue as there are no code deployments at release time.

Being able to easily target individual or groups of users for internal or external testing is very powerful. Being able to quickly change these targeting rules, and the new feature of change requests to allow your change to be reviewed before being applied is great from a process point of view. The insights graph is fantastic at showing the variants that users are receiving and allows you to identify when a flag is ready to be removed.

Some functionality like User Segments is very powerful but only available in the enterprise licence. The change request functionality is only optional at this time and cannot be enforced - ideally we would want changes to rules in production to only be allowed once they have been reviewed.

Feature flagging is such a game changer and LaunchDarkly make it so easy. The UI and logic is incredibly easy to navigate and follow. Giving us the ability to test in production is huge and made such a difference to our production development.

The API's are a little cumbersome to get our head around with the response properties not as clear as they could be. However once you have got your head around the terminology it is all good.

Solid tools. Allowed us to deploy more safely.

Flags were a valuable tool to safely deploy with many teams working on the same stack.

No real issues with the software. I view the product as mature.

Easy to use for developers and friendly, being used in backend front and mobile - SDK are nice to use

Flag depreciation could be much better if we had more details for the flags and calls. Also there could be a automation to help and encourage the FF depreciation

The most I like about the launch darkly is feature flag management. We can implement the launch darkly in our code when we are working on a agile methodology, it is easy to use the feature flags as it keeps track of your codebase with each and every feature development.

Nothing I dislike about launch darkly as such. But when we are using a feature flag during production code deployment. More security features would be helpful.
