What do you like best about the product?

We have been using Launchdarkly feature flags for about 3 years now. We have been using them to run experiments, or as kill switches for various features. I would say, that they are straightforward to use. One thing that I like is how LaunchDarkly creates an event stream with the user's browser, and the value of the feature flag gets updated on all the clients as soon as you update the value of the feature flag.

We use it for almost every new feature that we build in the product, and we have easily integrated it with our MobX Library that is used for global state management, and it makes the integration even more simpler for the developers.

What do you dislike about the product?

The new UI that LaunchDarkly recently launched for feature flagging is not something that I like, I had built muscle memory for using the tool hence it has become a little tough for me to use it.

What problems is the product solving and how is that benefiting you?

- We use it to experiment with a new feature, and get analytics out of it before launching it for the entire user base.
- We are able to partially launch a feature to a subset of users, as we can very easily target to subset of users on the Product very easily using LaunchDarkly.
- Since LD uses an event stream, which modifies the value of the flag in the product as soon as it is updated from the LD Dashboard (without the need to refresh the page). We use use LD as a kill switch for features in which we not very confident about the implementation. With LD we are easily able to kill the code if anything goes south in real-time.
