We use the solution for risk-free releases, allowing us to control the blast radius when launching content to our customers. We also use it for targeted experiences, enabling us to reach specific customer segments with various features as they are rolled out. However, the company's main use case was extensive A/B testing to conduct experiments.

Must tool for any Software Engineer / Product manager
What do you like best about the product?
The intuitiveness of the features and the granularity of the level with which we can customize our feature flags
What do you dislike about the product?
Probably price. It's a bit costly but it is worth it definitely for safely launching new features
What problems is the product solving and how is that benefiting you?
LaunchDarkly helps me safely deploy and rollout my features across different environments and regions
Best product for A/B testing and feature flags
What do you like best about the product?
Setting up flags on different environments, Setting up variations, clear usage indicators.
What do you dislike about the product?
The difference between default value and off variation is a bit confusing at times.
What problems is the product solving and how is that benefiting you?
LD helps control a feature rollout and being able to rollback by just turning a switch. Combined with analytics, it helps with A/B test different variations of a flow.
Great features but can be tough to use
What do you like best about the product?
Easy to create new flags to maintain our services
What do you dislike about the product?
Search is really bad, and sometimes its confusing

Feature managemetn
Seemless experience with adding feature flags
What do you like best about the product?
- I love the fact that we can see the code references for each of the feature flags added which makes it easy to identify stale flags and remove
- Can create complex conditions on feature flags through segments/contexts
- Can create complex conditions on feature flags through segments/contexts
What do you dislike about the product?
I don't know if it's already supported but it would be great if we could get notifications of the stale flags/flags that do not have not been evaluated for more than a certain timeframe
What problems is the product solving and how is that benefiting you?
- Ability to easily add and control the release of a feature flag
Powerful Real Time Feature Flagging
What do you like best about the product?
The feature flagging system, particularly its ability to act as a kill switch, is incredibly useful. I also love the percentage rollout feature and the ability to add multiple variations within a single flag. Real-time flag updates that enable instantaneous UI changes are a standout feature.
What do you dislike about the product?
The new UI feels a bit confusing, probably because I got so accustomed to the previous version. Additionally, the updated UI could benefit from an onboarding guide or lessons to help users get up to speed quickly.
What problems is the product solving and how is that benefiting you?
LaunchDarkly helps us streamline feature management by allowing us to release new features behind flags, ensuring we can easily turn them off if needed. This flexibility reduces the risk of deploying untested or problematic features. Custom attributes enable us to target specific teams and users, providing more personalized feature rollouts. Segments are used to manage large groups of teams, making feature targeting more efficient. With LaunchDarkly’s APIs, we can update these segments in the background, adding backend automation to the process. Additionally, the group-by feature allows us to organize experiments by teams, improving our ability to track performance and gather insights.
Essential Tool
What do you like best about the product?
Documentation is great. UI is intuitive.
What do you dislike about the product?
UI is a bit dated. Getting started is a bit of a pain but once you build up momentum it's fine.
What problems is the product solving and how is that benefiting you?
Allowing us to effectively stage features at a low level.
Good Feature Flagging System
What do you like best about the product?
How easy the platform is to use, how easy it was to train the team + implement/integrate
What do you dislike about the product?
I'd prefer a more robust experimentation platform - LD's experiments are great but cannot do what a more full-featured tool can do.
What problems is the product solving and how is that benefiting you?
Able to roll out more targeted smaller releases to cohorts
Provides risk-free releases with control access and A/B testing
What is our primary use case?
What is most valuable?
The application is highly intuitive. The UI offers robust controls, allowing you to set rules, schedule releases, and establish dependencies. For instance, if a particular flag depends on other flags or features that need to be deployed first, you can also configure that. The application provides a deep level of configuration options.
What needs improvement?
When the system has an excessive number of feature flags, managing them can become cumbersome. It would be helpful to have UI elements that make this easier, such as tracking feature flag usage, the duration that feature flags have been open, and generating reports.
You need some experience to get used to it. There's a bit of a learning curve, but it is easier for people with a technical background,
For how long have I used the solution?
I have been using LaunchDarkly for one and a half years.
What do I think about the stability of the solution?
We experienced one brief outage with the system, which almost did not impact us. LaunchDarkly maintains a local copy of your rules, so our system usually functions. However, our ability to set up new feature flags was limited.
I rate the solution’s stability a nine out of ten.
What do I think about the scalability of the solution?
It's designed for scale. We didn't have a considerably large footprint, with most use cases involving single users at a time. They have a large user base of about a hundred million customers, but these customers typically visit once or twice. However, LaunchDarkly is used by companies with significantly larger footprints, proving it is designed for scale.
How are customer service and support?
Support was game-changing for the organization in terms of its ability to release things with a significant risk reduction. It has pretty comprehensive documentation.
How was the initial setup?
The initial setup is very easy.
What other advice do I have?
It allowed us to deploy faster. Despite having a rigorous code review process that slowed things down, once the code was reviewed, LaunchDarkly enabled safe deployments. If there was ever an issue, we could easily roll back a particular release by simply turning off the feature flag.
When configuring and setting this up, begin with feature sets that are relatively small in scope. This helps build the necessary skills to leverage the product effectively while maintaining control over the blast radius, thus reducing risk to your customers and application in case of misconfiguration. As you gain more experience with the solution, it's crucial to have a process to manage feature flag sprawl, as mentioned earlier. Implementing a life cycle management system for your feature flags is essential.
Overall, I rate the solution a nine out of ten because of its intuitiveness and ease of use.
Very robust for feature flag management and A/B testing

What problems is the product solving and how is that benefiting you?
Management of feature flags is a complicated task in a large organization, where partioning by regions and environments is crucial.
I've used inhouse systems before and LaunchDarkly seems to really productize the process of managing feature flags, making it fairly simple and performant to use even in a large organization.

Good product. Meets the requirements I need.
What do you like best about the product?
You can see the history of the flags and investigate in case of problems
What do you dislike about the product?
It is not possible to change simultaneously in several environments, but you have to change the value of a per-environment flag
What problems is the product solving and how is that benefiting you?
Gradually rollout of new features and changes
