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.

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 do you like best about the product?
1. The usage is relatively straight forward.
2. The UI feels modern and intuitive eversince their recent UI change.
3. Extremely performant!
4. I've never encountered any sort of down time.

What do you dislike about the product?
1. Integrating with some server platforms may not be as straight foward.
2. The public API could be simpler to use, with better documentation.

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
An overall good utility to setup feature flags in a new firm or project
What do you like best about the product?
ld-proxy that aggregates requests & caches flag values locally, saving tons of round trips and is very easy to setup, usage history, flexible values using json.
What do you dislike about the product?
Annoying to change flags across environments (we have quite a few of them), even in the new beta view. No ability to fall back to "code defaults", as I must always define _some_ default which is always taken instaed of what's defined in code.
What problems is the product solving and how is that benefiting you?
Mostly gradual rollout of features
I like the new UI which allowed me to control my flags values across all environements
What do you like best about the product?
I mostly like the "History" feature and the evaluations feature
What do you dislike about the product?
It's hard to change flag type, meaninig if in mistake I make an boolean flag instead of string I need to delete my flag and recreate it
What problems is the product solving and how is that benefiting you?
I am using LD mostly to create a feature flags.
Easy to use SDK to control feature flags
What do you like best about the product?
Easy to integrate SDK
Easy to use web UI
Easy to use web UI
What do you dislike about the product?
Hard to manage numerous flags across multiple environments without writing additional tools/scripts
What problems is the product solving and how is that benefiting you?
Incrementially launch new features
Good for what it does
What do you like best about the product?
Helps with feature flags and limits. Easy to use and haven't had any issues with it.
What do you dislike about the product?
It can get hard managing flags when there are too many variations
What problems is the product solving and how is that benefiting you?
We use Launchdarkly for feature management as well for quota management. Launchdarkly makes it quick and easy to make changes without having to redeploy new code.
