Raj Kansagra - PeerSpot reviewer

Feature flags have transformed our deployments and empower fast, low-risk experimentation
There is definitely a learning curve for new team members when it comes to organizing and cleaning up flags in LaunchDarkly. Once a project scales, managing multiple flags can become cluttered, and performance could degrade if you do not stay on top of deprecating and maintaining the old flags. Having an easier way to do that would be pretty useful.In a microservices world, managing flag state changes and propagation across complex or heavily distributed backend architectures can introduce latency or consistency challenges. While the UI is clean and pretty intuitive, tracking conditional flag modifications across large engineering teams requires more robust historical audit logging.

It consolidates all logs into one place and provides required features and functionalities
Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to do RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"What stands out to me about LaunchDarkly is that it's super easy to use."
"I appreciate that we can release any feature in production and maintain control over it."
"The setup is easy."
"I like that it offers the ability to control the flags."
"LaunchDarkly has positively impacted my organization as the value we deliver to customers is much faster, and we saved a lot by using this feature instead of implementing it ourselves."
"LaunchDarkly is working great, and I would encourage them to continue their excellent performance."
"These features in my current project have helped my team because they allow us to specifically target users to start turning on functionality, we can monitor the behavior and make sure that it's behaving as expected when the feature toggle is turned on, and then we can increase the usage."
"LaunchDarkly has positively impacted our organization by transforming how we deploy software and manage risk."
"LogDNA consolidates all logs into one place, which is super valuable."
"With LogDNA, which brings all the logs together in an interleaved stream, it allows us to take a transaction and relate it to other contextual events making the gathering of evidence for auditors and our internal RCA much more productive."
"The solution aggregates all event streams, so that if there are any issues, it's all in the same interface."
"We haven't had anything yet that we couldn't do through LogDNA."
 

Cons

"I have used LaunchDarkly for around two and a half years and I haven't faced any issues with it."
"I think LaunchDarkly's customer support can be improved as it is not responsive."
"There is definitely a learning curve for new team members when it comes to organizing and cleaning up flags in LaunchDarkly."
"We need experience to use it, and the initial setup can be difficult. Also, sometimes it has breakdowns."
"LaunchDarkly can be improved by managing old flags. We have an issue with old flags; it became very messy very fast and we need to be very disciplined about managing these flags."
"When the system has an excessive number of feature flags, managing them can become cumbersome."
"If LaunchDarkly goes down and you don't have it set up right, it could be a problem for you."
"I believe LaunchDarkly is working very well, but making it easier to integrate with code bases or providing an AI component that assists customers by understanding their code bases and supplying easy-to-integrate code snippets would be very helpful."
"No ability to encapsulate a query or a filter, and communicate or share that among the team."
"Scalability could be improved; we are using it through the IBM cloud deployment and on some of the data centers that are very heavily used, there is a significant lag in the event stream, sometimes 10, 15 minutes behind, which makes the RCA impossible."
"Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem.
