Easy to hit the ground running feature flag and configuration SaaS tool
What do you like best about the product?
In both a personal and professional capacity LD has been easy to integrate with. Their SDKs are plug'n'play.
What do you dislike about the product?
Using launch darkly for configuration can be a bit tedious especially when dealing with JSON variations. Navigating around the JSON input does not feel natural, and the review box (diff tool) does not hightlight field changes very well, if at all.
What problems is the product solving and how is that benefiting you?
Feature flagging and configuration management. Config management means less engineer input into certain features when other stakeholders in the business can own the config.
Comprehensive solution for feature flag management
What do you like best about the product?
LaunchDarkly offers a complete full-featured platform for managing our feature flags. The interface is straightforward, the documentation is complete, and the customer success support has been very helpful. Most importantly we haven't encountered any operational issues in production related to our use of LaunchDarkly.
What do you dislike about the product?
The broad scope of LaunchDarkly functionality also means it can be difficult to be sure we are using it to its full potential.
What problems is the product solving and how is that benefiting you?
LaunchDarkly allows us to activate technical preview features for specific customers only, and also allows us to hide features deployed through continuous delivery so that we can reveal them as part of a coordinated marketing release.
Feature flags made easy
What do you like best about the product?
I think one of the biggest advantages of using LaunchDarkly is the easy integration of libraries with application code. Simply register the LaunchDarkly client when bootstrapping the application, and make it available. All engineering levels can start working with feature flags in no time. Another great feature is the ability to target specific users and control how a flag's value behaves, which is excellent for piloting new applications in production. Even though we didn't use several integrations, seeing so many ways to connect LaunchDarkly to other apps is awesome. For us, the Slack integration was more than enough. Newer apps with no built-in feature flags would default to LaunchDarkly, increasing the frequency of use in the organization.
As far as I'm aware, we never reached out to Customer Support, so I don't have any useful comments to provide on that topic.

What do you dislike about the product?
Probably the website at the begining, but never was a dealbreaker. It does what it needs to do and after sometime I kind of like it.
What problems is the product solving and how is that benefiting you?
Streamlining the process for launching new features into production, controlling when to turn them on and off, increases engineers' confidence when deploying without affecting the running systems.
LaunchDarkly was and actually is a big game changer in our company.
What do you like best about the product?
A lot of possibilities to manage your product. Now we are using it on a daily basis. It is really easy to use, and if you explore it more you will find more and more useful things. "Easy to learn, hard to master". It was really easy to implement it in our environment. Contact with support was always a pleasure (Aaron is the nicest person I ve ever met).
What do you dislike about the product?
Implementation process was a little tricky. Not from the technical side but organisational. We didn't know that we can create one project for all platforms etc.
What problems is the product solving and how is that benefiting you?
It allows us to proceed to CI/CD. Now every team can work on its part of the product. Timelines and limits of regular upgrades do not stop them, they can do it alone. Fuckups on the production can be "fixed" quickly by switching off the flag, then the team has more time to investigate and fix the problem with no time pressure.
Powerful feature flag tool that we rely on
What do you like best about the product?
Very configurable - for instance, you can target any flag by any of multiple facts you send to the LaunchDarkly tool, and can use custom names for the contexts you use (such as "User" or "Enterprise").
Great modern JS SDK means you can do all your feature flagging on the frontend if you want, allowing neat tricks like React updating in real time when you toggle a flag on.
Thoughtfully designed and well-documented API means you can also fetch flags completely manually on the backend and handle them yourself.
The API also allows you to do admin things such as creating flags and setting targeting. In our case we had a senior engineer make tooling and scripts to use their API to synchronize it with our old in-house feature flag system, allowing us to shift to using LD seamlessly with no manual labor or risk of outdated targeting.
Product feels very well designed and is reliable and performant.
We have never had even a hint of a reliability problem, as far as I know they have had zero downtime problems.
They have a lot of features, many we don't even use such as scheduling flags, approvals, and especially, A/B testing.

What do you dislike about the product?
They find ways to inconvenience you by withholding features on the non-enterprise plans. There are parts of the UI where they tease you such as the flag compare tool, where it will show you what flags don't match across environments, but you can't have it copy the settings if you aren't on Enterprise. Overall there are too many of these, but I admit that most of them aren't vital to my usage.
The (MAU-based) pricing can get expensive if you have a lot of users/entities that you are targeting separately. Likewise, the seat-based pricing can get expensive if you need a lot of licenses.
Overall it is expensive. If software is your core competency, your needs are actually very simple (meaning you don't use a lot of their many advanced features and tools), and your usage level is high enough to hurt, you may be better off considering either a much simpler tool, or something simple that you support in-house.

What problems is the product solving and how is that benefiting you?
We use LaunchDarkly to allow us to protect all the code we push until it's passed QA and we're ready to launch a feature. We also use it to hold back a feature sometimes for a customer who isn't ready to migrate.
Successfully controlled multiple FFs in my app
What do you like best about the product?
easy to use - just create FF and swith targeting + possibility to use precise targeting with rules usage.
What do you dislike about the product?
Stale flag state after 90 days not always enough to rollout the feature.
What problems is the product solving and how is that benefiting you?
I can easily rollout new features without any fear of failure as I can killswitch any feature with just one button
Easy feature controls
What do you like best about the product?
Easy to control our feature list and extrapolate when someone is able to see a feature.
Easy to roll a feature back if a major issue appears and we're able to quickly implement new feature flags.
We integrated the library without issue.
Customer service was quick to respond on the rare occasion that we needed to reach out to them.

What do you dislike about the product?
N/A, we have had no issues with using LaunchDarkly.
What problems is the product solving and how is that benefiting you?
We're able to enable non-developers to take control of features for customers. Other services include targeted user testing, rollback of features and stagger releases if required.
Feature Packed and Easy to Use
What do you like best about the product?
LaunchDarkly has always been easy to integrate into our code and comes with powerful features that makes it effortless for us to roll out new features. Their SDKs make implimentation a breeze and their customer support is always helfpul whenever we have an issue.
What do you dislike about the product?
As the product grows, the admin interface gets a bit more complex. LaunchDarkly has a lot fo features so the adnim interface needs a lot of options.
What problems is the product solving and how is that benefiting you?
We replaced Google Optimize with LaunchDarkly for AB testing and it's been smooth. We also hide new features behind feature flags until they're ready to go live. This allow our code to be in production, even when it's incomplete. Once the feature is completed, we enable the feature flag and everything is live.
