What do you like best about the product?

What I value most about LaunchDarkly is how it provides a single, unified platform that makes our entire product lifecycle more efficient and data-driven. It’s an indispensable tool for every role I've held. For me, the ease of implementation is what makes all of this possible. Getting it set up was straightforward, and it immediately provided value by separating code deployment from feature release.

From a Product Manager's standpoint, the ease of use and the sheer number of features are huge wins. The user interface is so intuitive that anyone on the team can set up a feature flag, manage a rollout, or even run an A/B test without needing to be an engineer. This empowers me to move faster on product decisions and enables a true culture of experimentation.

As a Data Analyst, the ease of integration is key, as LaunchDarkly's data export capabilities allow me to stream real-time feature flag events directly into our data warehouse. This gives me a rich, contextual dataset to analyze feature performance and user behavior with incredible granularity. Ease of implementation to such flags/features to branch out and connect to platforms

And as a former Client Support professional, what stands out is the combination of ease of use and customer support. If a customer has a unique issue with a feature, I can use the same intuitive interface to turn that feature off for their account instantly. On the rare occasion we hit a technical roadblock, their documentation is comprehensive, and their support team is always responsive and helpful.

It's not a tool we use once a month; its sheer frequency of use makes it a daily part of our workflow, from development to deployment to analysis. LaunchDarkly has become the single source of truth for our feature releases, and that's a level of control and insight that's hard to imagine operating without.

What do you dislike about the product?

t's interesting to consider what might be a "dislike" about LaunchDarkly, though from my experience, it's less about disliking a feature and more about what the tool is—and isn't—built for. It's so good at what it does that any perceived "dislike" is really just a matter of perspective or a limitation of a specific use case, not a flaw in the product itself.

For instance, some teams might initially find the pricing model to be a dislike, but that's often a misunderstanding. The value you get from preventing outages, running successful experiments, and enabling a safer, faster release process far outweighs the cost. It's a strategic investment that pays for itself by reducing risk and accelerating innovation.

Others might say that managing a high number of feature flags can become complex, especially for large, fast-moving teams. But this isn't a flaw with LaunchDarkly; it's a symptom of a larger process problem. LaunchDarkly provides the tools to manage that complexity—like standardized naming conventions, tagging, and descriptions—which actually forces a team to be more disciplined and organized. The tool itself encourages better habits, which is a good thing in the long run.

Ultimately, my experience with LaunchDarkly is that it does exactly what it's supposed to do, and it does it exceptionally well. Any "dislike" is usually an opportunity to better understand the tool's capabilities or to improve our own internal processes.

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

"The primary problem LaunchDarkly solves is decoupling the release of code from the deployment of features. In our work with the Aetion Evidence Platform, this has provided a profound benefit, particularly given the rigorous, evidence-based nature of our product.

The core problem: Without LaunchDarkly, releasing a new feature or making a change means we have to go through a full code deployment. In a highly regulated space like real-world evidence (RWE) analytics, this process is complex, time-consuming, and high-risk. Every new build requires extensive validation and can't be done on a whim. This creates a bottleneck, slowing down our ability to innovate and respond to customer needs.

How LaunchDarkly solves it and benefits us:

Mitigating Risk in a Regulated Environment: The Aetion Evidence Platform is used to generate critical real-world evidence for life sciences and biopharma. Errors are not an option. LaunchDarkly allows us to wrap new functionality in a feature flag, deploy the code to our production environment, and keep it dormant. When we are ready, we can turn it on for a single client or a small cohort, get a full validation cycle on real data, and then roll it out progressively. This 'kill switch' capability is a massive safety net; if an issue arises, we can turn off a feature in seconds, without a new code rollback, minimizing any potential impact on our customers' critical analyses.

Accelerating Innovation with Controlled Experimentation: Our clients and partners in the life sciences industry are constantly looking for faster ways to answer complex questions about therapeutic value. LaunchDarkly enables us to safely test new analytical methods or user interface improvements directly in the Aetion Evidence Platform. We can create an experiment, expose a new visualization or workflow to a specific group of users, and measure its impact. This allows us to make data-driven decisions on what features to build and scale, ensuring we are delivering what our users truly need and that new features are valuable and validated.

Empowering Non-Technical Teams: The ability to manage a feature's lifecycle through a simple UI empowers our product and client support teams. They can grant a client early access to a new reporting tool, enable a pilot for a specific study, or troubleshoot an issue by toggling off a feature for a single user. This drastically reduces the dependency on engineering resources for routine tasks, freeing up our developers to focus on building new, impactful capabilities for the Aetion Evidence Platform.

What do you like best about the product?

I appreciate how LaunchDarkly's feature flags make it easy to manage feature releases. In cases where a solution needs modifications post-production, I can simply turn off the feature flag, apply changes in a lower environment, and redeploy without hassle. This ease of toggling features is a significant advantage.

What do you dislike about the product?

I find setting up LaunchDarkly initially challenging, especially when working on a back-end application using Node.js. There were environment-specific configuration issues, and there were no clear instructions on how to handle them. I had to rely on a colleague's configuration to resolve my issue. Additionally, the support provided wasn't very effective, as their suggested solutions didn't work. I also notice a lack of tutorials or videos that provide step-by-step instructions on how to use specific versions of the library, which would be beneficial for users like me.

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

LaunchDarkly's feature flags allow me to easily disable and modify features after production release, avoiding code reversion and easing deployments. It's beneficial for handling production changes smoothly.

LaunchDarkly minimizes incidents to nearly zero, decreases resolution time from hours to minutes, enables safe code deployment, and reduces fear of breakage with feature flags.

What do you like best about the product?

LaunchDarkly has made our release process so much smoother. Being able to roll out features gradually and turn them off instantly if something goes wrong has saved us a few headaches already. I like how easy it is to set up flags and target specific users or environments without extra deployment work. The dashboard is clear, the flags update instantly, and the SDKs fit nicely into our stack without a lot of fuss. It’s one of those tools you quickly get used to and then can’t imagine working without.

What do you dislike about the product?

The biggest drawback for me is the cost — it can add up pretty quickly if you have a lot of flags or multiple environments. Managing a large number of flags in the UI can also feel a bit clunky at times. I wish there were more bulk-edit options and a slightly more flexible permission system for larger teams.

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

Before LaunchDarkly, we had to coordinate deployments very tightly and roll back code changes manually if something went wrong — which often meant unnecessary risk. Now, we can decouple deployment from release, roll out features to a small percentage of users, and instantly toggle them off if needed. It’s also made it easier to experiment with features in production without impacting all users, which speeds up our feedback loop and reduces stress for both devs and product teams.

What do you like best about the product?

I appreciate LaunchDarkly's ease of use, especially the straightforward process for creating feature flags. It simplifies releasing new features and provides the ability to quickly disable them if issues arise. I find individual targeting and the UI very effective, with the targeting allowing for precise control over which users see specific features. Additionally, the ability to create allow and block lists is invaluable for ensuring specific user access. The rollout features and plan scheduling further streamline my workflow.

What do you dislike about the product?

I find the new user interface to be complex compared to the previous version. The old UI was simpler and easier to understand, making navigation and viewing variations straightforward. In the new UI, the main content area is smaller, with the left and right parts taking up a significant portion of the space, which makes it less intuitive to use initially.

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

I use LaunchDarkly for easy feature flag creation, managing feature releases, and individual targeting, which aids in controlled rollouts and minimizes risks by allowing quick disabling of faulty features.

What do you like best about the product?

Initially, we approached highlight because the current ecosystem lacks good logging tools, but we saw the potential to remove our error reporting tool and our frontend session tool. After using the logging tool, we did exactly that. Not only do we now have logging, error reporting, and sessions, but they have a consistent through-line - via traces - that ties them all together. The whole team, from app-support to developers are able to use LaunchDarkly easily; we now use it exclusively and all the time - for every bug or ticket we encounter. Integrating it into existing javascript code is as simple as adding a single sdk call and adding logs for it to consume; sessions are set up just as easily. The team at highlight/LaunchDarkly has worked with us from day one and answers all of our questions or requests quickly and efficiently. They take issues seriously and resolve them.

If you're not using this tool, you're missing out!

What do you dislike about the product?

I can confidently say that there is nothing more I could want!

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

We use most of the feature set of LaunchDarkly. It gives us full insight into the performance of our applications from simple "What happened in this case?" events to "How is the app performing as a whole". The team no longer has to take sessions and error reports and try to match the timing and environment. They're all connected in the tool. Session Replay in particular is offered by scant few in the industry and tying it to logs and bug reports is even better! The UI is clean and easy to navigate, unlike comparable tools which are filled with unnecessary tabs and options that clutter the screen.

What do you like best about the product?

Our team evaluated several APM products, but each time we found that they would require a significant investment of time and resources to learn, implement and maintain. That changed when we discovered LaunchDarkly’s APM product (formerly Highlight.io). From the start it felt like the right fit, covering the areas we needed visibility into without feeling overwhelming. The UI is intuitive and the metrics are straightforward and easy to follow.

The customer support has been excellent. The LaunchDarkly team has consistently been responsive to our questions, attentive during the sales process, and equally engaged after implementation.

Two features we turn to the most are: session tracking and session replay. Being able to view detailed session data alongside a visual playback of what the user experienced has been useful for troubleshooting. The ability to link session data directly to errors has been a significant improvement over our previous tools.

Another feature we’ve found useful is the Weekly Digest. It provides a high-level view of sessions, usage, and errors across multiple environments for the past week which is a great tool for managers and overseeing multiple applications and environments.

What do you dislike about the product?

We have not really had any issues. As an early customer of the APM product, there were some issues initially getting all the various .NET frameworks running, but their customer support team handled those quickly and got us up and running.

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

When applications experience performance issues, we use the suite of tools to quickly identify where to start and more efficiently diagnose root causes.
