Feature flags have enabled cautious rollouts and have supported fast, coordinated launches
Reviewed on Oct 16, 2026
Review provided by PeerSpot
What is our primary use case?
Regarding my use cases, I am cautious about breaking customers in production, so I generally put LaunchDarkly flags on pretty much any feature that is going to be rolled out to production to slowly roll things out and ensure nothing is broken. Additionally, it is valuable for developing a new feature and then launching it all at once when it is ready to go, so I do both of those.
I am not using LaunchDarkly to manage any AI in production, as other teams may be doing that. At the moment, my use of AI is limited to coding assistance, while other teams are integrating AI into the product.
What is most valuable?
What I appreciate most about LaunchDarkly is that it is very easy to use. I estimate I have around 30 flags, though I have not counted them recently. Finding the flags is straightforward; I search for the flag I need and then proceed with the setup for whatever I need to do. One useful aspect for my workflow is that whenever I set a flag or change something, I ask my coding LLM to confirm that everything is working as it should, whether it is to catch a typo or ensure I did not add the wrong merchant ID.
What needs improvement?
What I dislike about LaunchDarkly is the inability to quickly find all the flags I have currently running and their statuses. I want to know if they are rolled out partially, but I have to check externally by asking my coding agent about all my LaunchDarkly flags and their statuses. Recently, I forgot about a flag I rolled out to a couple of merchants, and I noticed I was not alone; several people had flags running for months with only one or two merchants enabled. A feature to alert me if a flag is underutilized or needs attention after a week of being rolled out would be beneficial.
For how long have I used the solution?
Overall, I have been working with LaunchDarkly for a couple of years, having used it at Instacart and currently at Thanks, but it was not utilized at Thomson Reuters. I have a couple of years of experience with it.
What do I think about the scalability of the solution?
I have not encountered any scalability issues with LaunchDarkly. I work for a mid-sized company with hundreds or thousands of users, and I have not run into scalability issues here. While my experience at Instacart might have been different, I was not using it as in-depth as I do now. I currently use LaunchDarkly on a daily basis.
What other advice do I have?
I have not integrated any other tools with LaunchDarkly; it stands by itself in my usage.
Other than the server that checks the status whenever I request it, which saves me from going directly to LaunchDarkly, I do not have additional tools integrated.
I would give LaunchDarkly a rating of nine out of ten because I never give out tens, as that implies no room for improvement, and everybody can improve. Overall, LaunchDarkly is good; it is easy to use, and I can see what is happening relatively quickly.

Vega Unreliable: Slow Trace Loading, Missing Data, and Hard-to-Find Sessions
Reviewed on Oct 16, 2026
Review provided by G2
What do you like best about the product?
In some cases, I’m able to view logged API responses. Searching for sessions is also pretty straightforward, especially if you already know the time and the user you’re trying to find.
What do you dislike about the product?
Vega hasn’t been working for me at all. If you don’t know exactly who you’re looking for and when, sessions are very hard to find. LaunchDarkly flags can also be difficult to track down, including the rules and where they’re being served from. Often I can find a session, but then there’s no information in the trace data, so it’s practically useless. On top of that, loading traces is very slow and hit-or-miss.
What problems is the product solving and how is that benefiting you?
I usually review session replays to see what the API calls contain and check whether anything looks off.

Reviewed on Oct 15, 2026
Review provided by G2
What do you like best about the product?
The best thing that Launch Darkly lets us do is implement client specific requests and hide it behind a flag for other clients effortlessly.
What do you dislike about the product?
The manual part of setting flags by logging in the website.
What problems is the product solving and how is that benefiting you?
Gating client specific features from other users, it is helping in shipping code faster!

Flexible Feature Flags and A/B Testing with Plenty of Options
Reviewed on Oct 15, 2026
Review provided by G2
What do you like best about the product?
The amount of options and flexibility when setting up flags and AB tests
What do you dislike about the product?
The UI is sometimes hard to navigate, some options sometimes are hard to find or are named similarly but serve different purposes
What problems is the product solving and how is that benefiting you?
Feature flags and AB tests, launch darkly allows me to manage the percentage of users that get some features easily. Also it allows us to do trunk based development by hiding WIP features

Super Simple UI/UX and Effortless MCP Integration
Reviewed on Oct 14, 2026
Review provided by G2
What do you like best about the product?
Super simple UI/UX. Easy to integrate: I just have my AI agent call the MCP and manage our flags for me.
What do you dislike about the product?
Nothing so far. We've integrated it across 2 programming languages without any issues.
What problems is the product solving and how is that benefiting you?
Scaling up agentic development: feature flags allow us to go fast while still having guardrails in place. An agent can't do anything that we can't turn off with a toggle.

Useful Audit Trail and Reliable Performance
Reviewed on Oct 11, 2026
Review provided by G2
What do you like best about the product?
The audit trail is really useful whenever someone asks why a feature was enabled or when a change went live. Instead of piecing together the full timeline from scattered messages, I can quickly see what happened and when. I also appreciate that it gives me the breathing room to spot unexpected changes before they reach everyone, while still providing complete support and consistent performance.
What do you dislike about the product?
Sometimes I need more context about a flag’s business purpose. The technical names alone don’t tell me which financial reports or downstream metrics could be affected, and the UI could do a better job of surfacing that information so it’s easier to find when I need it.
What problems is the product solving and how is that benefiting you?
During month-end analysis, I struggled to tell whether a discrepancy was coming from the data itself or from a newly introduced change. Reviewing flag configurations alongside our data integrations helped narrow down the root cause, and the AI-assisted analysis let us investigate much faster without wasting hours digging through unrelated reports.

Instant Feature Toggles, Blazing Performance, and Clear Change Reviews
Reviewed on Oct 11, 2026
Review provided by G2
What do you like best about the product?
Having the ability to enable feature toggles on the fly, instantly, is amazing. The performance is through the roof.
The UI/UX is very easy to understand, and I like that you can clearly review exactly what we’re changing with every request—what goes out and what comes in, whether we’re renaming something, and so on.

What do you dislike about the product?
I couldn’t find an option to apply a change across multiple environments in a single request. It seems I have to create separate requests for each environment, and also handle each flag separately.
What problems is the product solving and how is that benefiting you?
It’s great not having to wait for a pipeline to finish, and I also don’t have to worry about accidentally “breaking” a YAML/JSON file.

Feature Flags That Make Releases Safer, Faster, and More Controlled
Reviewed on Oct 09, 2026
Review provided by G2
What do you like best about the product?
I like being able to release code and switch features on separately, because it gives us more control over when changes actually reach users. For example, we can decide whether a specific user or organisation should receive a different value.
Gradual rollouts also help us introduce features to a small group first, gather feedback, and build confidence before moving to a wider release.
Being able to switch a feature off quickly is particularly useful if something goes wrong, since it reduces the pressure to rush out another deployment just to undo a change.
Finally, having feature flags in one place makes it easier to see what’s enabled and to manage changes consistently across environments.

What do you dislike about the product?
I’d like to be able to create rule templates. For example, if I create a handful of flags to gate new features, I want to set up one reusable rule that enables them for my test user/shard/whatever, and then apply that same rule to all of those flags at the same time.
What problems is the product solving and how is that benefiting you?
Being able to move very fast in an AI driven environment and still safely gate changes and test/iterate without affecting end users.

Turn features on and off in seconds, with no redeploy
Reviewed on Oct 09, 2026
Review provided by G2
What do you like best about the product?
LaunchDarkly gives our team the confidence to release often while keeping production stable. Staggered rollouts managed by LD flags help us control and mitigate any unwanted production downtimes. Simple to use and easy to navigate UI makes it easy to adapt. LaunchDarkly MCP and Slack automations is also an added advantage.
What do you dislike about the product?
There is Targeting rules can be confusing when many services share a flag. It’s hard to see why a flag gave a certain value. Old flags pile up - there should be feature to automate archival flags when not in use. The price can go up quickly as the team and usage grow.
What problems is the product solving and how is that benefiting you?
We release more often and with more confidence. Fewer customers are affected when something goes wrong. Incidents are fixed faster because turning a flag off is quick and safe. Product and support teams can control feature access without asking engineers for a new release.
