Flexible Advanced Targeting for Reaching Specific Segments

  • May 06, 2026
  • Review provided by G2

What do you like best about the product?
I like the flexibility it offers when you’re aiming for a specific segment, especially with its advanced user targeting options.
What do you dislike about the product?
When having multiple feature flags, sometimes it's hard to locate a specific one as the list is overloaded with info and it's hard to locate the desired one
What problems is the product solving and how is that benefiting you?
We are using configcat mostly for new releases. Also we use them for A/B tests

A simple product to solve a critical need

  • May 01, 2026
  • Review provided by G2

What do you like best about the product?
How quick and easy it was to set up. The design was very intuitive and we were able to get it integrated in our system in a matter of weeks.
What do you dislike about the product?
ConfigCat doesn't have as granular of permissions as I would like. Ideally I block some buttons from some people in the system. I'd also like the ability to see timestamps in my local timezone.
What problems is the product solving and how is that benefiting you?
We are able to add feature flags across our system and deploy safely. We've been able to increase our deployment speed since we're sure that we can flip feature flags off if need be.

ConfigCat Makes Gradual Feature Rollouts to Beta Testers Easy

  • February 26, 2026
  • Review provided by G2

What do you like best about the product?
We use it to deploy our features to production, visible only to internal users or a select number of beta testers. Then we can move more users into the new feature as we feel confident about the set up.
ConfigCat provides lots of options in terms of limiting the audience in different ways.
What do you dislike about the product?
I dont know actually. It works quite well.
What problems is the product solving and how is that benefiting you?
Deploying features to production environment more safely by being able to test them with limited impact. This benefits us in the way that there is less risk during the actual deploy so we can spend less time checking things.

ConfigCat Is Essential to Our Development Workflow and Product Launch Strategy

  • February 26, 2026
  • Review provided by G2

What do you like best about the product?
ConfigCat has become an essential part of our development workflow and our product launch strategy.
What do you dislike about the product?
The built-in analytics for flag evaluations are limited. It’s not easy to see how many users were exposed to a given flag or to track the impact of a rollout over time.
What problems is the product solving and how is that benefiting you?
ConfigCat has given us a lot of flexibility in how we roll out features to our user base. Its segmentation and targeting capabilities let us meet the needs of specific customer subsets without affecting the broader audience, and vice versa.

Straightforward Feature Flags That Deliver Real Value

  • February 17, 2026
  • Review provided by G2

What do you like best about the product?
What we like best about ConfigCat is how easy it is to use relative to the value it provides. Our teams were able to adopt it quickly, it handles our primary rollout and feature management scenarios well, and the pricing is very reasonable for the capability it delivers. It strikes a good balance between simplicity and effectiveness.
What do you dislike about the product?
As our usage has grown, managing flags across multiple products has become more complex than we’d like. Separating flags by configuration works well, but maintaining a common set of flags across products requires extra effort. Enhancements in cross-configuration organization or shared flag capabilities would be valuable as we continue to scale.
What problems is the product solving and how is that benefiting you?
ConfigCat solves the risk and coordination challenges that come with releasing new functionality. By allowing us to control feature rollout independently of deployment, we can test in production safely, target specific rollout scenarios, and mitigate impact if something doesn’t behave as expected. This has improved our release confidence and operational flexibility.

Reliable, Always Available, and Packed with Sophisticated Features

  • January 30, 2026
  • Review provided by G2

What do you like best about the product?
Reliable, Available, and has sophisticated features, which cover our configuration needs.
What do you dislike about the product?
The logical language for flag enabling can be abused by users, by crafting unnecessarily complex queries.
What problems is the product solving and how is that benefiting you?
Thanks to ConfigCat, we can deploy software updates without fear. If something goes wrong during deployment, with the usage of ConfigCat, alongside our convention to use it for hiding new features, we can quickly turn off newly deployed, wrongfully implemented software modifications.

ConfigCat helps us isolate features in a multi-team continuous delivery setup

  • July 09, 2025
  • Review provided by G2

What do you like best about the product?
For real continuous delivery, the development of features needs to be isolated, so that the code is ready to go to production at any time. ConfigCat does that for us flawlessly without any integration issues. Its usage has been self-explanatory and without further need of documentation or customer support. The overview of feature toggles across all environments is very helpful to see the general status of development in a project.
What do you dislike about the product?
The only thing that is not really easy to do with the way we use ConfigCat is the isolation of features that span multiple teams and/or services. We would need to define an overarching product for that.
What problems is the product solving and how is that benefiting you?
For real continuous delivery, the development of features needs to be isolated, so that the code is ready to go to production at any time. This means different services in a microservices environment can be released to production multiple times a day without needing to worry about unfinished code or unforeseen interaction of features.

Excellent Feature Flag system

  • July 06, 2025
  • Review provided by G2

What do you like best about the product?
- very easy and straightforward to implement with the many options they provide with their different SDKs for different languages.
- very responsive support
- extensive options to implement more advanced feature flags and rollout strategies
- Very competitive pricing in comparison to some of their competitors
What do you dislike about the product?
Their Dashboard sometimes has a little confusing UI, which could use some improvements.
What problems is the product solving and how is that benefiting you?
Previously, we used a mix of different homegrown feature flag solutions, which made it very difficult in our growing organisation to have a single approach to feature flag management.
This impacted our engineering team as we scaled up, not having a single solution made it harder to onboard new engineers.
With Configcat, we consolidate all our services to leverage it, and we have a single feature flag solution that includes a range of additional features, such as audit logging, stale feature flag tracking, and caching.
This enabled us to speed up development and roll out new features more quickly and safely, as we can use feature flags to roll out features more gradually in a controlled fashion. This improvement enhanced our reliability and customer satisfaction, as we catch bugs faster and only impact beta customers before rolling out to a broader audience.

What do you like best about the product?
Is so easy for new users start to create and integrate in our application
What do you dislike about the product?
there is nothing that i can mentionate, because we use it and we are loving it.
What problems is the product solving and how is that benefiting you?
Now we can rollout and control each feature we delivery, and now we can toggle a feature too when we have any problem.

Love the flexibility from the support team

  • May 30, 2025
  • Review provided by G2

What do you like best about the product?
The tool is great for the price to add to your platform out-of-the-box features for features progressive and segmented activation, pretty useful for running betas, a/b tests, etc.

Their support team is also great, highlighting where we are over the quota for instance and being flexible in us fixing certain things before asking to move to the next plan.
What do you dislike about the product?
Nothing that I'm aware of. Maybe the tool is not as sophisticated as others to support experimentation E2E.
What problems is the product solving and how is that benefiting you?
Easily target different users and customer segments with new features.
