ConfigCat Feature Flags

What do you like best about the product?

Moving from hard-coded feature flags to a dynamic solution has been a significant improvement for our company. ConfigCat makes feature flags simple to set up and allows us to easily target specific groups and functionality. We’ve found value in ConfigCat across multiple teams and use cases.

What do you dislike about the product?

Our biggest challenge with ConfigCat is that the plan limits have not scaled well with our usage. We’ve reached the limits for both feature flags and network traffic, and upgrading represents a significant increase in cost. The feature flag limit is particularly restrictive because developers sometimes have to remove existing flags before they can add new ones, which creates unnecessary overhead and can slow down development.

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

ConfigCat allows us to manage feature releases dynamically without requiring code changes or deployments. We can gradually roll out functionality, target specific customers or groups, test new features safely, and quickly disable functionality if issues arise.

What do you like best about the product?

Easy to use, and flexible targeting rules

What do you dislike about the product?

Sometimes changes do not take effect immediately

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

Hide incomplete feature from users, targeting specific user group, change configuration dynamically, release management

What do you like best about the product?

The simplicity and the price. Setup is straightforward across our front end, backend and mobile apps, and targeting rules let us release features to specific customers or run controlled tests in production when something can't be fully validated in lower environments. It really helped us decouple deployments from feature releases, and the development team genuinely likes the developer experience the tool brings to our process.

What do you dislike about the product?

Nothing significant after two years in production.

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

Decoupling feature releases from code deployments. Flags used to live in config files, so every customer-specific release required a deploy, which stopped scaling as we shipped more features. Now engineering owns the flags and works closely with product to decide what ships and who joins each beta, without waiting for a deployment.

What do you like best about the product?

Previous Response: Great service and value, fair plans, does what we need, keeps getting better, no AI/LLM. Incredible customer service, very responsive to feedback.

What do you dislike about the product?

I honestly can't think of anything I dislike.

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

Feature flags are a critical capability to developing and release features to our apps and services. ConfigCat does that extremely well. The web UI works great and keeps getting better. The Slack integration helps the team stay up to date with flag changes.

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

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.

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.

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.

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.

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.
