You choose from three contract options for feature flag management. The Free option sets fixed caps: 10 feature flags, 2 environments, 5 million config downloads, and 20 GB network traffic per month. Both Enterprise options remove those caps, giving unlimited seats, users, and reads, plus 4TB traffic and 1 billion config downloads monthly. The two Enterprise options match on capacity. The difference is the second one adds software escrow, which stores your source code with a third party for release under set conditions. Config JSON downloads count each time your app fetches its configuration file.
Top-of-mind questions for buyers
What counts as one config JSON download for billing purposes?
A config JSON download is counted each time your app fetches its configuration file from the CDN. Reading flag values from the local cache does not count. One download can serve many flag evaluations. Frequency depends on your SDK polling interval, which defaults to 60 seconds.
What happens if I exceed the config download or network traffic limits on the Free option?
Your application keeps running if you reach a limit. The team will contact you to discuss meeting your needs. You can also lower usage by increasing polling intervals, using webhooks, or routing traffic through a self-hosted proxy that caches config downloads within your own infrastructure.
What does the software escrow add to the second Enterprise option?
Software escrow stores the product's source code with a neutral third party. That party releases the code to you only under agreed conditions, such as the vendor ceasing operations. The two Enterprise options carry identical capacity limits; escrow is the only difference between them.

A simple product to solve a critical need
Reviewed on 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
Reviewed on Feb 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
Reviewed on Feb 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
Reviewed on Feb 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.
