Introducing sensitive text comparators
Focusing on frontend applications, we introduced sensitive text comparators to make sure sensitive info (like email address, username) is kept hidden in targeting rules.

The main idea about our pricing is that our prices are fixed, deterministic and there are no hidden fees. Also we offer a forever free plan without requiring any commitment or credit card information. All features are available in all plans - even the free - helping the evaluation process of our customers.

There is a way to stream feature flag and configuration changes to the clients right when they happen. In some cases ConfigCat's pull based architecture does not completely satisfies the requirements when microservices need the latest values instantly, or mobile apps where polling sometimes is a battery consuming anti-pattern.

Students should have access to the highest-quality education available. So we partnered with @GitHubEducation and joined the GitHub Student Developer Pack.

As feature flags are getting popular, an ever-growing number of developers are facing the challenges associated with them.
No matter if you implement your own feature flag library, or choose a hosted feature flag service like ConfigCat, chances are high you want to use your feature flags in your frontend and in your backend services as well.
If your feature flags can be toggled on a central feature flag dashboard, such as
We love to get emails like the one above. And sometimes we do. 😃 Actually, more often than I've ever dared to imagine.
Part of the reason our users love us (well, when they do) are those million little tweaks we do to our feature flag service on a daily basis.
Normally we don't share those little tweaks and updates
