Introducing Network Traffic limits for all plans

Aug 1, 2023

We are introducing Network Traffic limits for all plans. The usage is based on the Network Traffic your applications are making to the ConfigCat CDN.

Why are we introducing these limits?

Our cloud provider charges us for the Network Traffic we use to serve your feature flags. By introducing these limits, we can cover these costs and continue providing the service. Instead of raising prices for all users in general, we decided to specifically reflect the network-related operation costs in our current pricing plans.

What are the limits?

20 GB / mo100 GB / mo1 TB / mo4 TB / mo

What to expect?

94% of our users will not be affected by these limits. If you are in the 6% that exceeds the limit, we will reach out to you directly to assist in the next 3 months in finding the best solution for your specific use case. Rest assured that even if you exceed the limit, your feature flags will continue to work seamlessly.

If you have any further questions or need assistance, please don't hesitate to reach out to us. We're here to help!
