Support for Amazon CloudWatch Evidently ending soon

After careful consideration, we have made the decision to discontinue CloudWatch Evidently, effective 10/17/2025. Active customers will be able to use the service as normal until 10/17/2025, when support for the service will end. During this period, we will continue to provide critical security patches, but will no longer support any limit increase requests. On 10/17/2025, the service will be discontinued and access to the service and any capabilities provided by this service will end. At this time, we recommend completing active feature launches and experimentation before 10/17/2025 to avoid impact.

As an alternative to CloudWatch Evidently, we recommend that all new feature flag-based launches transition to use AppConfig, a feature of AWS Systems Manager. If you have performed client-side evaluations using Evidently, you are already onboarded to AppConfig which supports current CloudWatch Evidently feature launch capabilities. Additionally, AppConfig’s Segments/Split feature will support experimentation when used in conjunction with your data warehouse/data lake. Please see blog post on how to start using feature flags in AWS AppConfig or the Getting Started page for a more in-depth introduction to AppConfig.

If you have additional questions, please contact us at AWS Support or via your Technical Account Management contact.
