After you ship your feature, you’re probably wondering… Is it working? Are people using it? Rather than trying to track down data in other tools that don’t have your feature flag’s context, you can now do it all in one place. Turn your feature on, see its impact on our new Feature Flag Monitoring view. To start, we’ll show errors and web vitals (LCP, CLS, and INP) on a system-wide level with flag change annotations overlaid to see correlation. Coming very soon, this will get leveled up significantly to scope the metric data just to the users evaluating your flag. We’ll also be adding session replays for your flag, user counts per variation, additional metrics, and much more!

To activate Feature Flag Monitoring, just initialize our client-side observability plugin to get started.
