Open source feature flagging and experimentation platform for stress free deployments, measured impact, and smarter decisions.

GrowthBook Users

We didn't want to require that GrowthBook be in the critical rendering path

so the SDKs do the feature evaluation locally, which means the features and rules can be cached

you can do the evaluation on the API side if you like

you can even mix and match - our variation assignments will be the same with any of our SDKs

Okay cool :) thanks! I wondered if it might somehow mess up the stats/reporting, but it sounds like as long as we track at the time we check the flag status, that's the main thing
