# Feature Store CaraML Feature Store are built upon another open source project [Feast](https://feast.dev/). From CaraML Maintainer's perspective, we have customized Feast to be more suitable for our use case, and lean more towards a production ready system. Work is in progress to provide documentations for CaraML's take of Feast and how it integrates with other CaraML components, stay tuned! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
