# Confidence Flag SDKs

> Integrate Confidence Flags into your apps with OpenFeature-compatible SDKs for Swift, Kotlin, JavaScript, React, Java, Go, Python, Rust, and Flutter.

Confidence Flags provides SDKs for multiple languages and platforms, with the goal of managing flag resolving in all of your systems.

Confidence Flag SDKs support the [OpenFeature](https://openfeature.dev) standard, a project
from [Cloud Native Computing Foundation](https://www.cncf.io/) (CNCF) that aims
to standardize feature flagging. When operating flags with OpenFeature, the Confidence Flags SDKs
only give the configuration needed for the OpenFeature SDKs to connect to Confidence Flags.

The high-level concepts and semantics are shared across the SDK portfolio,
but for more granular documentation of each single SDK you can find the source code and README
at the repositories linked below:
