## About

Unleash is an enterprise-grade feature management and feature flag platform designed to decouple feature releases from code deployments. It provides developer SDKs across numerous languages and frameworks, enabling progressive rollouts, A/B testing, instant rollbacks, and runtime kill switches. The platform can be self-hosted on internal infrastructure or deployed via managed cloud options, ensuring complete control over application behavior and compliance with enterprise security requirements.
