The most widely deployed gateway in Kubernetes for microservices
## About kgateway
Kgateway is the most mature and widely deployed gateway in the market today. Built on open source and open standards, **kgateway is a resilient and performance-oriented control plane that implements the [Kubernetes Gateway API](https://gateway-api.sigs.k8s.io/) for [Envoy](https://github.com/envoyproxy/envoy)**.
With a control plane that scales from lightweight microgateway deployments between services to massively parallel centralized gateways handling billions of API calls, kgateway brings omni-directional API connectivity to any cloud and any environment.
### Use Cases
Kgateway is designed for:
* **Next-Gen API Gateway**: Expose APIs and apply policies like authentication, authorization and rate limiting in one place. Powered by [Envoy](https://www.envoyproxy.io) and programmed with the [Gateway API](https://gateway-api.sigs.k8s.io/), kgateway is a world-leading Cloud Native API Gateway.
* **Hybrid Application Migration**: Route to backends implemented as microservices, serverless functions or legacy apps. Gradually migrate from legacy code while maintaining existing systems.
* **Complex Tenancy Environments**: Multiple personas and teams can work with kgateway to express their APIs, with concepts like route delegation and composable policies.
Kgateway is feature-rich, fast, and flexible. It excels in function-level routing, supports legacy apps, microservices and serverless, offers robust discovery capabilities, integrates seamlessly with open-source projects, and is designed to support hybrid applications with various technologies, architectures, protocols, and clouds.
> [!IMPORTANT]
> Kgateway previously acted as a control plane for the agentgateway dataplane to enable several AI and agentic features.
> Starting with version 2.3.0, the control plane for agentgateway has been migrated to the [agentgateway](https://github.com/agentgateway/agentgateway) repo, enabling a singular focus for kgateway to be a stable, robust, and battle-tested API Gateway powered by Envoy.
### History
The project was launched in 2018 as **Gloo** by Solo.io and has been [production-ready since 2019](https://www.solo.io/blog/announcing-gloo-1-0-a-production-ready-envoy-based-api-gateway). Since then, it has steadily evolved to become the most trusted and feature-rich API gateway for Kubernetes, processing billions of API requests for many of the world's biggest companies. Please see [the migration plan](https://github.com/kgateway-dev/kgateway/issues/10363) for more information about the transition from Gloo to kgateway.

## Thanks
Kgateway would not be possible without the valuable open source work of projects in the community. We would like to extend a special thank-you to [Envoy](https://www.envoyproxy.io) and [agentgateway](https://github.com/agentgateway/agentgateway), the two data planes upon which we build our dual control plane architecture.
