An Envoy-Powered, Kubernetes-Native API Gateway

About kgateway

Kgateway is:

• An ingress/edge router for Kubernetes: Powered by Envoy and programmed with the Gateway API, kgateway is a world-leading Cloud Native ingress.
• An advanced API gateway: Aggregate web APIs and apply key functions like authentication, authorization and rate limiting in one place
• A better waypoint proxy for ambient mesh: Use the same stack for east-west management as you do for north-south.
• An AI gateway for securing LLM usage: Protect applications, models, and data from inappropriate access or use, whether you're producing or consuming. Manage traffic to LLM providers, and enrich prompts at a system level.
• An LLM Gateway utilizing the Inference Extension project: Intelligently route to AI inference workloads and LLMs in your Kubernetes environment.
• A model context protocol (MCP) gateway: Federate MCP tool servers into a single, scalable and secure endpoint.
• A migration engine for hybrid apps: Route to backends implemented as microservices, serverless functions or legacy apps. This can help you gradually migrate from legacy code to microservices and serverless, add new functionalities using cloud-native technologies while maintaining a legacy codebase or allow different teams in an organization to choose different architectures.

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.

The project was previously known as Gloo, and has been production-ready since 2019. Please see the migration plan for more information and the current status of the change from Gloo to kgateway.
