Lura

Lura provides a stateless, high‑performance API gateway framework that can be self‑hosted and used without subscription fees. It sits between clients and backend services, aggregating multiple sources into single endpoints and allowing responses to be grouped, wrapped, transformed, and reduced to the fields required by the UI. The framework supports HTTP(S) and, through its generic libraries, can be extended to other protocols such as RPC.

The project is delivered as a Go library, enabling developers to embed the gateway logic directly into their own applications or to build custom proxies from source. A rich ecosystem of middlewares and plugins lets users add functionality like OAuth authorization, security layers, or other processing steps while keeping the core lightweight and extensible.

Lura is open source under the Apache‑2.0 license, marked as stable, and is intended for both cloud‑native and on‑premise deployments. It is the underlying engine of the KrakenD API Gateway and can be reused in other projects that need a performant, configurable proxy layer.
