Ultra performant API Gateway with middlewares. A project hosted at The Linux Foundation.

An open framework to assemble ultra performance API Gateways with middlewares; formerly known as KrakenD framework, and core service of the KrakenD API Gateway. An extendable, simple and stateless high-performance API Gateway framework designed for both cloud-native and on-prem setups.

Lura is an API Gateway builder and proxy generator that sits between the client and all the source servers, adding a new layer that removes all the complexity to the clients, providing them only the information that the UI needs. Lura acts as an aggregator of many sources into single endpoints and allows you to group, wrap, transform and shrink responses. Additionally it supports a myriad of middlewares and plugins that allow you to extend the functionality, such as adding Oauth authorization or security layers.
