Kong - The Microservice API Gateway

•    Lua

---

Kong is a cloud-native, fast, scalable, and distributed Microservice Abstraction Layer (also known as an API Gateway, API Middleware or in some cases Service Mesh). Backed by the battle-tested NGINX with a focus on high performance, Kong was made available as an open-source platform in 2015. Under active development, Kong is used in production at thousands of organizations from startups, Global 5000 and Government organizations.

grpc-gateway - gRPC to JSON proxy generator following the gRPC HTTP spec

•    Go

---

grpc-gateway is a plugin of protoc. It reads gRPC service definition, and generates a reverse-proxy server which translates a RESTful JSON API into gRPC. This server is generated according to the google.api.http annotation in your gRPC service definition. It helps you to provide your APIs in both gRPC and RESTful style at the same time.

express-gateway - A microservices API Gateway built on top of ExpressJS

•    Javascript

---

Express Gateway is an API Gateway that sits at the heart of any microservices architecture, regardless of what language or platform you're using. Express Gateway secures your microservices and exposes them through APIs using Node.js, ExpressJS and Express middleware. Developing microservices, orchestrating and managing them now can be done insanely fast all on one seamless platform without having to introduce additional infrastructure. Express Gateway is commerically supported LunchBadger. For more information about support plans please contact info@express-gateway.io.

pushpin - Reverse proxy for realtime web services

•    C++

---

Pushpin is a reverse proxy server written in C++ that makes it easy to implement WebSocket, HTTP streaming, and HTTP long-polling services. The project is unique among realtime push solutions in that it is designed to address the needs of API creators. Pushpin is transparent to clients and integrates easily into an API stack. To assist with integration, there are libraries for many backend languages and frameworks. Pushpin has no libraries on the client side because it is transparent to clients.

Ocelot - .NET core API Gateway

•    CSharp

---

Ocelot is a .NET Api Gateway. This project is aimed at people using .NET running a micro services / service orientated architecture that need a unified point of entry into their system. However it will work with anything that speaks HTTP and run on any platform that asp.net core supports. In particular I want easy integration with IdentityServer reference and bearer tokens.

tyk - Tyk Open Source API Gateway written in Go

•    Go

---

Tyk is a lightweight, open source API Gateway and Management Platform enables you to control who accesses your API, when they access it and how they access it. Tyk will also record detailed analytics on how your users are interacting with your API and when things go wrong. Go version 1.8 or later is required to build master, the current development version. Tyk is officially supported on linux/amd64, linux/i386 and linux/arm64.

contour - Contour is a Kubernetes ingress controller for Lyft's Envoy proxy.

•    Go

---

Contour is an Ingress controller for Kubernetes that works by deploying the Envoy proxy as a reverse proxy and load balancer. Unlike other Ingress controllers, Contour supports dynamic configuration updates out of the box while maintaining a lightweight profile. Contour also introduces a new ingress API (IngressRoute) which is implemented via a Custom Resource Definition (CRD). Its goal is to expand upon the functionality of the Ingress API to allow for a richer user experience as well as solve shortcomings in the original design.

kuma - The Universal Service Mesh

•    Go

---

Kuma is a platform agnostic open-source control plane for Service Mesh and Microservices. It can run and be operated natively across both Kubernetes and VM environments, making it easy to adopt by every team in the organization. Bundling Envoy as a data-plane, Kuma can instrument any L4/L7 traffic to secure, observe, route and enhance connectivity between any service or database. It can be used natively in Kubernetes via CRDs or via a RESTful API across other environments like VMs and Bare Metal.
