Melody API Gateway

• Build Requirements: Golang 1.11+
• Melody Version: 1.0.8

Introduction

Melody is a high-performance open source API gateway to help you to sort out your complex api.

If you are building for the web, mobile, or IoT (Internet of Things) you will likely end up needing common functionality to run your actual software. Melody can help by acting as a gateway for microservices requests while providing load balancing, logging, authentication, rate-limiting, transformations, and more through middlewares.
