What are API Gateways in the USA?
API gateways act as centralized entry points that manage, secure, and route requests between clients and backend services in an application or microservices architecture. They handle essential functions such as authentication, rate limiting, load balancing, caching, and request transformation to optimize performance and security. By consolidating these controls, API gateways simplify communication, reduce latency, and ensure consistent governance across multiple APIs. They also provide analytics and monitoring to help developers track usage and detect issues in real time. Ultimately, API gateways improve scalability, reliability, and security for modern, distributed applications. Compare and read user reviews of the best API Gateways in the USA currently available using the table below. This list is updated regularly.

Apache Knox
Apache Software Foundation
The Knox API Gateway is designed as a reverse proxy with consideration for pluggability in the areas of policy enforcement, through providers and the backend services for which it proxies requests. Policy enforcement ranges from authentication/federation, authorization, audit, dispatch, hostmapping and content rewrite rules. Policy is enforced through a chain of providers that are defined within the topology deployment descriptor for each Apache Hadoop cluster gated by Knox. The cluster definition is also defined within the topology deployment descriptor and provides the Knox Gateway with the layout of the cluster for purposes of routing and translation between user facing URLs and cluster internals. Each Apache Hadoop cluster that is protected by Knox has its set of REST APIs represented by a single cluster specific application context path. This allows the Knox Gateway to both protect multiple clusters and present the REST API consumer with a single endpoint. -

Express Gateway
Express Gateway
Developing monolithic applications doesn’t work. Monolithic applications are being broken down into microservices. These microservices expose the application as set of APIs that can be consumed by anyone. Microservices and APIs is an architectural style that’s grabbing a lot of attention due an emphasis on sustainable development. If you’ve used Node.js, you’ve almost certainly come across Express.js. Express.js (Express) remains one of the largest, most widely adopted, open source projects in the world. Simplicity means that, as a minimalist, general purpose, framework that is familiar to every Node developer out there you can get started rapidly and continue that velocity throughout the API Development Lifecycle. We believe that an Express based API Gateway will be a powerful enabler for developers to sustainably build better, faster and more scalable applications. -

SmartBip
RetAPPs
SmartBip is the name of our platform: it works as a Middleware / API Gateway between the internal systems of the retailer and the App and Web frontends, providing services that optimize and secure dialogue between the parties. RetAPPs was founded in 2012 by Alessandro Tiretta, who still today provides the company with his expertise in the retail industry. He saw that traditional brick-and-mortar retailers could benefit from innovative tools as they tried to compete with online boutiques, both in terms of customer engagement and loyalty, and in order to respond to the new needs of manufacturers. And indeed, today the data confirm just that. RetAPPs is the ideal partner for traditional retailers because it’s a fully-digital solution provider, able to support retailers throughout the entire digitisation process, resulting in their success: to do so, we came up with SmartBip, proprietary technology that turns any point of sale into a multi-channel e-commerce platform.
