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. -

Lura
Lura
An extendable, simple and stateless high-performance API Gateway framework designed for both cloud-native and on-prem setups. Consumers of REST API content (especially in microservices) often query backend services that weren’t coded for the UI implementation.

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. -

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. -

Apigene
Apigene MCP Gateway is the runtime layer that connects AI agents to APIs and MCP servers through the Model Context Protocol. It exposes agent tools, context, skills, and instructions as a single remote MCP endpoint that is fully managed and governed, making MCP native rather than experimental. Apigene provides the full agent foundation layer as one MCP Gateway, allowing agents to securely access APIs and MCP servers without custom glue code or framework-specific logic. Teams can build AI agents using chat, defining which APIs and MCP servers the agent can use, how it should reason, and how it should act without code. It supports intelligent tool selection, automatically matching the right API or MCP tool to each request, and multi-platform deployment across ChatGPT, Claude, Cursor, Gemini, VS Code, internal copilots, enterprise AI platforms, and custom apps.Starting Price: $200 per month -

Baidu AI Cloud API Gateway
Baidu AI Cloud
API Gateway provides comprehensive API management, including configuration, release, environmental management, privilege management, access control, on-line debugging, historical version management, document generation, and on-line sales. When using the API Gateway to manage APIs, the developer only needs to pay attention to the business logic of the API interface. Thus, it can achieve convenient, efficient, secure, and low-cost management services and provide data or capabilities to developers and partners. The backend can be configured with multiple addresses, and multiple backends can be polled according to the weight to improve the backend processing capacity; when any backend fails, the gateway can be recovered from any disaster according to a certain scheduling scheme. -

Inquir Compute
Inquir Compute
Inquir Compute is a cloud platform for deploying and running server-side code without managing servers, Kubernetes, CI/CD, or DevOps infrastructure. It lets developers create functions, APIs, webhooks, cron jobs, background tasks, and multi-step workflows directly from a browser-based editor or API. Users can write code in Node.js, Python, or Go, configure runtime settings such as memory, CPU, timeout, environment variables, and network access, then deploy and invoke it in isolated containers. Functions can be exposed through an API Gateway, triggered manually, scheduled, or combined into pipelines where one step passes data to another. The platform is designed for long-running workloads such as AI agents, scraping, document processing, data enrichment, integrations, and automation. It includes logs, traces, invocation history, error tracking, route management, API keys, tenant isolation, and observability tools. -

Apiary
Oracle
Write an API in 30 minutes. Share it with your teammates or customers. Let them use the API mock to take your API for a spin--without writing any code. Iterate, rinse & repeat. Coding can wait until you know what your developers really need. DNA for your API, powerful, open sourced and developer-friendly. The ease of Markdown combined with the power of automated mock servers, tests, validations, proxies, and code samples in your language bindings. It's often hard to see how an API will be used until you have the chance to code against it. What wireframes are for UI design, a server mock is for API design. A quick way to prototype an API - even before you start writing code. Two clicks will link Apiary to a repository of your choice. It’s up to you whether you make the API Blueprint private or public and let the community contribute. We update API docs every time you commit, and we push commits to the repo whenever you update your documentation at Apiary. It's a virtuous cycle.
