Do you need an open-source API management solution for your business? A successful microservices architecture can be greatly improved by choosing the right API gateway. API-first businesses depend on a wide range of services to create APIs and provide value to their clients. Various technologies may be used to develop APIs. By using procedures and tools (internal or external), you want your APIs to be consistent with your users. Business API endpoints can be managed, authenticated, and used easier with open-source API gateways. These gateways don't care about your architecture, data type, or other API choices.

There could be different API types in a developed API program, for instance. Gateways can also manage microservices, mobile backends, partnerships, and even external services. Because of this significant presence, everyone is looking for the greatest API development guides and utilizing the insights to deliver an ultra-advanced and smooth experience to their target audience. If you thought building an API was challenging, try managing one.  

What exactly is an API Gateway?

Open-source API serves as a gateway for external customers. It is a component that serves as the application's entrance point. In other terms, an API gateway is an API administration server that has endpoint information. It can also do authentication, rate limiting, load balancing, and other functions. To obtain a better image of an API gateway, we must first understand why it is necessary to have one.

Why are API integration platforms used?  

There are many different types of applications that use APIs, both large and small. Whether you're creating a new API marketplace or launching a public API, APIs are changing how businesses are done. In the same way that HTTP servers serve websites in production, API gateways serve APIs in production. APIs can be delivered to clients and partners through API gateways. The proxy server sits in front of your API and handles functions such as authentication, rate limiting, redirecting endpoints to the appropriate microservices, and load balancing. Use an API management gateway to:

  • Create APIs by combining microservices.
  • Secure Microservices both internally and externally.
  • Provide modern APIs for legacy services.
  • Obtain business insights through Microservices and APIs.

 Top 10 Open source API gateways

1. Kong Gateway

Kong is one of the top priority open-source API gateways which is built on NGINX. Kong is committed to supporting a microservice API design at scale and provides a robust set of plugins to that end. It's designed to be modular and adaptable, so you just install the services that your team needs. Kong's Plugin Development Kit (PDK) also enables you to create plugins that extend Kong's functionality by utilizing Go or Lua (a C-based scripting language). As a result, Kong, its partners, and its big community has created a great number of plugins. If the core Kong API gateway does not already fulfill all of your organization's needs, you can use the existing plugin library or create a whole new plugin expressly for your use case. Kong may be the appropriate solution for you if you're seeking a community-driven, open-source API gateway.

2. Tyk

The MPL, under which Tyk is licensed, is not as liberal as Kong's Apache 2.0 license. The same gateway is used by Tyk's enterprise and community users simultaneously. There are no additional charges for certain enterprise features. Instead of requiring additional plugins and Lua scripts, Tyk is a plug-and-play API Gateway. There are no plugins required for OIDC, OAuth2, Bearer Token, Basic Auth, Mutual TLS, and HMAC authentication methods. Additionally, it supports XML to JSON, JSON to JSON, and JSON Schema validation. GoLang, a fast throughput and parallelism-optimized system language, is used to implement Tyk.

In addition to offering a cloud-hosted version, Tyk.io also offers professional assistance licenses. NGINX's GoLang may be more current and easier to program than Kong/Lua. Tyk offers interpreters for running plugins in other languages besides Golang, such as Javascript and Lua. The cloud version will require direct internet access, unlike the on-premises version, which will run within the same VNET as your internal services. Tyk includes features like Key Management, Quotas, Rate Limit, API version, and access control, but no integrated invoicing. 

3. KrakenD

Kraken is the most effective open-source API management platform. All of the API management solutions and tools mentioned above are open-source and ready to be a valuable addition to the tech stack. 

4. Gravitee.io

It allows for cluster deployment and dynamic service registration, as well as backend load balancing, API health checks, API detach and reconnect capability, and hot updates (continuously updates configurations without restart nodes).

6. WSO2 API Manager

WSO2 API Microgateway is mostly written in Java and streamlines the process of developing, implementing, and securing APIs in distributed microservice architectures. It enables the conversion of legacy API formats (both requests and answers) to current ones, allowing them to be exposed to modern consumer apps. Because WSO2 API Microgateway employs OpenAPI Specification (OAS), developers can collaborate to create APIs and then independently test them. Furthermore, it is very scalable because it may function in isolation with no reliance on other components.

7. Fusion
