APIs and microservices are the backbone of modern applications, enabling seamless communication between systems. With the rise of cloud computing, IoT, and AI, over 90% of developers now use APIs in their applications (Postman API Report, 2025).

To build scalable and efficient APIs, developers rely on powerful API gateways and microservices frameworks. This article explores four top frameworks that simplify API development and microservices architecture:

✔ Tyk – API Gateway & management tool
✔ KrakenD – High-performance API Gateway
✔ Moleculer – Microservices framework for Node.js
✔ Goa – API framework for Go

Let’s dive into these frameworks and discover how they can enhance API performance and scalability! 🚀

What Are API Gateways & Microservices Frameworks?

🔹 API Gateways act as a single entry point for API requests, handling authentication, rate limiting, and load balancing.
🔹 Microservices frameworks simplify the development of decentralized, scalable applications by breaking them into smaller, independent services.

✅ Why Use API Gateways & Microservices Frameworks?
✔ Improved security with authentication & rate limiting 🔐
✔ Faster performance with caching & load balancing ⚡
✔ Scalability for handling millions of API requests 🌍
✔ Easier maintenance with modular microservices 🛠️

Now, let’s explore the best API & microservices frameworks in 2025! 🚀
