Netty vs Undertow

Developers should learn Netty when building high-performance network applications that require low latency and high throughput, such as chat servers, game servers, or microservices communication layers meets developers should use undertow when building high-throughput, low-latency web applications in java, especially for microservices or embedded scenarios where minimal resource usage is critical. Here's our take.

Netty

Nice Pick

Developers should learn Netty when building high-performance network applications that require low latency and high throughput, such as chat servers, game servers, or microservices communication layers

Pros

• It is essential for Java developers working on distributed systems, IoT platforms, or any scenario where efficient handling of thousands of concurrent connections is critical, as it outperforms traditional blocking I/O approaches
• Related to: java, nio

Cons

• Specific tradeoffs depend on your use case

Undertow

Developers should use Undertow when building high-throughput, low-latency web applications in Java, especially for microservices or embedded scenarios where minimal resource usage is critical

Pros

• It is ideal for real-time applications using WebSockets or for serving static content quickly, as its event-driven model outperforms traditional blocking servers like Tomcat in concurrent request handling
• Related to: java, wildfly

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Netty is a framework while Undertow is a tool. We picked Netty based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Netty wins

Based on overall popularity. Netty is more widely used, but Undertow excels in its own space.
