Tomcat vs Undertow

Developers should learn and use Tomcat when building and deploying Java web applications, particularly those based on servlets and JSPs, as it offers a robust, standards-compliant environment with minimal overhead compared to full Java EE application servers 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.

Tomcat

Nice Pick

Developers should learn and use Tomcat when building and deploying Java web applications, particularly those based on servlets and JSPs, as it offers a robust, standards-compliant environment with minimal overhead compared to full Java EE application servers

Pros

• It is ideal for production environments requiring high performance, scalability, and ease of configuration, such as in microservices architectures or standalone web services
• Related to: java-servlets, java-server-pages

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. Tomcat is a platform while Undertow is a tool. We picked Tomcat based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Tomcat wins

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