What is Dropwizard?

Dropwizard is like a toolkit that gives you everything you need to build fast Java web applications without much hassle. Picture a Swiss Army knife; it seamlessly combines various tools into one easy-to-use format. Dropwizard wraps several well-known libraries:

• Jetty: For serving HTTP requests.
• Jersey: For RESTful web services.

• Hibernate Validator: For data validation.
• Metrics: For monitoring application performance in production.
